System Description

1.1 Overview

The Zinwave 2700 Distributed Antenna System (DAS) is a simple two-stage fiber-optic

solution comprising a centrally located Hub Unit (HU) and distributed Antenna Units

(AU). The Zinwave 2700 DAS is at present the only available system which provides a

truly wideband solution utilizing multimode fiber (MMF). Zinwave’s technology

approach allows the bandwidth of in situ MMF optic cables to be extended sufficiently

to conduct multiple radio frequency signals, at original carrier frequency, over long

distances.

Figure 1-1: Extended MMF bandwidth using the Zinwave patented technology.

1.2 Key features

o Simple two-stage fiber-optic DAS: one Hub Unit (HU) distributes to eight

Antenna Units (AU)

o Wide frequency range: 370 – 2500 MHz

o Only system to deliver truly broadband solution over multimode fiber (MMF)

o Minimum supported distance of 550 m over OM1, OM2 and OM3 type MMF, in

excess of building wiring standard

Zinwave 2700 DAS – User Manual

Issue 1.2

April 2007

o Minimum supported distance of 2000 m over standard SMF

o Dynamically configurable RF signal distribution

o Electronically adjustable signal levels without the need of manual handling

o Hot-pluggable optical transceivers used in HU

o SNMP and CLI based network management

1.3 Architecture

The 2700 DAS system is built from several basic 8-port systems. Each basic 8-port

system comprises one 2700 HU and up to eight AU. The AU can be wideband (276X

series), band-selective (277X series) or a combination of the two.

Figure 1-2: Schematic of a basic 8-port 2700 system.

Each basic 8-port system can be connected to four radio transceivers (e.g. BTS, BDA,

WLAN access point). The connections are made via simplex connectors. Duplex

connections can be realized through the use of external duplexers. The I/O ports are

wideband and accept signals operating in the range 370 – 2500 MHz.

The HU is equipped with eight ports which accept analogue optical transceivers in the

small form pluggable (SFP) form factor. While following the industry standard, these

analogue SFP transceivers are proprietary to Zinwave. Ports which are not connected

to an AU do not have to be equipped with an SFP module.

The SFP modules are connected to the AU via the optical fiber plant. The maximum

optical link length for MMF is at least 550 m, provided that a special Zinwave patch-

cord is used to connect SFP and AU to the fiber plant.

In the AU the signals in both the uplink and the downlink are amplified, however

without applying any complex signal processing. In the downlink direction the

amplification is required to compensate for the electrical-to-optical (E/O) and optical-

to-electrical (O/E) conversion losses as well as fiber attenuation. In the uplink direction

the amplification is used to optimize the dynamic range of the system. The wideband

AUs (276X series) are equipped with two simplex antenna connectors while the band-

selective AUs (277X series) are equipped with a single duplex antenna connector.

1.3.1 RF Signal Distribution

In the HU a RF signal distribution circuitry is implemented which gives the flexibility to

dynamically adjust the routing of radio transceivers to AU. In its default configuration

the HU routes each electrical I/O port to two adjacent optical ports. By enabling a set

of switches in the circuitry this distribution can be changed to simultaneously route two

electrical I/O ports to four optical ports or to route all four electrical I/O ports to all eight

optical ports.

Figure 1-3: Five different possibilities to distribute the input signals.

1.3.2 Signal Level Control

The Zinwave 2700 DAS implements a two-stage attenuator based approach to signal

level control. All attenuators are electronically switched and do not require manual

handling.

A first set of attenuators is situated in the HU right at the electrical I/O ports. These

attenuators are intended to balance signal power of different services such that each

service covers the same area. A high frequency signal, such as UMTS or WLAN for

example, requires more RF power than a PMR or GSM900 signal for the same

coverage area. In addition these attenuators allow the HU to be connected to a range

of radio transceivers with different output power values. A similar attenuator is

provided in the uplink path which can be adjusted to establish link balance between

the uplink and the downlink of the DAS.

A second set of attenuators is situated in the AU. These attenuators are intended to

adjust the cell size of the specific AU and to compensate for different optical loss

values. In the uplink direction the attenuator is used to trade-off cell size and minimum

coupling loss (MCL).

