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

Pravin R. Prajapati, Mr. Akash Saxena, Yohan Dastoor

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.
