Distortion of an optical signal transmitted over a fibre optic link is characterized by a receiver including a photodetector for converting optical radiation into an electrical signal. A delay line delays the electrical signal. At least two delay line taps drive a register that stores plural values corresponding with different delayed replicas of the electrical signal. Signals commensurate with the values are externally provided to a signal distortion analyser for analysis of the values to determine the optical signal distortion.

Communications test receiver

A method and apparatus for providing diagnostic features for an optical transceiver, in which the optical transceiver uses electronic dispersion compensation (EDC) in order to alleviate distortion of a signal caused by dispersion. A method and apparatus for monitoring the performance of an electronic dispersion compensator by monitoring one or more signals from the electronic dispersion compensator and generating an alarm in the vent that the performance of the electronic dispersion compensator falls below a certain threshold.
