PURPOSE: A two-path optical relaying device of a mobile communication system is provided to satisfy a frequency allocation(FA) increase request of an optical repeater relating to an FA increase request of a mobile communication base station, by using two high power amplifiers(HPAs) in a forward link and a reverse link, so as to manage a low power amplifier(LPA) receiving matter caused when an optical repeater FA is designed. CONSTITUTION: A master optical repeater(10) comprises as follows. A master transmission frequency processor(20) receives many channels from a base station to process the channels. A combiner(C1) combines data processed in the master transmission frequency processor(20). An optical module(O1) converts a signal transmitted from a slave optical repeater into a radio frequency(RF) signal. A splitter(S2) branches an RF signal of the slave optical repeater. A master receiving frequency processor(30) processes a receiving frequency through the channels, and transmits the processed frequency. The slave optical repeater comprises as follows. The second optical module receives data combined in a combiner, and converts the data into an optical signal. A splitter branches a RF signal outputted from the second optical module. A slave transmission frequency processor processes the branched RF signal. The first and the second duplexer filter signals received from a terminal. A slave receiving frequency processor inputs signals of the first and the second duplexer, and processes receiving frequency signals. The second combiner combines data processed in the slave receiving frequency processor.
