Abstract
Described is a method and apparatus for generating a mid-level reference signal and for cancelling amplifier offset in an optical communication system without DC-balancing of optical data. The apparatus comprises an optical-to-electrical converter to receive an optical signal and to generate an electrical signal; an amplifier to receive the electrical signal and to generate an output signal based on a reference signal; a feedback mechanism to be enabled during a training phase only and to generate a control signal from the output signal; and a counter logic having a digital-to-analog converter to generate the reference signal based on the control signal.
