On the basis of the first-order fiber Raman amplifier, the second-order fiber Raman amplifier incorporates a pump laser in the 1340~1360nm wavelength band to provide Raman gain for the 14xx nm laser of the first-order Raman amplifier. This effectively reduces system noise and is suitable for amplifying optical signals in longer-distance unrepeated optical transmission systems. The second-order fiber Raman amplifier must be used in conjunction with the first-order fiber Raman amplifier.
