Provided is an optical transmission system, comprising: a transmission frame generating unit which divides, into a plurality of transmission signals, a transmission frame in which a plurality of client signals is contained; a plurality of sub-carrier transmitting units which, using different optical carriers, converts the plurality of transmission signals into optical signals and transmits the converted optical signals; a plurality of sub-carrier receiving units which receives the transmitted optical signals and converts the optical signals into received signals; a transmission frame terminal unit which combines the received signals and recovers the transmission frame; a time division inverse multiplexing processing unit which time division inverse multiplexes the recovered transmission frame and splits same into the plurality of client signals; and a time slot control unit which determines a new time slot allocation when time division multiplexing the plurality of client signals into the transmission frame, and interrupts the supply of power to the sub-carrier transmitting units and the sub-carrier receiving units which transmit and receive the optical signals to which the client signals have not been allocated. |
