| Abstract | ||
| Wavelength division multiplexing (WDM) is a technology that enables the transmission of several optical signals simultaneously at different carrier wavelengths on a single fiber and the separation of the signals by wavelength at the receiving node. While WDM is very attractive, it has some disadvantages also. One such disadvantage is the appearance of fiber nonlinearities. With the use of multiple channels, several miliwatts are injected into the fiber. Such high powers lead to the appearance of different nonlinear effects in the fiber, mainly the Stimulated Raman scattering (SRS), Stimulated Brillouin scattering (SBS), Four wave mixing (FWM), and the Cross Phase Modulation (CPM). These nonlinear effects lead to the degradation of system performance. In this work the performance analysis of nonlinearities in the WDM systems was implemented using Mat lab-(7). | ||
