Abstract

In this paper, we have investigated cross phase modulation (XPM) effect by copropagating two channels having wavelength of 1550.1 nm and 1550.4 nm with backward pumped fiber Raman amplifier (FRA). The cross phase modulation (XPM) effect has been analyzed by changing various parameters of FRA. It is proposed that XPM increases with increase in input signal as well as pump signal power. XPM is also analyzed for different values of Raman fiber lengths and bit rates and we have achieved that the optimum value of bit rate for which the XPM is minimum for this channel spacing at 10 Gbps..
