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.

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

ADCP-75-348 • Issue 1 • 04/2008 4.1 Wavelength Division Multiplexer System 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. Both the host unit WDM module and the RU WDM module consist of a bi-directional wavelength division multiplexer.

ADCP-75-348 • Issue 1 • 04/2008 6.3 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.
ADCP-75-348 • Issue 1 • 04/2008 6.4 WDM Host Module Mounting Shelf and WDM Host Module Installation Procedure A bi-directional wavelength division multiplexer (WDM) system is available as an accessory item for the URH system. If the application does not require the use of a WDM system, skip this section and proceed to Section 6.5. The WDM host module mounting shelf installs in the equipment rack with the HU.
ADCP-75-348 • Issue 1 • 04/2008 1. The WDM host module mounting shelf is shipped with the mounting brackets installed for 23-inch rack installations. If installing the mounting shelf in a 23-inch rack, proceed to Step 4. If installing the mounting shelf in a 19-inch rack proceed to Step 2. 2. Remove both mounting brackets from the mounting shelf (requires Phillips screwdriver) and save screws for reuse. 3.
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.
ADCP-75-348 • Issue 1 • 04/2008 6. Back out the HU mounting screws just enough to provide clearance for installation of the cable guides. 7. Slide each cable guide into position for installation and then securely tighten the corresponding mounting screws. 6.6 Chassis Ground Connection A stud is provided on the rear side of the chassis for connecting a grounding wire to the chassis.
ADCP-75-348 • Issue 1 • 04/2008 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.
ADCP-75-348 • Issue 1 • 04/2008 22411-A Figure 12. Forward and Reverse Path Coaxial Cable Connections 6.8 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.