1.3.3 AU Remote Setup

To simplify installation and maintenance and to enhance security, all AU are controlled

remotely via the HU. This includes setting attenuator values, enabling or disabling

overload protection and reading status and alarm information. Each AU can be

addressed individually. The required routing information for this is obtained by

following the setup-procedure after all units are connected.

1.4 System Components

The Zinwave 2700 DAS consists of HU, SFP modules and wideband or band-selective

AU. Apart from the band-selective AU all components cover the frequency range

370 – 2500 MHz.

1.4.1 Hub Unit (2700)

The Zinwave 2700 HU is a 1U high 19” rack mountable device which distributes four

electrical ports to eight SFP ports. The connection to each of the four possible radio

transceivers is via two simplex RF connectors (female SMA type) located at the back

of the unit. The eight optical ports can be equipped with the Zinwave 2780 SFP optical

transceivers. These transceivers are hot-pluggable.

The HU features a series of LED indicators on the front of the unit, indicating the

status of each optical link and of the whole system. Control and network management

is performed via an SNMP based GUI or via a Command Line Interface (CLI) through

a direct serial (RS232) connection. The HU also acts as a master device when

remotely configuring the attached AU.

1.4.2 SFP optical transceiver (278X)

The Zinwave 278X SFP optical transceiver comprises a directly modulated DFB laser

diode operating at a wavelength of 1.3 µm and a PIN photodiode which is capable of

detecting light at this wavelength. In addition a control circuitry is implemented which

is used for bias control, temperature compensation and status and alarm reporting.

The SFP module can be used to connect to both single mode fiber (SMF) and

multimode fiber (MMF).

The SFP module is designed to the mechanical dimensions specified in the SFP-MSA.

An electronic circuitry ensures that no damage occurs when mistakenly plugging a

digital SFP transceiver into one of the Zinwave SFP ports and vice versa. The SFP is

equipped with an LC duplex connector which requires only half the foot-print of the

traditionally used SC connector.

1.4.3 Wideband Antenna Units (276X series)

The Zinwave 276X series of wideband AU amplify the received optical (downlink) and

wireless (uplink) signals and perform the electrical-optical conversion. The units are

designed to operate in the frequency range 370 – 2500 MHz.

The 2760 AU is equipped with a SFP port which is populated with a 2781 SFP

module.

The 2765 AU has integrated optics connected to a SC duplex connector on the front

panel. Because of the very wide bandwidth of the unit, the AU features two simplex

electrical antenna connectors (female SMA type), one for uplink and one for downlink.

It is recommended that patch antennas are used with this class of AU. These units are

not intended to be connected to omni-directional antennas as they do not provide

sufficient transmit-receive isolation.

The wideband AU are powered via PoE (power over Ethernet) according to the IEEE

802.3af standard. Configuration of the AU is remotely via a 2700 HU. The 276X series

AU are intended for mounting to a wall or a ceiling.

2760 Wideband (370 – 2500 MHz) + 6 dBm

2765 Wideband (370 – 2500 MHz) + 12 dBm

1.4.4 Band-selective Antenna Units (277X series)

The Zinwave 277X series of band-selective AU are designed to operate at certain

combinations of frequency bands only. The 277X AU comprise a 276X wideband AU

together with a single-, dual- or tri-band duplexer. The optical interface is identical to

that of the 276X series AU. However, the 277X AU features only one duplex electrical

antenna connector (female N-type).

Because of the filtering performed in the duplexer, the 277X series AU can be

operated at higher composite powers than the 276X series AU and they also support

installations with omni-directional antennas.

The band-selective AUs are powered via PoE (power over Ethernet) according to the

IEEE 802.3af standard. Configuration of the AU is remotely via a 2700 HU. The 277X

series AUs are intended for mounting to a wall, a ceiling or into a 19” rack.

2778 DCS1800 & UMTS (Europe) + 18 dBm GSM / + 15 dBm WCDMA & CDMA

1.5 Configuration and Control

The 2700DAS can be remotely controlled via an Ethernet interface or locally via a

serial RS232 connection on the Hub Unit. The Ethernet interface supports DHCP. The

AUs are controlled through the HU interface. All settings on the system area

configured through one of these interfaces, there are no manual controls on the 2700

DAS. In addition alarm and status information on a range of system parameters can

be obtained and monitored.

