The rapid growth of optical networks and huge data traffics being carried by the network has made it critical to monitor the system at different locations between source to destination nodes. The output of the amplifier can be used to control the magnitude of disparaging effects through amplifiers, compensators etc. This paper reviews the different optical performance monitoring techniques proposed in the literature so far based on electrical post processing techniques. These methods implements FIR filters, eye diagrams, delay tap sample plots, constellation diagrams, histograms etc for performing OPM on optical network. The need to build efficient OPM is outlined.
