ADCP-75-348 • Issue 1 • 04/2008 • Preface
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.

ADCP-75-348 • Issue 1 • 04/2008
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.
Figure 1. FlexWave URH Block Diagram
The basic function of the FlexWave URH simulcast (point-to-point) platform is to transport, via
fiber optic cable, RF signals form a Base Transceiver Station (BTS) to multiple antenna interfaces
allowing communication to a mobile device. Up to 8 simulcast remotes are supported.

2 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.
3 HOST UNIT DESCRIPTION
A front view of the HU, shown in
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.
The HU is designed for use within a non-condensing indoor environment such as inside a wiring
closet or controlled environment cabinet. All controls, connectors, and indicators (except the
grounding point) are mounted on the HU front panel. Current versions of the HU allow vertical
cable guides to be installed over the mounting brackets on either side of the HU.

3.1 Mounting
The HU is intended for rack-mount applications. A pair of reversible mounting brackets is
provided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECO
equipment rack. When installed, the front panel of the HU is flush with the front of the rack.
Screws are provided for securing the HU to the equipment rack.
3.2 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.

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
one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6.
information.
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

• 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
ADCP-75-348 • Issue 1 • 04/2008
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
described in Tabl e 2.
