Flat Gainon C-band using Raman-EDFA Hybrid Optical Amplifier for DWDM System

Abstract

An efficient optical link which provides flat gain over C-band has been designed using a
raman fibre amplifier and an Erbium doped fibre amplifier (EDFA) in a hybrid configuration
for dense wave division multiplexing system (DWDM). With an input power of 3 mW, gain of
> 40 dB is obtained across the range of 1530 nm to 1565 nm with a gain variation of <1.2
dB without using any gain flattening techniques.
