ABSTRACT: Dense wavelength division multiplexing (DWDM) is a fibre optic technology that can transmit multiple information streams simultaneously over a single fibre. This paper focusing on to implementation of comparative analysis of dispersion compensated configuration for 40 Gbps dense wavelength division multiplexing (DWDM) system with modulation format (NRZ) and compensation schemes (Pre, Post and symmetrical compensation) at same bit rate 40 Gbps with standard and dispersion compensated fibre on the basis of Q-factor, eye –diagram and bit error rate for fixed gain EDFA and length both type of fibre. On the basic comparison of that Symmetrical compensation is superior to pre and post compensation schemes and gives better results even at high bit rate 40Gbps its transmission distance is 480 km with BER 10-28 and Q factor 10.92 with NRZ format.
