300mW Pump Laser RFA 2nd Order Distributed Fiber Raman Amplifier
The second-order fiber Raman amplifier is an extension of the first-order fiber Raman amplifier. It adds a pump laser in the 13xx nm band to provide Raman gain for the first-order Raman 14xx nm laser. This effectively reduces system noise and is suitable for more optical signal amplification for long-distance unrepeatered optical transmission systems. The second-order fiber Raman amplifier needs to be used together with the first-order fiber Raman amplifier.
