Introduction
The Bird fiber distributed antenna system (Fiber‐DAS) was developed from the start with fiber‐optic cable as the
distribution medium. This allows for excellent radio performance and best in class system noise figure of less than
3 dB, from the remote unit antenna port to the base station interface port.
The Bird Fiber‐DAS system is a flexible and scalable solution, meaning the system can be tailored for almost any
requirement. This flexibility provides the user the ability to adjust many of the systems parameters to fit their
specific needs.
This manual contains design, installation, and commissioning guidelines, as well as system maintenance practices. It
also contains information regarding general practices within in the industry as well.
Fiber-DAS calculator — In addition to this manual, the Fiber‐DAS calculator is an indispensable tool, this Excel
spreadsheet includes the following features, providing insight to how well the system will perform:
System Noise Figure calculator
Intermodulation performance calculator
Uplink / Downlink Balance
Dynamic headroom
RF on fiber
A fiber distributed antenna system (Fiber‐DAS) is an efficient method of transmitting radio signals over large
distances. Our Fiber‐DAS can provide as much as 30 km of fiber between the head‐end and the remote unit,
providing that the radio access technology used in the Radio Access Network (RAN) does not suffer timing issues and
that the fiber loss is within the specification.
The Fiber‐DAS uses an infra‐red light source, modulated with the combined radio signals that need to be
propagated. The fiber channel system is ultra wide‐band, ranging from 88 MHz up to 2600 MHz, thus covering most
types of radio communication systems including as FM broadcast, VHF communication radios, LTE, TETRA, GSM,
CDMA, WCDMA and many other radio access technologies.
Most land mobile radio and cellular systems use Frequency Division Duplex (FDD) which means:


Two separate fibers, one for the uplink (signals from the terminal towards the base station) and one for the
downlink (signals from the radio base station towards the terminal)
Or a single fiber and the signals must be multiplexed using different wavelengths.
Bird’s Fiber‐DAS uses wave‐length division multiplexing (WDM) as the standard configuration featuring the
following:.
Single mode fiber
Angled connectors
Up to 15 dB optical loss
Note: Separate UL/DL fibers can be used if it is necessary or desired.
The dynamic of the fiber is good enough to tolerate multi‐carrier, multi‐band and multi‐operator solutions, but they
share the available dynamics and if there is a large number of carriers the fiber attenuation needs to be considered.
Because the modulation is analog the system requires the fibers to be of single mode type. All connectors used in
Bird’s Fiber‐DAS equipment are SC‐APC type with a 7° angle. It is important that all connectors (i.e. patches)
between the Master Unit (MU) and the Remote Units (RU) be angled, otherwise reflections could result causing
problems with the quality of the signals through the system.

System Description
The Fiber‐DAS system typically consists of three main segments:
Gateway — The Gateway acts as a firewall ensuring internal traffic on the system remains internal and at the same
time allowing a web interface for monitoring and supervision. The gateway also handles SNMP traps.
Headend — The Headend serves as the interface with the operator’s base station, housing the units required to
transmit and receive communications between the operator’s base station and the remote units of the Fiber‐DAS
system.
Remote Units — the remote units are located near the distributed antennas and house the equipment necessary
to transmit and receive communications between the antenna and the headend.

Gateways
The gateways offered include the Central Gateway (CGW), Base Station Gateway (BGW) and Remote Gateway
(RGW).
For remote supervision of a Fiber‐DAS a gateway (RGW or BGW) is installed. BGWs and RGWs are typically located
with the headend equipment, the RGW is a smaller compact embedded solution while the BGW is a full featured
Linux server that can be set up in many different ways.
CGWs are used for monitoring multiple Fiber‐DAS systems, communicating with the BGWs and RGWs.
Central Gateway (CGW)
The CGW is used to provide a single remote access point and to compile alarms from multiple BGW/RGW networks.
The unit is a self‐powered Linux based server.
Base Station Gateway (BGW)
The BGW assigns IP addresses to all the modules in the Fiber‐DAS system, including the Headend and Remote Units
as well as their components.
The BGW is a self‐powered Linux based server.
Features of the BGW:
Web interface configuration
Automatic detection of modules
Automatic detection of Remote Units
Capable of handling large systems
Functions for statistics
Fiber Distributed Antenna System (Fiber DAS)
Northbound communication to CGW
Includes firewall to protect local net
Portal to your Master Unit
User‐provided certificate based security via HTTPS
Figure 2
Base Station Gateway
The BGW has two Ethernet ports ‐ INT and EXT.


