Distributed Fiber Raman Amplifier Pump 500mW Raman Fiber Laser Desktop Type FRA-1450-500-B
The second-order fiber Raman amplifier is based on the first-order fiber Raman amplifier and adds a pump laser in the 1340~1360nm band to provide Raman gain for the first-order Raman 14xx nm laser, which can effectively reduce system noise and is suitable for Optical signal amplification for longer distance relayless optical transmission systems. The second-order fiber Raman amplifier must be used together with the first-order fiber Raman amplifier.
