It has been numerically demonstrated that machine learning offers significant advantages for predicting Raman amplification gain and noise profiles in terms of speed and computational complexity.
This chapter explains how to configure and verify Raman tuning and interpret status and parameter details. It covers tuning modes, activation conditions, and operating with OTDR lock and
Raman tuning parameters This section describes the parameters used by the Raman tuning algorithm to optimize Raman amplifier performance. The Raman tuning algorithm uses the following parameters
For a short-reach metro network or DCI application with high-data-rate transceivers, the distributed Raman amplifier delivered the best transmission performance, compared with any other amplification
In the lumped case, the Raman amplifier consists of a sufficiently long spool of fiber along with the appropriate pump lasers in a package. In the distributed case, the fiber can simply be the fiber span
The Raman amplifier is a distributed amplifier. It can be used at both the transmit end (for forward amplification) and the receive end (for backward amplification).
Shows the automatic optimization of a 12-pump Raman amplifier to give 0.2 dB ripple over an 80-nm bandwidth (1527 nm-1607 nm). The optimization can be performed for uni- and bi-directional pumping.

Hello, Mohamed. It really was a lack of attention coupled with fatigue. Shortly after commenting I realized that I was not selecting “Raman gain efficiency” and it worked. Thanks for the tip.
In general, Raman amplification based on stimulated Raman scattering (SRS) is modeled by a set of ODEs describing the power evolution along frequency and spatial positions :
Raman amplifiers are optical amplifiers based on Raman gain. They are often operated with light pulses, although continuous-wave operation is also possible.
In practice, a Raman amplifier uses multiple pump lasers to realize high gain and flatness. Using a polarization multiplexer, two pump lasers with the same center frequency can be used to double
The proposed method makes it possible to design multiwave-length pumped Raman amplifiers with the best possible (or very close to that) gain flatness within the specified constraints, such as the number