The INT port is connected to the internal network in the headend’s Master Unit to provide the local
network for all the modules and the Remote Units. It also provides, via the built‐in switch in the Master
Unit, a way of locally configuring the network. It provides the web interface for all the settings of the
system as well as many other functions.
The EXT port is a “northbound” Ethernet port that allows the BGW to connect to the Internet, or a WAN/
MAN type of larger network. This means that the system can be monitored and managed remotely.
The BGW is the unit responsible for alarm handling and remote forward of alarms either by SMTP mail forwarding or
by SNMP traps. A MIB file for your SNMP system is available from Bird upon request as well as documentation
regarding SNMP.
If the BGW is replaced the Remote Units may not show up immediately. This is due to the lease time on the address
they have. Eventually they will request a new address and when this is done they will show up.
The BGW can also launch VPN tunnels to a remote supervision center, the CGW. The CGW makes it possible to
manage multiple systems from a single location.The CGW can handle a large number of such tunnels, providing a
central point for supervising all the installations and collecting alarms and statistics from all the systems as well as
centralized alarm management. The BGW can support a second VPN tunnel to the Bird management center
providing supervision and management assistance, if needed.

System Description
Remote Gateway (RGW)
The RGW is a small unit similar to the BGW but intended for small systems where there are only a few remotes or
where there is no headend. The RGW has a form factor that allows it to be mounted inside a repeater casing.
The RGW can be used to run up to 4 Remote Units from a single Repeater on a single Fiber. The RGW has the
capability to connect northbound to a CGW, just like the BGW, and it can also forward alarms through a VPN tunnel
to a CGW.
The memory capacity and features are reduced compared to the BGW but for a small system with a single fiber this
is an option.
In remote locations without Ethernet, the RGW can be equipped with a modem to allow remote access to the
system. Typically a 3G modem is used allowing a VPN tunnel from the RGW to a CGW, enabling supervision,
monitoring and control of the system.
Headend
The headend consists of a 19‐inch rack with modules that are selected depending on the system design. Generally all
headend Units contain:



Network switch ‐ connects communication paths between the modules
Interconnect Unit (ICU) ‐ RF splitter/combiner (rack‐mount unit or module in the MFU)
Master Frame Unit (MFU), may contain some or all of the following:
Power supply
Base Station Interface Unit (BIU)
Fiber‐Optic Interface card (FOI)

A DHCP server built into the RGW and BGW will assign IP addresses to all the headend subunits in the rack and the
Remote Units when they are connected to the system. The configuration is automatic and creates a protected sub‐
net for the system.
DCS - Network Switch
The network switch is an AC powered, 24‐port switch with Spanning Tree Protocol (STP). The network switch
provides an Ethernet link between the MFU and the BGW. Each card slot in the MFU has a dedicated Ethernet port,
each port is connected to the network switch and the network switch is connected to the BGW.
A DC powered option is also available.
Actual network switch may be

Fiber Distributed Antenna System (Fiber DAS)
Master Frame Unit (MFU)
The Master Frame Unit (MFU) houses the Power Supplies, Base Station Interface Units (BIU), Interconnection Units
(ICU), and Fiber‐Optic Interface (FOI) cards. Figure 3 shows an MFU equipped with 3 BIUs, 6 FOIs and one Power
Supply.
Figure 3
Master Frame Unit
Functional description
One MFU supports several modules, or combination of module types. The modules can be placed anywhere in the
frame. There are 16 single slot card positions in each MFU, however module widths vary (see each module’s
specifications) so the number of module that will fit in an MFU depends on the module type. One MFU can house up
to 4 power supplies, 8 ICUs, 8 wide BIUs, 16 slim BIUs, 16 FOIs, or combination of modules. See Table 2 .
Each MFU requires at least one power supply, although the power supply does not need to be housed within the
MFU. Quite often a system has more than one power supply and they are usually placed together in one MFU for
easy access. Each MFU has two power input connectors, one primary and one redundant. A redundant power supply
connected to an MFU ensures continued operation if one of the power supplies should fail.
The MFU contains two ventilation fans circulating ambient air through the units housed in the frame. These are high
quality fans with a high mean time between failure (MTBF).
Each Module in the MFU are assigned an IP addresses via DHCP leases, modules inherit the MAC address from the
backplane, this ensures that a new module inserted in the rack receives the same IP address as the one it is
replacing, without the need of manual configuration.

Base Station Interface Unit (BIU)
The Base Station Interface Unit (BIU) is the interface between the operator’s base station and the Fiber‐DAS system.
The primary purpose of the BIU is to adjust uplink and downlink signal levels.The BIU is powered from the MFU
backplane and communicates via Ethernet with the BGW.

