Abstract
Based on analyzing the principle of the Raman Fiber Amplifier (RFA), optimal design of a backward pumping Raman fiber amplifier with five different pump wavelengths was carried out. With seven pump lasers at five different wavelengths and a 100.8 km dispersion-shift fiber, a broadband optical Raman fiber amplifier with gain band over 90 nm, on-off gain of 15.55 dB, gain flatness below 0.87 dB and average effective noise coefficient of -3.5 dB was demonstrated experimentally. The experimental results agree with the theoretical calculation.
