Optical nonlinearities give rise to many ubiquitous effects in optical fibers. These effects are interesting in them and can be detrimental in optical communication. In the Dense Wavelength division multiplexing system (DWDM) the nonlinear effects plays important role. DWDM system offers component reliability, system availability and system margin. DWDM system carries different channels. Hence power level carried by fiber increases which generates nonlinear effect such as SPM, XPM, SRS, SBS, and Four waves mixing (FWM). FWM is one of the most troubling issues. The FWM gives crosstalk in DWDM system whose channel spacing is narrow. Wavelength exchanging enables data swapping between two different wavelengths simultaneously. These phenomena have been used in many applications in DWDM optical networks such as, wavelength conversion, wavelength sampling, optical 3R, optical interconnects and optical add-drop multiplexing.

Effect of Dispersion and Fiber Length on Four Wave Mixing in WDM Optical Fiber Systems
2015
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 and dispersion 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 fiber length and dispersion value is increased FWM effect reduces. This result confirms that the fiber nonlinearities play decisive role in the
Four-Wave Mixing Effects on BER for different Fibers in WDM Optical Communication systems
Four-Wave Mixing is the major degrading factor in WDM optical communication system along with other non-linearties. This paper simulates the four equally spaced channel WDM optical communication system to investigate the effect of FWM on bit rate for different type of optical fibers. BER for different fiber at various dispersion values has been obtained for optical link having two spans of 100 km each. It has been observed that the performance of Sumitomo fiber is better and gives BER of 10 -12 even if the dispersion is high (14.14 ps/nm/km) in comparison with other fibers reported in this paper.