The BIU has uplink and downlink RF connectors on the front panel and is available in two variants, one containing
duplex filters or one with separate uplink/downlink paths, depending on the needs for the connection to the base
station. In most cases the duplexed version with a combined DL/UL ports is used.
In addition to duplexing options, there is a single slot and a dual version of the BIU:


The DBI3xx (wide version) includes an external alarm connector (DB9) and requires two MFU slots.
The DBI3xxC (compact version) does not have an external alarm connector (DB9) , and uses only one MFU
slot.

Functional description
The BIU has four SMA ports (female type) to connect the RBS/BTS.


Duplexed versions have combined DL/UL connectors used to connect to the RBS, and there are UL test (TP)
connectors that can be used to monitor the signal out from the BIU.
Non‐duplexed (simplex) versions have the test connectors replaced by UL connectors and the normally
combined UL/DL connectors are replaced by DL only connectors.
Fiber Distributed Antenna System (Fiber DAS)
The BIU has four QMA ports (female type) that are normally used to connect it to an ICU.


There are two uplink (input) ports and two downlink (output, TX) ports.
These are two separate paths, the isolation between DL 1 and DL 2 ports and the isolation between the UL
1 and UL 2 ports is > 50 dB.
There are two separate RF paths in the BIU. The BIU is configured for the specific frequency band it will serve. The
two paths in the BIU cannot have different frequencies; a GSM 900 BIU will have two GSM 900 paths and cannot be
combined with an 1800 path. Separate frequencies require the use of an additional BIU.
RF patch cables are used to patch the DL and UL paths (QMA) to the ICU.
The DBI 3xx (dual slot) BIU has an alarm output port (DB9 female connector) on the BIU which can be used to
connect external alarms.

The BIU is technology neutral and the downlink path contains settable attenuators that can be used to adjust the
signal strength to proper levels before feeding them into the ICU. In the uplink there is an amplifier followed by a
settable attenuator used to adjust the signal and the noise level into the base station uplink.
CAUTION
Overdriving the RF source input into the BIU will cause permanent equipment failure and
will void the warranty. The installer must ensure that input levels are not exceeded.
Plan for maximum power out of the RF source and attenuate accordingly with external
attenuators if needed.
All RF connections are made on the front of the BIU. The maximum recommended input power to the BIU is 30 dBm.
A high power alarm is activated at > 30 dBm and a low power alarm at < 10 dBm input power.
Input power above the recommended level can cause permanent unit failure. For high power base stations, an
attenuator should be used to ensure that the input power to the BIU can never exceed specifications.
There is a 0 dBm input version of the BIU available on request.

System Description
The schematic in Figure 6 shows one of the channels in the BIU. The signal detector for the downlink level alarms is

BIU Indicator Operation
There are two LEDs located on the BIU front panel. One is the power LED (green), the other is the alarm LED (red).
Both LEDs indicate a number of states by different flashing sequences, see Table 7 .
In an error state the web interface should be used to check the actual condition of the BIU but the LEDs can give a
quick indication on the state of the unit. The LEDs are also useful for locating the physical unit if several BIUs are
installed in the same rack.

Interconnect units (ICU) are used to couple signals between the BIUs and the FOIs.
The functional purpose of the ICU is:


Downlink ‐ Split the signal from the BIU and route the balanced signals (minus insertion loss) to the FOIs.
Uplink ‐ Combine the signals from the FOIs and route the sum of the signals (minus insertion loss) to the
BIU.
The RF ports on the ICU are QMA.

The FOI converts the RF signals in the downlink to fiber‐optical laser output that is transmitted on the fiber to the
remote unit. It also receives the laser light transmitted by the Remote Unit and converts it back to RF signals that are
then routed to the ICU and/or BIU.

WARNING
Avoid looking into connected fibers and receptacles.
The laser used in this system is a Class 3b laser that produces invisible infra‐red coherent light. Not safe to view
with optical instruments. Always put the protection caps on unused fibers and receptacles.
This interface is designed to work with SC‐APC connectors (8° angled physical connector) and single mode fibers
only. All connectors between the master unit and the remote unit must be APC, otherwise problems with reflections
will arise, which could cause severe problems in the system.
The Ethernet communication between the Headend and the Remote Units takes place on two sub‐carriers in the FOI
where the Ethernet signals are superimposed on the RF signals.
As shown in Table 10 , Bird offers two styles of FOI cards. The "DOI300 Series FOI" on page 16 and the "DOI401Series FOI"

