Abstract:
1. An optoelectronic module, comprising: an optical receiver configured to receive an optical signal and generate an electrical data signal corresponding to the optical signal; a post-amplifier electrically connected to the optical receiver and configured to amplify the electrical data signal; and a retiming circuit configured to quantify a quality of the optical signal from which the amplified electrical data signal is derived, the retiming circuit including a main channel decision circuit and an error channel decision circuit both configured to receive the amplified electrical data signal output by the post-amplifier and to receive a clock signal, the retiming circuit further including a first shift register connected to an output of the main channel decision circuit, a second shift register connected to an output of the error channel decision circuit, and an exclusive OR circuit connected to outputs of the first shift register and the second shift register.
