This paper introduces the non linear optical effect known as four wave mixing (FWM). In wavelength division multiplexing (WDM) systems four wave mixing can strongly affect the transmission performance on an optical link. As a result it is important to investigate the impact of FWM on the design and performance of WDM optical communication systems. The main objective of this paper is to analyze the FWM power for different values of fiber length by designing and simulating a model in Optisim. In this paper, we have simulated the FWM design for three waves. The results obtained show that when the optical transmision length is 100 km, 200 km, 300 km, 400 km and 450 km the FWM power is respectively, becomes about 18 dBm, -8 dBm, -28 dBm, -48 dBm and -58 dBm. This result confirms that the fiber nonlinearities play decisive role in the WDM. It is also to be noticed that as the value of optical length increases, FWM component almost reduces to zero.
