RFA5000
C-Band Separate Raman Fiber Amplifier
Product description
1. Raman Fiber Amplifier (RFA) is the only device that can operate in 1300~1600 nm.
2. The gain medium of EDFA is Erbium-doped Fiber (EDF). Its gain area is distributed at long transmitting fiber that is 25km from the output end.
3. Low noise figure marks the super advantages as following:
During Single Mode Fiber(G. 652) transmission, adopting Distributed Raman Amplifier, it can reduce the loss for 5.5dB (Typical value) at effective cross-distance. Compared with EDFA, the input power to the fiber is reduced and the damage of fiber non-linearity effect (SBS) is weakened.
In OSNR calculation, the Equivalent Noise Figure of distributed backward pump Raman Amplifier is 0dB, typical value 0~-2dB, which has remarkable help for improvement of cross-band length, increase system OSNR and transmission distance.
4. With different Raman Gain and Gain bandwidth to meet differential needs. The unit adopts Japanese Fitel Raman pump laser, built-in perfect laser APC, AGC, ATC closed-looped circuit ensuring long life and stable operation of the pump laser.
