Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times.
These warnings are flagged by use of the triangular alert icon (seen below), and are listed in
descending order of severity of injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.

Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transceiver of any digital unit or exposure to laser radiation may
result. An optical power meter should be used to verify active fibers. A protective cap or hood
MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid
the potential of dangerous amounts of radiation exposure. This practice also prevents dirt
particles from entering the adapter or connector.
Caution: This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot
(91.4 cm) minimum clearance from the antenna while the system is operating. Wherever
possible, shut down the RAN before servicing the antenna.
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails
without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent
or curved to a radius of less than 2 inches (5.1 cm).
Caution: Exterior surfaces of the RU may be hot. Use caution during servicing.

GENERAL
The FlexWave URH product family of products is intended as a “next generation” distributed
antenna system (DAS). DAS products provide bidirectional transport of digitized RF spectrum.
Each link consists of a host unit (providing the interface between the base station RF ports and the
optical fiber) and at least one remote unit (providing the interface between the optical fiber and the
remote antenna). The difference in this product is the high-speed digitalization of a wideband
portion of spectrum, that allows for transport of RF signals over extended distances, without the
RF degradation that normally results when analog systems are impacted by optical effects.
The basic function of the FlexWave URH platform is to transport via fiber optic cable RF
signals form a Base Transceiver Station (BTS) to an antenna interface allowing communication
to a mobile device. Multiple BTS communication paths are allowed over a single URH system.
Diversity receive is supported. A block diagram of the system is shown in Figure 1.

INTRODUCTION
The front access URH Host Unit interfaces with the BTS and performs the analog to digital and
electrical to optical conversions for transport to the URH Remote Units. A typical URH system
consists of a Host Unit (HU) and a Remote Unit (RU).
The HU is designed for maximum RF flexibility to address Carriers changing and evolving
spectrum needs, making the most use of cost efficient resources for serving multiple remotes
such as simulcast architecture and sharing of common functions such as power, control and
management over multiple host units. These features are designed into a compact package that
reduces the amount of overall rack space required within a BTS Hotel. Each host chassis can
support up to eight RUs.
The HU is a three rack-unit high single-unit assembly that mounts in a standard equipment rack.
The RU consists of an outdoor enclosure that houses various electronic components. The RU is
a modular self-contained enclosure. Together the HU and the RU together comprise an URH
system. Various accessory items are also available for use with each system. All items
referenced as “accessory items” are not furnished and must be purchased separately.
HOST UNIT DESCRIPTION
A front view of the HU, shown in Figure 2, consists of an electronic circuit board assembly and a
fan assembly that are mounted within a powder-paint coated sheet metal enclosure. The enclosure
provides a mounting point for the circuit board and fan assembly and controls RF emissions. Fan
assembly can be replaced in the field. Host Unit may be upgraded once it is installed to support
additional URH Remote Units. This can be performed without disrupting service.

SeRF Card
3.2.1
Network Interface Connection
SeRF front panel has an Ethernet port allowing interface communication with the internal
processor and transfer of data to the optical protocol allowing IP transport between the HU and
the remote(s). The network interface allows the HU to be controlled through a network.
Network interface connection between the HU and the network is supported by a RJ-45 jack 10/
100Base-T (IEEE802.3 compliant) with integrated green ACTIVITY and LINK LEDs. The
Ethernet port supports a maximum cable length of 100 meters (328 feet) to a hub or back-toback nodes. CAT5 or better cable should be used when making this connection. The Ethernet
connection should not be connected to an Ethernet circuit used outside the building.

one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6.
2. Pinout information is shown in Table 1. See Figure 3 for RJ45 connector wiring
information.
3.2.3
Optical Interface
Optical connections between the HU SeRF card and the RU are supported through Small Formfactor Pluggable (SFP) transceivers. The optical interfaces are standard single-mode duplex LC
(flat polished UPC). There are 8 duplex optical interfaces, one for each simulcast remote.
3.3
DART Card
The host DART provides the interface between base station equipment and the SeRF. It is a
band specific assembly and exists in the following versions:
• Cellular
• SMR 800
• SMR 900
• PCS
The following features and capabilities are available on the DART Card:
• Amplifies, down-converts, filters and digitizes from a 1.5MHz to 35MHz band of the
incoming RF signal
Page 4

