Abstract
A wired relay method for using a remote station and an apparatus thereof for a Radio over Fiber (RoF) wired relay system supporting a Time Division Duplexing (TDD) wireless communication service, which shares an Low-Noise Amplifier (LNA) for both uplink and downlink operations. The remote station includes a block for dividing each of a downlink optical signal carrying service data and an optical signal carrying transmission/reception control information of the RoF wired relay system, which are input from a base station, a gain controller for separating an uplink Radio Frequency (RF) signal input from an antenna or a portion of a downlink RF signal output from a High-Power Amplifier (HPA) and for monitoring the strength of the input and output RF signals in order to control a gain of the LNA. A converter mutually converts an optical signal and an RF signal, an amplifier amplifies the converted RF signal, and an RF signal flow controller automatically controls uplink and downlink transmission paths of the amplified RF signal according to a transmission/reception status of the RoF wired relay system.
