ABSTRACT:
Accordingly, an aspect of the present invention provides a method of dynamically controlling a bias point of a photodiode of an optical receiver. According to the present invention a performance parameter indicative of an eye opening of an optical signal received by the optical receiver is detected. A bias voltage of the photodiode s dynamically adjusted so as to optimize a value of the detected performance parameter.
