Chromatic Dispersion Compensation Effect Performance Enhancements Using FBG and EDFA-Wavelength Division Multiplexing Optical Transmission System

Abstract

An optical transmission system using Fiber Bragg Grating (FBG) and Erbium Doped Fiber Amplifier (EDFA) with new proposed model has been analyzed to overcome chromatic dispersion and attenuation phenomena. To evaluate the transmission system performance of the received signals, a simple model of one channel transmission has been developed in the first step. Also, optical fiber length and attenuation coefficient parameters have been investigated in detail to deal with the optimized corresponding parameter values. Results show that the performance of the optimized design parameters is very efficient in terms of output power (dBm), noise figure (dB), gain (dB), and -Factor. The model of one channel developed previously has been adapted to a complex model of four optical channels multiplexing with different wavelengths. FBG and EDFA have been also added to WDM technology system to enhance the chromatic dispersion and the signal attenuation. Results show that the new model is more efficient in terms of -Factor and eye diagrams.

Theoretical Analysis of a Novel WDM Optical Long-Haul Network Using the Split-Step Fourier Method

“…Figure 1 shows the optical system designed in this paper. e EDFA is introduced with the aim to encounter the attenuation phenomena, while the FBG is introduced to compensate chromatic dispersion and to decrease nonlinear effects [16]. To determine the gain of the optical network, we have divided the simulation system into three sections, the first one is formed by the multiplexing output with singlemode fiber (SMF), the second is made up by SMF-FBG with FBG-EDFA, and the third section is formed by EDFA with the demultiplexing input.…”

A comparative study of chromatic dispersion compensation in 10 Gbps SMF and 40 Gbps OTDM systems using a cascaded Gaussian linear apodized chirped fibre Bragg grating design

“…The works presented in [ 8 ] uses a combination of EDFA and FBG to reduce dispersion effects on both a single channel and four-channel system. In [ 15 ], chromatic dispersion is compensated using chirped FBG in conjunction with EDFA to reduce attenuation for wave division multiplexed (WDM) optical system using four channels.

Chromatic Dispersion Compensation Using Adaptive Fiber Bragg Grating for High-Speed Optical Communication

“…Dispersion is foremost among all losses. In dispersion [2][3][4][5] overlapping of pulse happens and which lead to an error while receiving the signal. Even one can not predict the output or the original signal which was sent by the transmitter.…”
