1425nm~1465nm distributed second-order fiber Raman amplifier
On the basis of the first-order fiber Raman amplifier, the second-order fiber Raman amplifier adds a pump laser in the 1340~1360nm band to provide Raman gain to the 14xx nm laser of the first-order Raman, which can effectively reduce the system noise and is suitable for optical signal amplification in longer-distance relayless optical transmission systems. This second-order fiber Raman amplifier must be used in conjunction with a first-order fiber Raman amplifier.
