“…The combined use of DRA and EDFA can significantly increase the total gain of the long distance optical communication system and improve the system Q value, and the transmission distance of the system is the largest. The gain spectrum is wide, and the effective gain of the 40nm range can be realized by single wavelength pump on DSF [3][4][5][6] .…”

Nowadays, the broadband demand increases dramatically, therefore, the optical fiber communication core network have to develop for larger capacity and longer distance. In view of the construction of DWDM(Dense Wavelength Division Multiplexing) transmission system, the combination of FRA(Fiber Raman Amplifier) and EDFA(Erbium Doped Fiber Amplifier) is proposed for the networking of DWDM transmission system, so as to solve the problems of the large capacity and long distance of optical fiber communication core network. By comparing and analyzing the transmission performance between EDFA and FRA, the DSF(Dispersion Shifted Fiber) is adopted, and the DWDM system structure is composed of DRA(Distributed Fiber Raman Amplifier) and EDFA. The application shows that the Raman gain and EDFA gain are flat, and all channel error rates reach 10-9 .
