Patent ID: 6909848

Claim:
A bit rate transducer in an optical transmission system, comprising: a demultiplexer for demultiplexing optical signals into different wavelength channels; a plurality of bit rate receivers, each bit rate receiver coupled to an output of said demultiplexer for converting a demultiplexed optical signal into a corresponding electrical signal and for generating a bit-rate error signal, said bit rate receiver having a sensing means for generating a temperature reference signal, a detecting section coupled to outputs of said demultiplexer for generating signals indicative of the bit rates of the optical signals outputted from said demultiplexer; and, a controller for comparing each bit rate detected by said detecting section with a predetermined data to generate a control signal that is used to adjust the bit rate of one of the bit rate receivers, wherein said controller compares each bit rate detected by said detecting section in response to one of the bit-rate error signals and one of the temperature reference signals.
