Abstract: The nonlinear interference noise in a coherent singlespan fibre-optic communication link (FOCL) with co-propagating Raman amplification is investigated at different levels of input Raman pump and channel powers and dispersion. A simple phenomenological expression for calculating the nonlinear noise power at the output of a single-channel FOCL is presented. The merit of using a distributed Raman amplifier with co-propagating pump up to 1 W in a single-span single-channel FOCL is experimentally investigated.

Keywords: distributed Raman amplifier, co-propagating Raman pump, high-speed coherent communication link, 100 Gbit s^-1, chromatic dispersion, nonlinear interference noise, nonlinear noise accumulation, optical signal-to-noise ratio.
