Abstract
Provided is an optical communication system having an aggregate station at a head and a plurality of extension stations connected in series. The aggregate station outputs a downlink optical signal generated by performing electrical-to-optical (E/O) conversion for a radio signal to the plurality of extension stations and acquires radio signals by performing optical-to-electrical (O/E) conversion for uplink optical signals input from the plurality of extension stations. Each extension station transmits a radio signal obtained by performing O/E conversion for the downlink optical signal received from the aggregate station and transmits an uplink optical signal generated by performing E/O conversion for a received radio signal to the aggregate station. Wavelengths of the uplink optical signal and the downlink optical signal allocated to the plurality of extension stations are the same.
