Selective Hybrid EDFA/Raman Amplifier Placement to Avoid Lightpath Degradation in (C+L) Networks

We investigate optimized placement of hybrid EDFA/Raman amplifiers in (C+L) networks to avoid lightpath degradation due to ISRS. We numerically compare eight strategies for amplifier deployment showing that an optimized placement of Raman amplification can lead to 40% fewer amplifiers compared to baseline deployment practices.