DOI300 Series FOI
The DOI300 series supports a single fiber optic link. The fiber‐optic interface can either be a WDM (DOI302) which is
most commonly used or an optional duplex feed with separate UL and DL fibers (DOI301). Bird also offers a WDM
option (DOI380x). The WDM utilizes the duplex feed style card but the wavelength for the downlink are defined by
the "x" in the DOI380x part number. Note that the Remote Unit will need to be ordered with the correct WDM
uplink wavelength. Refer to the chart for the WDM wavelengths offered.
DOI300 Series Serving Multiple Remotes
The DOI300 Series FOI can serve up to 4 Remote Units on a single fiber run when using an optical splitter in the first
Remote Unit. When utilizing the DOI302 WDM module each Remote Unit in the series must have different optical
wavelengths in the uplink path to avoid interference.
When utilizing optical splitters, the optical loss of the splitter must be accounted for in the optical link budget. The
DOI300 series FOI has a maximum link budget of 15 dBo.
shows the allowed FOI to FOR/Remote configurations. Bird offers various splitter options for the FOR/
Remote to help account for optical losses. The standard optical splitter will have balanced outputs for each path.

Functional description
The FOI has a nominal gain of 35 dB and the laser transmitter should see a maximum composite input power of
0 dBm. This means that for 0 dB attenuation in the downlink a maximum input of ‐35 dBm composite power is
recommended (when attenuators are set to 0 dBm). If the downlink attenuator is set to a higher value the maximum
recommended input is adjusted accordingly.
The output power of the laser is calibrated to 3000 ÂľW. This can be used to check the loss over fiber in the remote
because the remote reports the received optical levels. The loss may be different in the uplink compared to the
downlink because of different wavelengths on the laser.
The FOI contains several adjustable attenuators which are used to compensate for loss before the FOI (e.g. in the
ICU) and for loss on the fiber in the uplink. There are two sets of RF ports on the FOI that can be used to connect
signals from two different strips in the rack‐mount ICU, or two different MFU ICUs.
is a block diagram showing the downlink path in the FOI and how the test port is connected. There are two
attenuators that can be set in the downlink path. This allows for balancing the input signals from two different signal
sources so that they can share the dynamics of the laser properly.

The RF drive levels are measured and accessible in the web interface.
TP DL is a test point measurement port for the downlink path. The RF level at TP DL will be the same as the input to
the DL ports minus the GUI attenuator settings.
TP DL = “DL IN 1" minus “Att. 1 Downlink 1" minus “Att. 2 Downlink 1".
TP DL = “DL IN 2" minus “Att. 1 Downlink 2" minus “Att. 2 Downlink 2".
Example: Input into DL is ‐25dBm with the GUI setting for “Att. 1 Downlink 1" of 10 and a GUI setting for “Att 2
Downlink 1" of 0. The test point measurement will be: ‐25dB (input) minus 10dB (attenuator #1) minus 0dB

The DOI401 four port FOI is very similar to DOI302 expect that it has four WDM optical ports instead of one. This
allows the user to install dedicated fibers to each Remote Unit without having to balance optical splitter link budgets
for each remote in a group. The balanced splitter loss is accounted for in the 7 dBo link budget of the DOI401. Unlike

PSU
DC Power Supply
AC Power Supply
Functional description
The AC power supply can handle up to 16 cards or one chassis full of cards. The DC power supply is capable of
handling 11 cards or one full chassis that includes the DC power supply.
All connectors are on the front side of the power supply. Figure 18 shows the PSU equipped with European power
inlet.
The PSU outputs are two 10‐pin Molex connectors, these are connected to the chassis to supply power. One
connector should always be connected to the chassis holding the PSU (for driving the fans).
One chassis can hold up to 4 power supplies. Two PSU’s may be connected to a chassis to provide redundancy.

Remote Unit (RU)
Remote units are available in a wide range of frequencies, gain and output power to cater to support a variety of
requirements. Remote units are also capable of supporting more than one frequency band in a single unit.
Chassis types
Remote units (RUs) are available in two chassis, a single compact chassis for 1‐2 bands and a dual chassis for up to 4
bands (Figure 19 ). There are multiple configurations that allow for various power level of amplifiers to be placed into
the chassis. Table 15 shows how the chassis may be configured:
Table 15
Chassis Types

Single chassis
Dual chassis
Low

3‐4
Medium

High
It is possible to have combinations of the above. For example it is possible to build a dual chassis with 2 medium
power bands and 1 high power band in the same remote. Each side of a dual chassis is virtually identical to a single
chassis remote unit. This ensures unparalleled flexibility when building multiple operator / multiple band solutions.
A dual chassis may have 1‐2 fiber optical remote units (FOR). This allows for redundant fiber feeds, multiple‐input
and multiple‐output (MIMO) applications, and dedicated amplifiers.

