Abstract:
1. A transceiver for use between interconnected high speed fiber optic communication channels, the transceiver comprising: an optical input system having a photo detect and driver circuit which is configured to receive an input signal from an input fiber optic channel and is configured to convert the input signal to packets of data; a clock data recovery circuit coupled to the optical input system which is configured to receive packets of data from the optical input system and is configured to recover clock and data signals having a first frequency from the packets of data; a demultiplexer coupled to the clock data recovery circuit which is configured to deserialize clock and data signals received from the clock data recovery circuit into a plurality of parallel signals having a second frequency lower than the first frequency; an application specific integrated circuit coupled to the demultiplexer which is configured to perform at least one of monitoring and error correction functions at the second frequency on the plurality of parallel signals received from the demultiplexer; a multiplexer and clock multiplication unit coupled to the application specific integrated circuit which is configured to convert the plurality of parallel signals received from the application specific integrated circuit into a signal bit stream at the first frequency, wherein the multiplexer is configured to operate to establish a phase relationship between each of the plurality of parallel signals received from the application specific integrated circuit and convert the parallel signals to a serial bit stream at the first frequency based upon the established phase relationship; and an optical output system coupled to the multiplexer and clock multiplication unit which is configured to retransmit the single bit stream received from the multiplexer and clock multiplication unit onto an output fiber optic channel.
