Effects of cross-phase modulation crosstalk in WDM networks on received power and number of channels for various fiber types

We present a comprehensive theoretical study of cross-phase modulation in optical fiber with exploring four fiber types. The cross-phase modulation induced crosstalk noise is described by a system of coupled equations, which describes mutual channel interference optical losses in multi channel optical communications system. The corresponding system of equations has then been numerically integrated, and the channels interaction phenomena such as cross-phase modulation have been described. System performance is evaluated through determining the cumulative crossphase modulation crosstalk relation with both of the received power and number of channels. Various types of optical fiber have been used in the numerical results. The results can be generalized for all other types of optical fiber.
