The FlexWave URH Remote Unit interfaces with the Host Unit and performs the optical to
electrical conversions for transport to the antennas. A typical FlexWave URH system consists of
a Host Unit (HU) and a Remote Unit (RU).
The RU is comprised of three RF doors and one common door on a single chassis. The doors are
named left, right and front as viewed from the top of the chassis (Figure 1). The common door is
necessary for all deployments. For normal operating conditions the host DART RF matches the
remote. In simulcast mode the host DART RF matches the remote in the simulcast ratio.
PCS 1900 (Supports only 35 MHz contiguous per door)
• TX: 1930-1990 MHz
• RX: 1850-1910 MHz
SMR/ESMR 800/900 MHZ
• TX: 851-869, 935-940 MHz
• RX: 806-824, 896-901 MHz
RF spectrums may be changed by replacing a door on the RU. Additional RF spectrum options
may be supported through new spectral allocations by means of pluggable RF boards.
The URH Remote Unit, shown in Figure 2, consists of an environmentally-sealed unit and
various electronic modules that are housed within the unit. Excess heat is dissipated using a
passive cooling system which eliminates the need for external cooling fans. Solar shields are
included and installed over the left, right, and front door. The low profile design of the unit
requires minimal real estate for installation. The RU may be mounted on a pole or a flat surface.
Separate antennas (not provided) connect to the RU.
Each RU door is factory configured to order, fully tested assembled and shipped as a single unit
ready for deployment. Three solar shields are included and one must be must be installed over
the left, right, and front door.
A fiber connector cable assembly is provided with 10 meters of environmentally hardened cable
and 1 meter of exposed, un-terminated single-mode 900µm optical fiber sufficient for splicing
in an OSP splice tray.
A power connector cable assembly is provided with 15 feet (4.6 m) of environmentally
hardened cable allowing power junction termination.
The FlexWave RU, supports or provides the following basic functions:
• Provides RF interface (antenna port) for the antennas.
• Accepts AC power input.
• Provides a visual indication of unit status
• Optical backhaul of digitized RF
1.2Primary Components
ADCP-75-347 • Issue 1 • 04/2008
The remote is comprised of three doors and one common door on a common chassis. A bracket
that allows the chassis to pivot is secured to the chassis at the left rear corner. This bracket is
secured to the top and bottom right rear corner of the chassis with two capscrews. The RU doors
are factory configured to order, fully tested assembled and shipped as a single unit ready for
deployment. Three solar shields are included and installed over each door. The RU houses the
electronic assemblies, controls RF emissions, seals out dirt and moisture, and provides passive
cooling. The antenna cable connectors, fiber connectors, AC power connector, and the unit
status indicator are located on the bottom of the unit.
1.3Mounting
The FlexWave URH RU should be mounted on a utility pole, mast, or on a flat surface. A
mounting kit is available for each unit. Installation consists of securing the bracket to the
mounting surface and then hanging the unit from the bracket. The bracket may be attached to a
variety of surfaces such as wood, concrete, or steel. The FlexWave URH RU should be mounted
in a restricted access location only.
1.4Fault Detection and Alarm Reporting
The FlexWave URH RU detects and reports fault and alarm information. RU has a single red
STATUS LED on the bottom. At startup, LED is turned “ON” prior to being controlled by the
SeRF processor. After startup, unique patterns are displayed to show the current status. Tab l e 1
defines the patterns displayed for the different conditions. Different sets of patterns may be
defined based upon a pattern “code”. In this release (Software Version 1.1), the “code” can not
be provisioned and is assumed to be zero. When more than 1 condition exists, the pattern for the
condition with the higher priority is displayed. The highest priority is a “0”, with higher
numeric values having a lower priority. Fault and alarm information is also available using the
FlexWave URH GUI.
The Wavelength Division Multiplexer (WDM) system is an accessory product that is used when
it is desirable or necessary to combine the forward and reverse path optical signals from one
URH system onto a single optical fiber. Each WDM system consists of a host module and a
remote module.
At the HU there is a WDM chassis that contains the WDM modules at the RU the WDM is built
into the fiber patch cord. The WDM system is available as an accessory item.