The remote control supports SNMP V2.0. The application ZinConfig provides a

graphical user interface (GUI) for the control via the Ethernet Interface.

The local command line interface (CLI) can be accessed using a terminal application

such as HyperTerminal on a MS Windows based computer. Connection is via a 9 pin

null- modem.

Equipment Description

3.1 2700 Hub Unit

3.1.1 Overview

The HU is a 1U high rack or shelf mountable device with four RF input ports (each port

has two simplex connectors, 1 for downlink and 1 for uplink). The signals are routed

from the RF I/O ports to 8 SFP ports through a dynamically configurable distribution

circuit. In addition the signal amplitudes can be adjusted using 8 controllable

attenuators (4 in the downlink and 4 in the uplink direction). A block diagram of the HU

is shown in Figure 3-1.

Figure 3-1: Block diagram of the 2700 HU.

3.1.2 Dimensions and Weight

o 1 × Hub Unit

o 2 × 19” rack mounting brackets (including screws)

o 4 × M6 screws for rack-mounting

o 4 × Rubber feet for shelf mount

o 1 × IEC mains cable

The HU can be mounted into a standard 19” equipment rack using the supplied rack

mounting brackets. Mount the Hub onto the rack in the assigned equipment cabinet

using the four screws supplied (Figure 3-4). If the Hub is shelf mounted ensure that

the rubber feet supplied are in place to prevent blocking the ventilation holes on the

underside.

Figure 3-4: Hub Unit mounted into a 19” equipment rack.

CAUTION For sufficient air circulation, ensure a top and bottom clearance of 25 mm (1 “) to any

other equipment.

3.1.4.2 Connecting the mains cable

The specifications of the power supply unit (PSU) of the HU are listed in Table 3-4.

Ensure that the ON/OFF switch is in the OFF (O) position before connecting the IEC

mains cable to the Hub (Figure 3-5). Plug the mains cable into an outlet providing AC

power with a voltage of 100 – 240 VAC and a frequency of 47 – 63 Hz.

The 2700 DAS can be controlled locally via the serial port or remotely via the network

interface (Figure 3-6). For details on controlling the 2700 DAS refer Chapter 4 of this

guide. To attach the required cables to the Hub Unit follow these steps:

o Serial Port: The serial interface connector is a 9 pin sub-D male connector. To

connect the HU directly to a computer, use a RS 232 null modem. Connect the

RS232 cable to the serial connector, hand tightening the screws to prevent the

connector from loosening.

o Ethernet Port: Connect the Ethernet port of the HU to your network using a

RJ45 category 5e patch cable. For further details on how to configure the

network interface refer to section 4.3.4.1 of this guide.

CAUTION Before connecting the Ethernet port of the hub unit make sure that the network

parameters (IP address, subnet mask, and gateway) on the HU are properly set.

Failure to do so may affect the performance of the network. Contact your network

administrator if necessary, for valid parameters.

Figure 3-6: Connection of the RS232 null modem and the RJ45 Ethernet cable.

3.1.4.4 Connecting the RF transceiver

Connection of the RF signal sources (e.g. BDA, BTS, WLAN access point) is via a pair

of simplex SMF-female connectors per RF port. The ports are labeled 1 to 4 for

connecting up to four RF transceivers. Connect the ports labeled “IN” to the transmit

port of the RF transceiver (= downlink). Connect the ports labeled “OUT” to the

receive ports of the RF transceivers (= uplink).

Figure 3-7: Connecting a pair of jumper leads from a RF transceiver.

As the 2700 DAS is a broadband system, the connections to the RF transceivers are

via simplex connectors. In cases where the RF transceiver has a common duplex

connector for uplink and downlink the signals traveling in opposite direction need to be

separated. This is done with an external duplexer or circulator.

For a larger system with more than eight AU, the RF signals have to be routed to

several hubs. This is achieved by inserting a passive splitting/combining circuitry.

CAUTION When connecting to the SMA connector on the Hub, DO NOT over tighten the

connector. Use a dedicated torque wrench pre-set to 0.8 to 1.1 Nm. If a torque wrench

is not available, firmly hand-tightening the connector is adequate.

