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 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.
