Investigations on the performance of distributed Raman amplifier in dense wavelength division multiplexed communication system using different modulation formats
Abstract:Here, the amplification performance of distributed Raman amplifier in a dense wavelength division multiplexed (DWDM) system is analyzed. We aim to compare the performance of distributed Raman amplifier using different digital modulation formats accordant with the bit error rate (BER) and Q factor through simulations. The various pumping methods like forward pumping, backward pumping, and bidirectional pumping for different pump powers have been compared by varying the modulation formats.Binary phase shift Keyi… Show more
