EXPANDABLE SYSTEM FOR MOBILE COMMUNICATION OPTICE REPEATER

摘要

An expansion system of an optical repeater for radio communication is provided to realize an additional expanded repeater which comprises functions for signal compensation, high-output power amplification and band-pass filtering of a reverse signal. A main repeater(100) transmits a forward signal from a base station to an additional expanded repeater(200), and combines a reverse signal received from the additional expanded repeater with a reverse signal received from its installation region. The additional expanded repeater performs the high power amplification for the forward signal by using the signal compensation and rated capacity, and then transmits the reverse signal received from its installation region to the main repeater through the filtering and signal compensating processes.
