Abstract

A control device for optimising the transmission performance of an optical communication system, said control device including an optical detection unit, a comparison unit and a control unit. The optical detection unit is used for adjusting an optical feedback signal from the optical communication system according to a set signal output, so as to generate first and second measurement signals respectively related to one of a bit error rate, a Q factor and a signal-to-noise ratio of the optical feedback signal as adjusted. The comparison unit compares the first and second measurement signals, so as to generate an error signal. The control unit is used for generating the set signal output, and according to the error signal, generating a control signal output used for adjusting an optical signal transmitted by the optical communication system.
