Abstract
Due to the growing demand in Telecommunications and Triple play services must to increase bandwidth and transmission rate. Optical Telecommunication Fiber is an excellence transmission medium through high bandwidth and its low loss. However, with increasing the transmission rate, nonlinear effects is one of the key limiting factors on the transmission of signals over an optical fiber, in particular the nonlinear Kerr effects, especially in the presence of chromatic dispersion and polarization mode dispersion. The importance of nonlinear effects depends on a large of fiber signal and system parameters. Nonlinear effects degrade signal quality as the launched signal power is increased. The article gives a detailed of analysis of intrachannel nonlinear effect such as intrachannel cross-phase modulation and intrachannel four-wave mixing. We used the nonlinear Schrodinger equation to understand the cause of intrachannel nonlinearity. And we proposed the method for the mitigation of these effects in optical transmission systems.
Keywords: nonlinear effect, intrachannel cross-phase modulation, intrachannel four-wave mixing, chromatic dispersion, input power.
