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 0 ETL LTE 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 om several BTSs BTSs,and data equipment, then combines them into one signal and feeds Main Unit.
User Manual 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.

User Manual RF port 1 RF antenna port，transmitting/receiving signals to/from distributed antenna. This RF antenna port is a duplexed N-F connectors. The port can be connected to the antenna or through RF jumper cables and splitters to more antennas. Optical port DL optical port: receiving DL optical signal from EU/MU. UL optical port: transmitting UL optical signal to EU/MU. LED indicators Power status: The green LED describes the power supply status. If the indicator is off, RU is not power off.
User Manual Power supply connector This port is used to power RU. Voltage range is 40~70 V DC. Type voltage is 48V DC. RU can get DC power from EU thought power supply fiber cables. Remote power supply distance can reach to 300 m, using 1 mm2 power cable. 2.4. RU Installation Installation Mode: Wall /Ceiling mounted.。 RU Installation 1. Drill the wall to install the four M6 screw anchors according to the layout show in figure 4. You can choose to install the terminal box conveniently close to the RU. 2.
