【Abstract】 The history, principle, optimum design,current status and prospect of distributed fiber Raman amplifier(FRA) are discussed. The S band configuration of dispersion compensation distributed fiber Raman amplifier has been researched and developed. The gain spectrum and noise character of the 5 km DCF-50 km G652 fiber configuration dispersion compensation distributed FRA pumped by a fiber laser have been researched in the forward pump and backward pump conditions. The gain flatness filter of FRA has been designed and manufactured by the optical fiber grating and gets a good result. The application test in the campus network was done and got a good result.更多还原