CAUTION In the US and Canada, only the use of the Cisco® Aironet ®1200 WLAN access point

(Model AIR-AP1231-A-K9) is approved for connection to the 2700 Hub Unit for

providing WLAN services.

3.2 2780/2781 SFP module

3.2.1 Overview

The 2780/2781 small form-factor pluggable (SFP) modules are broadband

components (350-2700MHz) converting electrical to optical signals (Transmit) and

optical to electrical signals (Receive). A block diagram of the SFP module is shown in

Figure 3-8.

Figure 3-8: Block diagram of the 2780/2781 SFP module.

The electrical input signal is amplified before it is modulated onto the optical carrier

wave. The optical input signal is directly routed to the electrical connector. A micro

controller is included for control and monitoring purpose.

The 2780 SFP is designed to be used in the 2700 Hub Unit. The 2781 SFP is

designed to be used in the 2760 Antenna Unit. While the modules are identical in their

design they differ in the rated operating temperature range.

CAUTION Electrostatic discharge (ESD) preventative measures (i.e. wrist straps, use of ESD

protective bags) should be taken when storing, transporting and handling SFPs as

voltages in excess of 50V can cause damage to the device.

NOTE The 2780 and 2781 SFP have an identical form factor. Make sure to insert the 2780

only in the 2700 HU and the 2781 only in the 2760 AU.

3.2.2 Dimensions and Weight

The physical design of the 2780/2781 SFP module follows the design of standard

digital SFP transceivers as outlined in the SFP Multi-Source Agreement (MSA).

3.2.3 Ports

3.2.3.1 Electrical port

The electrical connection of the SFP is via a push-fit 20-pin connector located at the

rear of the module.

3.2.3.2 Optical port

The optical port on the SFP module is LC duplex (according to IEC 61754-20).

Looking from the front, the optical transmit port is on the left hand side and the optical

receive port is on the right hand side.

WARNING Optical emission can damage your eye-sight. DO NOT look directly into the transmit

port of an active SFP module.

3.2.4 Installation

The SFP is a hot pluggable module. To install the SFP in the HU or the AU, the unit

does NOT need to be powered down. The remaining system remains completely

operational and unaffected by plugging or un-plugging a module into an SFP port.

To insert the SFP, hold the

module by the metal body and

slide it into the designated HU/AU

port. An audible click can be

heard when the SFP is fully

latched. Ensure that the de-latch

bail is in the upright position (this

prevents accidental unlatching of

the module).

Figure 3-9: Picture of fully latched SFP module.

Removal of the SFP is achieved

by extending the de-latch bail and

pulling it away from the unit.

3.3 2760 + 2765 Antenna Unit – Wideband

3.3.1 Overview

o The 2760/2765 AUs are small wall- or ceiling mountable units which amplify the

received optical signals for transmission over a wireless link (in the case of the

downlink signals) and amplify the received wireless signals for transmission

over the optical link (in the case of the uplink signals).

o The 2760 AU utilizes the 2781 SFP optical transceiver for the electrical-optical

signal conversion. The 2765 AU utilizes an integrated optical transceiver which

is not pluggable.

o Because of the wide bandwidth of the units (370 – 2500 MHz) separate

wideband antennas are required for Transmit and Receive.

o Adjustable gain settings allow you to define the coverage area of each AU

individually. Control of the AU is remotely via the HU. These are controlled

remotely via the Hub Unit.

o The 2760 AU can be powered via a 48 V DC supply or Power-over-Ethernet

(PoE). The 2765 is powered only via PoE.

Figure 3-11 and Figure 3-12 show a block diagram of the 2760 and 2765 AU,

3.4 277X Antenna Unit – Band specific

3.4.1 Overview

o The 277X AUs are 3U high wall, ceiling or rack mountable units which amplify

the received optical signals for transmission over a wireless link (in the case of

the downlink signals) and amplify the received wireless signals for transmission

over the optical link (in the case of the uplink signals).

o The 277X AUs utilize the 2765 wideband AU in its core together with a band-

specific duplexer to suppress undesired frequency bands.

o Because of the integrated duplexer, a single antenna is required for both

transmit and receive.

o Adjustable gain settings allow you to define the coverage area of each AU

individually. Control of the AU is remotely via the HU. These are controlled

remotely via the Hub Unit.

o The 277X AUs are powered via IEEE 802.3af compliant Power over Ethernet

surface. Alternatively the AU can be installed in a 19” equipment rack using the

optional mounting kit.

