US Patent 7650079 Integrated optical transceiver circuit

An integrated transceiver contains a optical equalizer for a distorted O/E-converted signal, an adaptive regenerator coupled to the equalizer, and a clock recovery circuit coupled to the adaptive regenerator. The transceiver has further an embedded processing unit and an integrated programmable memory which stores software program. The processing unit is coupled to adjust threshold values of the adaptive regenerator according to a software algorithm loaded into the memory.