1.7Antenna Cable Connections
The TX0/RX0 antenna cable connections are through 50-ohm N-type female connectors. The
RU includes an internal duplexer which allows a single antenna cable to carry both forward and
reverse path RF signals between the antenna and the RU. The RX1 diversity antenna cable
connections are through 50-ohm N-type female connectors.
An externally-mounted lightning surge suppressor is available as an accessory. The surge/
antenna connector on the lightning suppressor is an N-type female connector. The URH Remote
Unit must be properly grounded for the lighting surge suppressor to function properly.
ADCP-75-347 • Issue 1 • 04/2008
1.8Powering
The FlexWave URH is powered by 100 to 240 VAC (nominal 120 or 240 VAC), 50 to 60 Hz
power. The AC power is supplied through a 15-foot (4.6m) three-wire power cable that is
provided with the unit. The power cable connects to a mini 3-pin AC power connector mounted
on the bottom of the RU. The power cable is rated for indoor or outdoor use and must not be
placed within electrical conduit as this will impede the cooling of the cable during usage.
The stub end of the power cable must be routed to an external junction box (not provided) for
connection to the AC power source. A circuit breaker rated at 15 Amps (120 VAC) should be
used to provide overcurrent protection for the FlexWave URH power circuit. It is also
recommended that an external AC outlet (not provided) be installed near the FlexWave URH
RU to power test equipment and power tools.
1.9Grounding
A grounding threaded hole (hex socket capscrew and washer provided by installer) is located on
the bottom of the unit for connecting a grounding cable to the unit. A #6 copper wire terminated
with a ring terminal must be provided to link the unit to an earth ground source.
Caution: For proper and safe equipment operation, an approved earth ground connection must
be provided.
1.10 Cooling
Passive cooling of the electronic assemblies is provided by conducting excess heat from the
internal electronic components to the aluminum enclosure. The heat is then dissipated by
radiation to the external fins where convection air flow over the enclosure’s external fins cools
the unit. An alarm is generated if a high temperature condition occurs within the enclosure.
1.11 Lightning Surge Suppressor (Accessory)
An external lightning surge suppressor is available separately for the RU. It is recommended
that a lightning surge suppressor be installed at each antenna port to reduce the chance of
damage to electronic components should a lightning strike occur. The lighting surge suppressor
antenna port is an N-Type female connector.

5INSTALLING REMOTE UNIT ON THE MOUNTING BRACKET
Caution: It is the installer’s responsibility to verify that the wall or pole will support the weight
of the mounting bracket, remote unit with components. The weight of a fully loaded remote unite
is 197 pounds (89.4 kg). Use appropriate means to safely lift and handle the RU during
unpacking and installation.
Warning :
scrapes always wear gloves and appropriate protective clothing when handling the Remote Unit.
Use the following procedure to secure the FlexWave URH RU to the mounting bracket.
1. Hang the RU from the mounting bracket as shown in
2. Place a 3/8-inch flat washer and 3/8-inch flat washer on each hex bolt.
3. Insert a 3/8 x 1-inch hex bolt through each hole in the pivot bracket located at the bottom
4. Thread bolts into mounting bracket and tighten securely.
Cooling fins on the Remote Unit have sharp corners and edges, to prevent cuts and
rear side of the RU fit into the two mounting posts at the top of the mounting bracket.
Review the Remote Unit order to determine the number of DARTs, number of power supplies,
and the number of SFPs. Use this information to find the power consumption for the doors from
Table 5 and Ta ble 6 when used.
Use the following formula to determine the maximum power consumption and then determine
the circuit breaker or fuse to use.
Enter the power consumption in the spaces provided:
Rear door power consumption from Table 5 _________Watts
Front door power consumption from Table 6_________Watts
Additional SFP’s _____ x 1.25 _________Watts
_________ TOTAL POWER CONSUMPTION
To determine the current (Amperes) requirements divide the total Watts by the input Voltage:
Watts
=Amps
Volts
Once you have calculated the current (Amps) draw determine the circuit breaker or fuse size
based on local codes and practices. Circuit breaker or fuse size must be 20 Amps or less.