For ceiling or wall mounting, chose the Antenna Unit position following these

guidelines:

o Mount the Antenna Unit as close as possible to the relevant antenna such that

the minimum length of coaxial cable is required to connect the AU to the

antenna. Excessive coaxial cable lengths will reduce the available signal power

and increase the uplink noise figure.

o Allow space above and below the unit for adequate ventilation and to

accommodate the minimum bend radius for the coaxial and fiber cables

Zinwave 2700 DAS – User Manual

Issue 1.2

o The position of the Antenna Unit should provide sufficient air circulation

For mounting in a 19” equipment rack, chose the Antenna Unit position following these

guidelines:

o Locate free space in the rack of 3U height

o Use a location which allows for minimum coaxial cable length to connect the

antenna

Follow the following steps to mount the AU in a 19” equipment rack using the rack

mounting kit (optional)

o Attach the 277X AU to the shelf using the 4 provided screws.

o Place the shelf into the rack and secure with the 4 provided screws

3.4.4.3 Connecting the Antenna to the AU

Connect the antenna to the AU, using low loss coaxial cables. If the antenna cable is

terminated with a connector other than N-type (male) on the AU end, use an

appropriate connector adaptor.

When connecting an N-type connector, firmly hand-tightening is adequate.

Figure 3-24: Connecting the antenna cable to the 277X AU.

3.4.4.4 Connecting the Optical Fiber

o When using MMF, connect the 277X AU to the fiber-infrastructure using the

special Zinwave patch-cord. Connecting to the fiber-infrastructure without the

special patch-cord will lead to a poor quality optical link and reduced maximum

transmission distance.

o Connect the patch-cord end with the SMF (yellow) and MMF (orange or grey)

cords to the AU. Connect the patch-cord end with the two MMF (both cables

either orange or grey) cords to the fiber infrastructure.

o The SC connectors are keyed with a slot and will thus only fit in one (i.e. the

correct) direction.

o Insert the SC duplex connector into the optical I/O port on the AU and press it

firmly into place, making sure that both sides of the connector are securely

latched (indicated by a “clicking” sound)

Zinwave 2700 DAS – User Manual

April 2007

Follow these guidelines when using fiber-optic cabling:

o Do not remove the dust-caps on both the equipment and the optical fiber until

required – they’re there for a reason

o Before connecting, clean the facet of the connectors with a lint-free tissue

o Always make sure that all optical connectors are securely latched

o Do not bend the optical fiber below a radius of 3 cm

NOTE Failure do follow these guidelines may result in a poor quality optical link or in a

complete link failure

Figure 3-25: Connecting the fiber-optic cable to the 277X AU.

3.4.4.5 Connecting the Power Supply Unit

o Using the IEEE 802.3af PoE protocol the PoE injector can be connected to the

Antenna Unit with a Cat5 Ethernet cable of up to 100 m length. This can be

beneficial in situations where it is difficult to provide AC power near the Antenna

Unit location

o Install the PSU in a suited location, making sure that adequate air circulation is

provided.

o Connect the Cat5 Ethernet cable to the connector labeled “To Network Jack” on

the PoE injector.

o Connect the other end of the Ethernet cable to the RJ45 connector on the

Antenna Unit.

4.3.4 Controlling the HU (2700)

Commands to control the HU are typed directly into the HyperTerminal application

window as listed in Table 4-2.

4.3.4.1 Configuring the network interface manually

Setup the network interface of the HU using the “config” command. Make sure that

the subnet mask matches that of your network and that the IP address is not already

assigned to another device.

EXAMPLE To configure the network interface with an IP address of 10.10.10.2, a subnet-mask of

255.255.255.0 and a gateway address of 10.10.10.1 use the following commands:

“config ip 10.10.10.2”

“config netmask 255.255.255.0”

“config gateway 10.10.10.1”.

