<abstract>This paper investigates the best modulation format among Non Return-to Zero (NRZ), Carrier-Suppressed Return-to-Zero (CSRZ) and Duo Binary (DB) modulation format for long haul transmission system and to find out the best dispersion compensation technique among the pre compensation, post compensation and symmetrical compensation scheme for the 16 channel DWDM (Dense Wavelength Division Multiplexing) system. The channel spacing between the channel is 200 Ghz and all the channel operates at 40 Gbps data rate. The best transmission modulation format is found by varying the signal input power and analyzing the eye diagram from the BER analyzer of the optiSystem software. It is found that DB modulation format with symmetrical compensation technique is the best method for the long haul data transmission. Analysis is done using Optiwave OptiSystem software. The objective of this paper is to compare three different modulation techniques for different modulation formats for long distance communication.</abstract>
