HTFuture Distributed Raman Amplifier pump Module provides optimized pump source for Raman amplification. It includes the Co-pump and counter -pump for the distributed amplification. for counter pump, It can provide 10dB (typical value) flat gain for high speed, large capacity and long-haul transmission systems. 

for co pump, it can provide about 4~10 dB gain, which depends on the actual Configuration of the system. Pumping power of each wavelength can be Conveniently adjusted to meet possible system change.