Remote Unit
All Remote Units have an excellent noise figure, contributing to an overall noise figure for the whole system from
remote to head‐end into the base station of < 3 dB for the RF link.
Both chassis comply with IP65 protection for use in any environment. The durable coating assists in convection
cooling. No fans are used for the Remote Units.
Note: The heat generated by the Remote Units when powered up is used to prevent water ingress into
units. Remote units must remain powered on when mounted outdoors.
Both wall or pole mounting kits are available for chassis mounting.

DMU – Remote head end
Bird's DMU100 series is a compact head end that can function as a low power repeater or BTS interface. The unit can
directly support up to 4 remotes or can fiber feed a Headend Master Unit. Remote access is provided by either the
Bird RGW or via Ethernet connection. The unit is a rugged convection cooled, IP65 chassis designed for outdoor
locations.
It is possible to build the DMU to support more than one band, however, the types of bands and the necessary
duplexers for a configuration must be verified to ensure compatibility with the RGW.
Figure 20
DMU – Remote Head End
In Figure 21, the DMU is used to pick up the signal at a remote location and then it is transmitted on the fiber to
four different locations that need coverage. The RU can be connected to coaxial spreading networks if needed.
Figure 21
DMU Feeding Remote Units



 
In Figure 22, the DMU is feeding a Headend Master Unit which in turn feeds the Remote Units (RU). This is a far
more flexible solution and would be preferred when possible.
Figure 22

The DMU is equipped with a low power uplink amplifier. The unit should be used in a location that has adequate
signal so that power level of a mobile phone will suffice.

System Description
Repeaters
Bird Technologies offers a wide variety of repeaters to boost off air signals. The repeated signals can feed passive
DAS or can be used as an input into the active DAS.
DMR 400 Series Rack Mount Repeater
The DMR 400 is designed to fit in the Headend Master Frame along with the BIU and FOI cards. The system was
originally designed to be used in moving coverage areas such as ships and trains that require active control over the
downlink gain (link symmetry) to compensate for wide variations in the off‐air signals, but the system can easily be
implemented in traditional fixed locations such as offices and hospitals.
Figure 23
DMR 400 Rack Mount Repeater
Although the DMR repeaters are rack mounted with the active DAS components, the DMR repeater can function as
a stand alone unit to provide coverage to a passive DAS.
The DMR repeater family offers link symmetry settings. This function is used to automatically adjust the uplink gain
based on the downlink signal. When installed in moving coverage areas such as trains, the feature prevents the
repeater from desensitizing the donor site by automatically controlling uplink levels.
The DMR repeater also offers self‐oscillation protection. This function is used to detect problems with isolation
between the donor and service antenna. The repeater will intervene and lower the gain to a level equal to the
isolation minus the stability margin. The settings are separate for UL and DL.




On/Off
Stability margin: Value setting of how much lower the gain should be than the calculated isolation. Range of
0.0 to 20.0dBm.
Recovery time: Time that should pass before the repeater reset the gain to the value specified level in “RF
Config” (set gain). Range of 30 to 86,400 seconds.
Recovery margin: Set value of gain level above the gain specified in “RF Config” (set gain) that is used when
the repeater recovers after the “Recovery Time”. Range of 0.0 to 20.0dBm.
The DMR400 offers variable bandwidths up to 35Mhz, depending on the configuration.
Remote access can be provided via an Ethernet connection or through the Bird Remote Gateway. SNMP is a
standard on the units. No proprietary software is required. Operational parameters are set via a web browser.

Fiber Distributed Antenna System (Fiber DAS)
Cable Routing/Antenna Selection
Ensure all cables, e.g. power cable, fiber‐optic cable, Antenna cables are routed and secured in accordance with
local/national requirements while avoiding damage to the cables.
Antennas and coax cables are selected as part of the DAS system design and may vary with location, frequency, and
power level requirements.
Use only authorized and approved antennas, cables and/or coupling devices. The use of unapproved antennas,
cables or coupling devices could cause damage and may be of violation of FCC regulations.
Each individual antenna used with the DAS must be installed to provide the separation distance as specified in the
RF exposure requirements (refer to specific Remote Unit RF Exposure limits in the system description section).
CAUTION
Unauthorized antennas, cables, and/or coupling devices may cause non‐conformity with national or international
regulations, could cause damage, or non‐conforming ERP/EIRP.
Antenna Installation
The Bird Fiber DAS systems do not include remote or head end antenna. The remote end antenna must be selected
during system design, the antenna manufacturer’s data will be required when calculating link budgets.
Antenna installation instructions are provided by the antenna manufacturer.

with optical instruments. Always put the protection caps on unused fibers and receptacles.
Every time a fiber is disconnected and re‐connected care should be taken to avoid getting dust on the connector or
in the receptacle. Clean with a dry fiber cleaning tool before reconnecting the fiber at all times. A single speck of
dust can severely impact the transmission. Do not touch the fiber ends with your fingers. That will leave grease on
the connectors and may cause severe problems.