Zinwave 2700 DAS – User Manual

Issue 1.2

April 2007

4.3.4.2 Configuring the network interface via DHCP

The network interface can be configured to obtain the relevant parameters via DHCP

(Dynamic Host Configuration Protocol). DHCP is enabled by setting the IP address of

the HU to 0.0.0.0. This will cause the HU to request IP address, subnet mask and

gateway address from a DHCP server.

4.3.4.3 Configuring Communities

Communities define the user groups for SNMP with read-only access to the system or

with read-write access. Define these communities using the “config” command.

EXAMPLE To designate the read-only community “readonly” and the read-write community

“readwrite” use the following commands:

“CONFIG R_COMMUNITY readonly”

“config RW_COMMUNITY readwrite”.

4.3.4.4 Setting the Signal Distribution

The routing of the RF signals in the HU is controlled via the commands “dc22” and

“dc44”. As described in section 4.2.6, five different routing combinations are possible.

The command “dc22 1” addresses the switch combining RF ports 1 & 2 onto the SFP

ports 1 – 4. The command “dc22 2” addresses the switch combining RF ports 2 & 3

onto the SFP ports 5 – 8.The command “dc44” addresses the switch coupling the two

other switches in order to combine all four RF ports onto all eight SFP ports. The

commands required to set all viable distributions are listed in Table 4-6.

Table 4-6: Setting the RF distribution.

Distribution Command 1 Command 2 Command 3

1x2 / 1x2 / 1x2 / 1x2 dc22 1 0 dc22 2 0 dc44 0

2x4 / 1x2 / 1x2 dc22 1 1 dc22 2 0 dc44 0

1x2 / 1x2 / 2x4 dc22 1 0 dc22 2 1 dc44 0

2x4 / 2x4 dc22 1 1 dc22 2 1 dc44 0

4x8 dc22 1 1 dc22 2 1 dc44 1

EXAMPLE The three commands “dc22 1 1”, “dc22 2 1” and “dc44 1” entered sequentially

set the HU to full distribution where all input RF signals are present at all eight SFP

ports.

4.3.4.5 Setting the Attenuator Values in the Hub Unit

The attenuators in the HU are controlled using the “DLIA” (DownLink Input Attenuator)

and the “ULOA” (UpLink Output Attenuator) commands for the downlink and the uplink,

respectively. The first parameter selects the RF I/O while the second parameter

specifies the required attenuation value.

EXAMPLE The commands “uloa 2 15” sets the uplink output attenuator of RF I/O # 2 to 15dB.

Zinwave 2700 DAS – User Manual

Issue 1.2

April 2007

4.3.5 Enabling Communication to Antenna Units

4.3.5.1 Auto configuration

In order to be able to communicate with the attached AUs, the HU requires information

on their unique identifiers (MID-numbers). This information is collected via the

command “discover”.

NOTE Control of the attached AUs is not possible without first running the discover

command.

4.3.5.2 Manually adding AUs

If for some reason the “discover” command is not executed successfully the AUs

can be manually added to the system configuration. For this you need the unique

identifier of the AU, the MID number. This is an 8-digit hexadecimal (0-9, A-F) number

and can be found on the AU label. The AU is added using the “+addau” command.

EXAMPLE The command “+addau 1 10F54D9A” adds the AU with the MID 10F54D9A to the

SFP port 1.

Adding the same AU to another SFP port deletes the old entry. Multiple entries of the

same MID are not possible.

4.3.6 Controlling the AU (276X and 277X)

Commands proceeded by ++ are Antenna Unit commands and routed to the currently

active AU. AUs are activated using the REID command. On activating a new AU its

current settings are displayed.

EXAMPLE The command “reid au3” activates the AU connected to the SFP port # 3. All

commands proceeded by “++” are now directed to this AU.

4.3.6.1 Setting the Attenuator Values in the Antenna Unit

The attenuators in the AU are controlled using the “++dla” (DownLink Attenuator) and

the “++ula” (UpLink Attenuator) commands for the downlink and the uplink,

respectively. Before using this command, make sure that the correct AU is active.

EXAMPLE To set the attenuation of the AU which is connected to SFP port # 7 to 3 dB, the AU

has to be activated using the command “reid au7”. Then the attenuation setting can

be changed using the command “++dla 3”.
