Second-order fiber Raman amplifier
The second-order fiber Raman amplifier adds pump lasers in the 1340~1360nm band to a first-order fiber Raman amplifier, providing Raman gain for its 14xxnm laser. This reduces system noise and supports signal amplification in longer-distance unrepeatered optical transmission systems. It must be used together with a first-order fiber Raman amplifier.
