Abstract

In the fiber optic communication network for example,- FTTH, EPON, NBN, OTN and so on, the most important components are fiber length between transmitter and receiver point. So, to make, cheap and meaningful communication through optical fiber it must be required to calculate how and what amount of signal is transmitted with the given length of the fiber. Finally, it is said that the optical fiber network have several limitations like extension ratio. So, it is necessary to investigate its affect on the performance of the Optical Network. This research is based on simulation by OptiSystem 0.17 on the basis of Dense wavelength division multiplex (DWDM) technology, Erbium Doped Fiber Amplifier (EDFA), dispersion Compensating Fiber (DCF) and single mode fiber of length 50–100 km.

Highlights

On the basis of parameters like bit rate (B) and spacing between repeaters of the optical fiber networks (L), fiber optic communication is divided into the five generations (Vidmar, 2001; Agrawal, 1997; Addanki, Amiri, & Yupapin, 2018; Mizkuš, 2010; Bansal, Singh, & Gupta, 2008)
The spectral and power efficiency are limited in fiber optic communication system using direct detection scheme
The 20 years continuous effort of scientist, in the optical fiber communication, it is observed that BL product increased generation to generation and in the decades of 2000s we entered in the fourth generation communication system with the bit rate160Gbs and repeater’s spacing 35,000 km and operating wavelength range 1.53–1.5 μm (Liu, 2019)

Summary

Introduction

(3) Polarization mode dispersion—It is really most dominant linear effect for limiting the channel capacity by pulse broadening of the output signal of the system It can be reduced by deterministic differential group delay method and birefringence of the fiber. Treatment of Nonlinearity (XPM) by the adjustment of Power Level in Optical Fiber Communication with Dense wavelength division multiplex (DWDM) system (Nain, Jadon, & Mishra; Ivaniga & Ivaniga, 2019; Ivaniga & Ivaniga, 2019; Kovac, Lukacs, & Gladisova; Ivaniga, Ivaniga, Turan, & Ovsenik, 2017; Archana & Krithika, 2015; Ruzbarsky, Turan, & Ovsenik; Bachrata & Bachraty, 2012) to attain the data transmission rate that increases approximately 1.5 times per year.