Installing Headend Equipment
All equipment must be properly grounded. Ground peg in the main connector for both head‐end gear (Master Unit)
and remote gear (Remote Units) must be connected to Phase, Neutral and Ground in a proper way before power is
connected.
The chassis of the remote and the rack of the master unit should be grounded to a potential bar or safety grounding
bar when operated. All electrical installations should be done by a certified electrician only.
BGW
The BGW is designed to be installed in a 19" rack.



The BGW is typically mounted near the top of the rack.
Connect power to an available NEMA5‐15R receptacle.
Using installer provided Ethernet cable, connect the “Ext” port to the appropriate back‐haul connection.
The back‐haul connection can be DSL, off air modem, LAN, WAN. See BGW set up instructions.

Installation guidelines
Master Unit
The Master Unit is designed to be installed in a 19" rack.


Before installing, consider cable routing for all cards to be installed in the Master Unit. The installer may
want to consider horizontal cable managers to be mounted above and below the Master Unit to aid in the
installation and ongoing maintenance of the system.
Each card in the Master Unit will require an Ethernet connection to the BGW in order to be programmed
and monitored. Install contractor provided Ethernet cable between the appropriate Ethernet port and the
Ethernet switch.
Note: The port number on the Master Unit is in reverse order on the back of the Master Unit.


Only the active port on the Master Unit requires an Ethernet connection.
Example: The BIU will consume two slots in the Master Unit. If installed in slots #1 and #2, only
slot #1 will make physical connection to the backplane. Install an Ethernet cable on the back of
the Master Unit in port #1 to provide the BIU with BGW connectivity.

All open slots on the Master Unit require a blank cover plate to allow for proper air circulation. Blank
plates must be ordered separately.

Power Supply Unit
Bird Technologies offers two different power supplies for the Master Unit: AC (DPU‐301) and DC (DPU‐302). The
power supply can be located in a Master Unit other than the one it is powering. Each power supply is shipped with
one Molex power supply jumper. If redundant power supplies are required additional power supply jumper(s) will
need to be ordered.
The power supply uses four slots on the Master Unit.

Prior to installing the PSU in the Master Unit chassis the red slide rails must be carefully removed from the
slots that the PSU will occupy.
Figure 30
Slide Rail Removal
PSU DPU-301
The AC DPU‐301 power supply has a standard C13 receptacle.


The AC DPU‐301 has an input range from 86‐264 VAC with 50 or 60 Hz.
Due to site‐specific needs on length and varying standards of AC plug types, the AC power cord does not
ship with the equipment. The installation contractor must provide the AC power cord.
The DPU‐301 can support a single, fully loaded Master Frame Unit with up to 16 cards (BIU, FOI, ICU). The cards
may be all of one type or a mixture of types.

Backup Power Configuration
It is not required to use a backup/redundant power supply, but if the primary PSU fails a backup PSU will allow the
unit to continue operating without causing an outage.
The system designer may elect to have a single, redundant PSU act as a backup to two different Master Units
simultaneously with the understanding that if the main PSU for each Master Unit fails during the same time period
that the backup/redundant PSU can't support both Master Units.

BIU
CAUTION
Overdriving the RF source input into the BIU will cause permanent equipment failure and will void the warranty.
The installer must ensure that input levels are not exceeded. Plan for maximum power out of the RF source and
attenuate accordingly with external attenuators if needed.
The BIU serves as the RF interface between the RF source and the ICU/FOI. Each BIU is pre‐set to a frequency band
and is not field tunable.
The BIU has two sets of RF source connections. The units can accept two independent feeds (within the same band).
The feeds can be from separate sources or A and B paths in a MIMO configuration.
Due to the high level of RF coming into BIU, use only quality RF cables.

The initial screen for the BIU provides basic information such as name, serial number, part number and active
alarms. The Locate me! button causes an LED to flash on the unit so that the module can be identified in the chassis.
In the left menu, notice the RF 1 and RF 2. The BIU has two RF paths or strips that are correlated to the two RF inputs
on the BIU card. Each RF path has independent settings that can be accessed via the appropriate selection.

