Topology of Distribution System Solution based on WFDS The typical topology of distribution system solution based on WFDS is as shown in 0 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. Main Unit converts it into optical signal and distributes the signal to Expansion Unit and Remote Unit. The Remote Unit transfers the signal into radio frequency and outputs to the antenna. At each Remote Unit, the operator can set the gain for each system such as GSM, CDMA and 3G independently, wh ich optimizes the covera ge for each system and makes future adjustment convenient. 2.

All rights reserved. 4 2.2. 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. RU receives UL fiber optical signal, then it transmitted into the optical module and transform the optical signal into electric signal, after enlargement, it send by the external connection antenna; in a similar way, equipment receives uplink RF signal by the external connection antenna, and amplified in uplink then input to the optical module. Then output the fiber optical signal to the EU (or MU) after the optical module transform the electrical signal to the optical signal. 2.3. Principle of Work and Specifications 2.3.1. Principle of Work The equipment includes the optical module, UL amplifier, DL amplifier, duplexer, monitoring unit and power supplier. DL: RU receives the DL fiber optical signal from the expansion unit or the main unit, then the optical module transmits the optical signal into RF signal. After amplifying, the signal is sent through coaxial cable by the RF antenna. 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. Meanwhile, RU can receive setting and inquiring information from Expansion and Main Unit. 2.3.2.
