Performance analysis of optical network based on OADM by using different filters

This paper present an investigation into the effect on the performance of an optical network based on OADM by changing different filters at the receiver side. The calculated average BER and with the help of eye diagrams analyze the response of the filter Bessel, Butterworth and Chebyshev filter and compare the results of the three filters responses in OADM based environment. With the help of OADM network resources are efficiently used, provide protection to network and routing features for add and drop channel. For analyzing of a OADM based network four nodes have been designed transmitting at 10 Gbps data rate connected with four fiber span of 10 Km long of type non linear single mode fiber with average power per channel is -9 dBm.
