Distributed Raman Amplifier in O, E, S, C & L Band DWDM Network

Optical Fiber communication can smoothly operate in the wavelength region lie within 1260–1650 nm where transmission loss is minimum. In the present article, performance of Distributed Raman Amplifier (DRA), within above band through simulation technique on MATLAB platform has been observed. Present observations have realized by defining new embedded block sets for multichannel amplification. Observed results have been found by studying the variation in output power and its respective gain of DRA with respect to spectral variations in Co-pumping configuration and for the same input power value in all channels. From above observations, it has been realized that flatness in output power of DRA is comparatively better in C & L-band. Observed gain flatness in E-band is comparatively better than O & S band but inferior to C & L. It is well known that optical communication lying within O to L band is always usable for long haul communication with such a high speed data transmission rate of 100 Gbps and from our present observations, it can be justify that communication link set up in C, L and in next E-band is preferable.
