Classification: CPC H | IPC H

Claim 12:
13. The optical communication system according to claim 11, wherein the processing circuitry of the second optical transceiver functions as:
a first optical transceiver unit to transmit a first transmission signal; and
a second optical transceiver unit to transmit a second transmission signal,
wherein as at least one of the first optical transceiver unit and the second optical transceiver unit, the processing circuitry calculates the bandwidth, and
calculates an optical signal-to-noise ratio of the test signals received by the test signal receiver, wherein
the processing circuitry of the second optical transceiver determines modulation rates of respective two transmission signals being the first transmission signal and the second transmission signal, modulation levels of the respective two transmission signals, and subcarrier spacing between the two transmission signals, depending on each of the bandwidth and the optical signal-to-noise ratio.
