Abstract :
The use of a fibre Raman amplifier as a repeater amplifier and a power amplifier is studied by considering the third Stokes generation. Due to the multiple Stokes generation, there exists a limit on the achievable amplifier gain. With optimum pump powers, maximum amplifier gains of up to 58 dB and 28 dB are achievable for a repeater amplifier and a power amplifier, respectively.
