OPTICAL COMMUNICATION SYSTEM AND METHOD USING MANCHESTER ENCODED SIGNAL RE-MODULATION

摘要

An optical communication system and a method using Manchester encoded signal re-modulation are provided to reduce cost of a communication network and to enhance a transmission characteristic by re-modulating a Manchester encoded downstream signal to use as an upstream signal. An optical communication system includes a transmitting unit, and a receiving unit. The transmitting unit generates and transmits a Manchester encoded optical signal(402) of a first data stream. The receiving unit divides power of the optical signal into two, and modulates one of the divided optical signals based on a second data stream to receive the transmitted optical signal and recover the added second data stream.
