WFDS User Manual 1 System Description 1.1 Topology of Distribution System Solution based on WFDS The typical topology of distribution system solution based on WFDS is as shown in Figure 1 Figure 1 Topology of WFDS The solution can divided into several parts, signal source, point of interface and WFDS as the distribution system. For downlink signal the point of interface gets the signal from several BTSs and data equipment, then combines them into one signal and feeds Main Unit.

WFDS User Manual 2 WFDS Remote Units 2.1 About This Chapter This chapter consists of the following sections: 2.2 z The compendium of function z Principle of Work and Specifications z Application of RU z RU Installation and Power Supply The compendium of function The remote unit is an active transceiver which connects the expansion unit or the main unit. RU is the last step in the entire system, and it takes a very important part in the whole system, that is amplifying.
WFDS User Manual UL: RU receives RF signal from antenna UL transmitted from coaxial cable. Signal is enlarged by low noise amplifier then transmitted by optical modules. And at last optical signal is sent to expansion unit or main unit. The power of the RU is supplied by upper unit. 2.3.2 RU Specifications Single Mode Remote Unit Specification Working frequency （MHz） Description UMTS 2100MHz: UL1710-1755, DL2110-2155 DL output RF power（dBm） 21 Noise Figure（dB） ≤4.
WFDS User Manual 2.4 Application of RU 2.4.1 Function The function of DL power amplifier, UL low noise amplifier, DL Optical and Electric Transmitted, UL Electric and Optical transmitted, DGC in UL and DL, digital AGC in UL and DL, System Gain Retrieve Realize the highest power output by local and remote ALC adjustment. UL and DL AGC, ALC controller (and output power) and UL DL switch. 2.4.2 Equipment Ports RF Port：N-F（Connect the antenna） Light Port：FC-APC Local Monitoring Port：RS-232 2.
WFDS User Manual Figure 2 Fixing RU Step2: Connect relative connectors and ports. DC power input here is the DC power supplying for RU, which is supplied by Remote Power Supply. Indicators will show the working status of RU. The DL and UL optical ports are for optical signal from EU or MU. TELESTONE Proprietary © 2009 TELESTONE. All rights reserved.
WFDS User Manual The RF port is in the rear side of cabinet. Figure 3 2.5.2 RU connector EU and RU Address Setting EU Address Setting: Switch dip down means ON The Address of MU does not need to be set The left side of Address from 1-4 dips mean: Each dip shows the cascaded degree of EU. For example, if the dip 1 is on, it means the current EU is placed in the 1st – degree of cascaded connection. If the dip 2 is on, it means the current EU is placed in 2nd – degree of cascaded connection.
