Orthogonal frequency division multiplexing (OFDM) can accomplish high use effectiveness. In this paper, the authors consolidate OFDM with wavelength division multiplexing (WDM) to examine the optical fiber transmission characteristics of a WDM-OFDM hybrid system that can accomplish high usage effectiveness even when the quantity of channels is high. The outline and simulative examination of the Integrated WDM-COOFDM framework is done at different estimations of the channel spacing. Hence all the info channels have been put directly at different values like 50GHz, 100 GHz and 150 GHz. The most extreme transmission separation accomplished is 600km. Simulation results reveal that with the increase in the channel spacing, the interference decreases and thus the performance is improved. The enhanced Q element and BER acquired with the 150 GHz channel dispersing is 33.4db and 9E-12.