Uplink ALC setting for RF path under review. This is the threshold at which
the system will start reducing further gain to prevent increases in uplink RF
to the FOI. After 10dB decrease in gain an uplink alarm will be triggered
Note: Should be left a factory default. Only change if FOR
uplink gain is changed. If gain is increased on FOR uplink
then the same value should be decreased on the ALC.
Example: Changing the UL FOR gain from 12 to 17 would require ALC to be
changed from ‐13 to ‐18.
Hardware ALC offset measured in tenths of a dB. Default setting of 60
(6dBm) should be used for most applications. Should the software not be
able to reduce uplink gain fast enough after the ALC threshold has been
exceed, hardware attenuation will be added to protect the uplink path. In
the example above, the hardware attenuation will trigger at ‐7dBm (‐13dBm

Moving Remotes to Different FOI Port
All DAS components are assigned IP addresses by the BGW. The FOR in the Remote is the assigned an IP address as a
subunit of the FOI to which it is connected. When the Remote is moved to a different FOI one of several actions must
take place:
1. The lease on the Remote IP address must be given time to expire. This could take up to 30 minutes. Once the
current IP lease expires, the new FOI will then assign the correct IP address to the Remote.
2. Manually power cycle the Remote. During the reboot process, the Remote will release the old IP address and
have the correct IP address assigned by the new FOI.
3. Communications to the remote can only occur when the remote has the correct IP address. Before moving the
fiber, access the FOR via the GUI. In the advanced settings, reboot the FOR. As soon as the reboot has been
initiated, quickly move the head end fiber to the new FOI port. When the Remote finishes the rebooting
process, the new FOI will assign the correct IP address.
Replacing Master Unit Cards
All DAS components are assigned IP addresses by the BGW. When a card is replaced, the card must be assigned a
new IP address by the BGW. On rare occasions, the BGW may have not be able to assign an IP address to the new
card. This is easily corrected by removing the card from the Master Unit chassis (with ESD strap attached) and then
re‐install the card. The BGW will then assign the correct IP address.
Moving Master Unit Cards
Occasionally, cards need to be moved to different slots in the Master Unit.
CAUTION
Always use an ESD strap when installation and removing cards. Failure to comply may result
in permanent disabling damage to the module.

Move the card to the new slot.
Ensure there is an Ethernet connection for the new card location on the backplane of the Master Unit.
Wait for the card to complete the boot process. If the card remains in the boot process (Green LED remains on
for approximately 2 seconds and then off for one second) then the IP address may not have been assigned.
Check Ethernet connection.
Log into the GUI to confirm software connectivity. On occasions the card will not show up after being moved.
a. Go to the Configuration menu and remove the card (move from right to left) and then Submit. See
Figure 107 on page 93 .


One laptop for changing the system settings, checking any alarms and status. Only software needed is a
web browser. Operating system can be Windows, Linux or Mac as you prefer.
Spectrum analyzer to measure the uplink. The system relies on test tone measurements in the uplink and
therefore it is important to have equipment to measure them.
SMA tool to be able to connect or disconnect BTS cables from the BIU.
QMA adapter so you can measure signals directly on the head‐end units such as the FOI, BIU, ICU and so
on.

RF Commissioning
In order to make the process more clear for this part of the manual we will consider setting up a fictitious system,
but based on a standard approach at doing Fiber‐DAS. The system that we are considering will have two frequency
bands, let’s assume GSM 900 MHz and UMTS 2100 MHz. The example will have 2 sectors with two remotes in each
sector. Of course your system may look different, be more or less complex but in order to make it clear how the
system is set up this should provide you with a starting point.
Setting up the uplink
Setting up the uplink means to adjust the system for an optimal working point from the antenna port of the Remote
Unit to the actual input on the Radio Base Station. This can be done in different ways depending on how the system
is designed. We will here discuss a standard set‐up starting with a small block schematic showing how the system is
connected.
Figure 133 System Interconnect Diagram
 
  
 
  

 
  



 

  
 






The main parameter that we will be discussing is the ”net gain” of the system. This means the total change in signal
from the Remote Unit antenna port to the receiver port on the base station. There are different ways of setting this
system up but we will look at a 0 dB net gain system which is a good starting point for most systems.
The system gain can be calculated as the gain in the Remote Unit – Loss on fiber + FOI gain – ICU loss + BIU gain –
coupler loss. Basically this takes form of a link budget and here is an example:
Table 68 Example Link Budget
Unit/Component
Remote Unit (RU)

Accumulated Gain/Loss (dB)

