Experimental Evaluation of HOA in Terms of Flat Gain in C-Band for Super Dense Optical Communication System

Abstract

The impact of RAMAN–EDFA hybrid optical amplifier (HOA) in C-band for 80 × 10 Gbps super dense wavelength division multiplexing (SD-WDM) system with the channel spacing of 12.5 GHz is analyzed. A flat gain of (> 17 dB) is obtained with suitable pump power of HOA in the wavelength range from 1545 nm to 1565 nm with less variation of 5 dB. Further, the performance of the proposed system is also evaluated in term of acceptable flattened gain without using any cost effective technique. The recorded value of crosstalk (< 10−1) and power penalty (− 0.5) dB are also supported to maintain long haul super dense optical communication.
