Description

technical field [0001] The invention relates to the field of artificial intelligence, and in particular, to a method and system for improving the performance of a Raman fiber amplifier. Background technique [0002] With the progress of human society, computer networks and data transmission services have developed rapidly, and people have higher and higher requirements for the transmission capacity and transmission distance of optical fiber communication systems. With the maturity of high-power pump laser technology, Raman fiber amplifiers have attracted widespread attention due to their flexible control of gain bandwidth and gain band, and have been widely used in ultra-long-distance and large-capacity transmission systems. Raman fiber amplifier is an important part of dense wavelength division multiplexing (DWDM) communication system. It can directly amplify the optical signal by using the nonlinear effect of stimulated Raman scattering (SRS) in silica fiber. The energy o...
