Method and apparatus for data recovery in an optical transmission system

An apparatus comprising:

• a plurality of parallel detection subcircuits for determining output values of a plurality of sequentially provided electrical representations of optical data bits, the plurality of parallel detection subcircuits comprising a first parallel detection subcircuit and a second parallel detection subcircuit wherein the first and second parallel subcircuits each further comprise a first signal analyzer and a second signal analyzer and said first and said second parallel subcircuits each further comprise a first memory unit and a second memory unit connected respectively to said first signal analyzer and said second signal analyzer, and a selective multiplexer receiving signals from each of said first memory unit and said second memory unit wherein the multiplexer provides output to a third memory unit and an trigger of the multiplexer of the corresponding parallel subcircuit adjacent thereto;
• each of said sequentially provided electrical representations of optical data bits being processed by only one of said plurality of parallel detection subcircuits.
