Abstract

Raman amplification is a popular method used to achieve seamless broadband gain. We evaluate the performance of discrete Raman amplifiers (DRAs) in high capacity C+L band transmission with advanced modulation formats and discuss the challenges associated with expanding the bandwidth to S+C+L band and beyond. Possible architectures, pump-signal overlap issues, and machine-learning based gain flattening techniques are considered.
