| Abstract: | In order to realize the flat inline amplification of all dense wavelength-division multiplexing(DWDM) transmission channels in optical communication systems,it is proposed to get a broadband and flat gain for a novel hybrid fiber amplifier based on erbium-doped fiber amplifier and distributed Raman fiber amplifier.Simulation results show that flat gain about 22 dB and low noise characteristics covering the C+L optical communication windows from 1 530 nm to 1 630 nm is obtained by means of this simple design.This design is very important for realizing DWDM system. |
