Paper Abstract

We propose and numerically demonstrate impairment compensation via digital backward propagation (DBP) for fiber transmission with distributed Raman amplification. In contrast to EDFA-based systems, signal power evolution in the distributed amplified system has to be obtained prior to DBP by solving the differential equations for Raman amplification. The optimum launching power of an unrepeatered Raman link is significantly increased by nonlinearity compensation.
