A Fiber Raman Amplifier(FRA) working in C+L band is designed and implemented and the design of the pump driver circuit and the performances of 150 km EDFA+FRA hybrid transmission discussed.The experimental results indicate that the driver circuit operation is stable and reliable and the BER will not be markedly improved when the Raman amplifier gain is lower than 5 dB.The experiment provides a guide to the gain configuration in EDFA+FRA hybrid transmission systems.
