Abstract
A self-healing bit rate transducer in an optical transmission system includes a demultiplexer for demultiplexing optical signals into different wavelength channels; bit rate receivers for converting the demultiplexed optical signals into the corresponding electrical signals, for generating a bit-rate error signal, and for generating a temperature reference signal; a detecting section for generating a signal indicative of the bit rate of the optical signals outputted from the demultiplexer; and a controller for comparing the detected bit rate with a predetermined data to generate a control signal that is used to adjust the bit rate of the respective bit rate receiver.
