OPTIMIZATION OF OPTICAL AMPLIFIER SATURATION POWER IN NGPON2 USING 2048 WAY SPLITTER

Abstract

This article represents design of Next Generation stage-2 Passive Optical Network (NG-PON) for a reach of 100km and over
2048 split using a hybrid time and wavelength division multiplexing (TWDM) for the data rate of 40Gbps. The down stream
signal uses L band and upstream signal uses C band with the wavelength plan of ITU-T G.989. The network provides cost
effective solution by directly connecting the increasing numbers of customers to the core network by use of 2048 way split. The
splitter loss and the ASE noise is optimized by EDFA amplifiers to extend the long reach. An in-depth analysis is performed
using an analytical model of NGPON with non- dispersion shifter fiber.