ADCP-75-348 • Issue 1 • 04/2008
• Converts incoming digital signal to analog, filters, amplifies and up-converts
• Provides bi-directional interface between parallel digital RF (to D/A and from A/D) and
Serial RF (SeRF) to/from SeRF board
• Performs digital up/down conversion and adjustable delay processing
• Non-contiguous bands and receive diversity is implemented with multiple DART Cards
3.3.1
RF Signal Connections
The RF signal connections between the HU DART cards and the BTS are supported through
two (FWD RF IN and REV RF OUT) QMA-Type female connectors. One connector is used for
the forward path RF signal. The other connector is used for the reverse path RF signal. In some
installations, it may be necessary to install a Conditioning Panel and/or Duplexing Panel
(accessory items) to support the interface between the HU and the BTS. The HU should be as
close as possible to the BTS to minimize cable losses.
3.4
System Card
The System Interface Card gives additional front panel space for the SeRF card. The System
Card front panel also provides connections for alarm outputs, 10 MHz output, and status LEDs.
This card may be used to provide a 10 MHz clock reference to which the SeRF's Master clock is
frequency locked from the internal crystal oscillator. When the internal clock is not used the
clock can be obtained from an external 10 MHz input.
3.5
Power Supply
HU is powered by a modular DC to DC power supply located on the lower left side of the
chassis. An On/Off switch is provided on the HU power supply module front panel.
HU is powered by ± 20 to ± 60 VDC power (nominal ± 24 or ± 48 VDC), power is fed to the HU
through a connector located on the front of the module. Power to the HU must be supplied
through a fuse panel (available separately). Each HU must be protected with a fuse.
3.6
User Interface
The HU user interface consists of the various connectors, switches, terminals, and LEDs that are
provided on the HU front panel. The HU user interface points are indicated in Figure 4 and
described in Table 2.

OSP Fiber Cable Installation Guidelines
The outside plant (OSP) fiber optic cables should be routed between the HU distribution panel
and RU outside plant cabinet and terminated before the equipment is installed. A diagram of a
typical OSP cable routing is shown in Figure 7. At the HU, the OSP cable should be terminated
at a fiber distribution panel and spliced to pigtails. Jumper patch cords may then be used to link
the HU optical ports to the OSP cable terminations. Whenever possible, a guideway such as the
FiberGuide system should be provided to protect the fiber optic patch cords from damage and to
prevent excessive bending. The procedures for connecting the OSP cable optical fibers to the
HU is provided in Section 6.8.

HU Mounting Procedure
The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both
US standard and metric machine screws are included for rack mounting the HU. When loading
the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous
condition such as a severely unbalanced rack. The rack should safely support the combined
weight of all the equipment it holds. In addition, maximum recommended ambient temperature
for the HU is 55º C (131º F). Allow sufficient air circulation or space between units when the
HU is installed in a multi-rack assembly because the operating ambient temperature of the rack
environment might be greater than room ambient.

ADCP-75-348 • Issue 1 • 04/2008
Warning: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically powered equipment. To prevent electrical shock, never install or
use electrical equipment in a wet location or during a lightning storm.
Note: To insure that all optical connectors remain dust-free during installation, leave all dust
caps and dust protectors in place until directed to remove them for connection.
Use the following procedure to install the HU in the equipment rack:
1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If
mounting the HU in a 19-inch rack, proceed to Step 4. If mounting the HU in a 23-inch

6.7
Coaxial Cable Connections
The RF interface between the HU DART card and the EBTS/BTS is supported through two type
QMA female connectors mounted on each DART front panel. One connector provides the
coaxial cable connection for the forward path (downlink) signal and the other connector
provides the coaxial cable connection for the reverse path (uplink) signal.
In most installations, it is usually necessary to insert an external attenuator into the forward path
link between the HU and the BTS. A signal level that is greater than –9 dBm will overdrive and
possibly damage the HU receiver. Before completing the forward path connection at the BTS,
verify that the composite forward path RF signal level at the HU is between –25 and +5 dBm.
The HU should be mounted as close as possible to the EBTS/BTS to minimize cable losses. Use
the following procedure to route and connect the forward and reverse path coaxial cables to the
HU DART cards:
1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial
communications cable (RG-400 or equivalent) for all coaxial connections.
2. Route the forward and reverse path coaxial cables between the HU and the BTS interface
(per system design plan) and cut to the required length. Allow sufficient slack for dressing
and organizing cables at the HU and for installing an external attenuator in the forward
path link.
3. Terminate each cable with an QMA-Type male connector following the connector
supplier’s recommendations.
4. If required, install an external attenuator in the forward path.
Note: The composite forward path RF signal level at the HU must be between –25 and
+5 dBm. Do not connect the forward path cable until the composite forward path RF
signal level is measured and the amount of external attenuation required is determined.
5. Connect the forward path cable to the FWD RF IN connector on the HU DART front
panel as shown in Figure 12.
6. Connect the reverse path cable to the REV RF OUT connector on the HU DART front
panel (see Figure 12).
7. Repeat this procedure for the remaining DART cards in the HU.
8. Dress and secure cables at the right side of the HU.
9. Complete all remaining coaxial connections as specified in the system design plan.

Optical Connections
The optical interface between the HU and the RU is supported by optical ports. Each optical
port consists of an SFP with LC optical transceivers mounted on the SeRF card front panel.
Each FWD port provides an optical connection for the forward path (downlink) signal. Each
REV port provide an optical connection for the reverse path (uplink) signal. Each REV port can
also provide the optical connection for the diversity reverse path (uplink) signal.
The optical connections are dependent on whether or not a WDM host module (accessory) is
installed:
• If the installation does not include a WDM module, proceed to Section 6.8.1 for the
optical connections procedure.
• If the installation includes a WDM module, proceed to Section 6.8.2 for the optical
connections procedure.