Basically this means that whatever is input at the antenna will also be seen at the same level for the Radio Base
Station receiver. This is not a bad starting point but does not take into account the noise load on the base station
which will increase somewhat with this setup.
109
RF Commissioning
Noise load on Radio Base Station
The system will inevitably add some noise to the receiver. When properly set up the noise figure in a system like this
will be better than 3 dB. However, if the gain is improperly set up (i.e. not enough gain in the remote, too much gain
in the head‐end) it is possible to create a very bad noise figure. In order to avoid this the Fiber‐DAS Calculator should
be used to calculate the noise figure of the system in the uplink.
If you have not familiarized yourself with the Fiber‐DAS Calculator, do so before moving on in this manual. The
figures in the Fiber‐DAS calculator relate to the settings of all steps in the chain. By using the calculator, you can
determine the proper settings once you know the fiber loss between the Remote Unit and the headend.
Let us assume your have arrived at a Noise Figure (NF) of 3 dB for this chain. However your system may contain
more remotes, perhaps connected like the system in Figure 134.
Figure 134 Multiple RU Connection Diagram
 
  
  
 
  
 








!
 

 






  

Now the noise load can be calculated by adding the noise contribution from each step of the chain. Below is an
example of noise figures from each of the remotes:

Add your figures to the sheet in the Fiber‐DAS calculator and it will calculate it for you.

Fiber Distributed Antenna System (Fiber DAS)
What we see here is that if we set the system up in this fashion we will desensitize the base station with about 5,5
dB. This can be okay if the base station coverage is only through the Fiber‐DAS system but if the base station is also
being used for outdoor coverage it is not good. We need to change the net gain to reflect this. In general we should
lower the gain so that we desensitize the BTS only about 3 dB. This value is a good compromise and similar to adding
a second antenna to the same receiver port (which is kind of what we are doing with the Fiber‐DAS).
Here are the new values:

As you can see we should set the system up with a net gain of about ‐5 dB. Going back to the settings we had before
which was:

We only need to change the BIU setting using the attenuators in the BIU to lower the gain with 5 dB. This will
accomplish what we need to do and the uplink should then be commissioned.
111
RF Commissioning
Practical approach
Now that we know what we should have we can easily set the system up. You need a spectrum analyzer to do this
and it is easiest to connect it into the BIU port. Remember that when you measure here, the signal should also go
through the BTS coupler before it reaches the base station receiver port. Therefore you should expect to read a
value that is
Your expected gain + the loss in your coupler
If you want a net gain of ‐5 dB and you have a 15 dB coupler, you should read a net gain of +10 on the BIU port. This
is now what we are going to use in the following example.

Turn on the RF
Connect to the BIU and turn on the RF. Set the attenuator in the medium range for the uplink that you are
measuring. This allows you later to adjust it up and down as necessary to get the correct gain for the uplink chain.
Setting them to 10 dB is a good idea. DL supervision can be left as is for now and also DL attenuation which we will
set up later.
Connect to the FOI card and select Opto and RF – RF Config and set it up according to your Fiber‐DAS calculator
settings. Do not forget to turn RF on.
112
Fiber Distributed Antenna System (Fiber DAS)
Next step is to connect to the remote unit and set it up for test measurement in the uplink.
In this screen you should also turn RF on, set the gain to about 35 dB as a starting point and then turn on the uplink
test tone. Note the frequency of the test tone, this is the frequency you should be measuring on your spectrum
analyzer.
113
RF Commissioning
Turn on the spectrum analyzer, make sure it is connected to the right port on the right BIU and then find the
frequency. A reasonable span is 1 MHz and the receiver band width can be set to 30 kHz or similar. Use the marker to
measure the peak of the signal. Then go to the next screen on the remote unit, the RF Status screen.
What we are looking for here is the Test tone Level. Note this down as well, next to the frequency of the test tone
you noted earlier.
CAUTION
Turn Off Test Tone
Do not forget to turn off the test tone when you are done with your uplink. Better check one extra time. They will
otherwise interfere with the normal operation of the system by causing noise to the base station.
Then check your spectrum analyzer. Assuming your test tone level is ‐62,6 dBm as in this example your spectrum
analyzer may show ‐58,2 dBm. Calculating the net gain between the RU and the BIU will then yield ‐58,2 ‐ ‐62,5 = 4,3
dB. Subtract the coupler between the BIU and the radio base station which in this example was 15 dB and we get ‐
19,3 dB as our net gain.
We wanted ‐10 dB so we have 9,3 dB too low gain. We should then increase the gain and the best place to do this
would be in the remote unit by setting the gain at 35 + 9,3 = 44,3 which we will round to 44 dB.
That uplink is now finished and we will repeat the settings for all of our uplink, one at a time.
