Performance Characteristic of Distributed Erbium Doped Fiber Amplifier(D-EDFA) [PDF]
Engineering and Technology Journal, 2010 D-EDFA have their signal gain distributed over long fiber lengths. This paper deals with gain and noise figure characteristics at 150dB/km Rayleigh constant of a forward, and bidirectional pumped distributed EDFAs, operating in 1550 nm as a function of ...

Hybrid Machine Learning EDFA Model [PDF]
Optical Fiber Communication Conference (OFC) 2020, 2020 A hybrid machine learning (HML) model combining a-priori and a-posteriori knowledge is implemented and tested, which is shown to reduce the prediction error and training complexity, compared to an analytical or neural network learning model.

Gain and Noise Figure Performance of Erbium-Doped Fiber Amplifiers [PDF]
Kirkuk Journal of Science, 2008 Fiber loss is a fundamental limitation in realizing long haul point–to-point fiber optical communication links and optical networks. One of the advanced technologies achieved in recent years is the advent of erbium doped fiber amplifiers (EDFAs) that has

Measuring Optimal Length of the Amplifying Fiber in Different Working Conditions of the Amplifier
Advances in Electrical and Electronic Engineering, 2014 The aim of this article is to highlight possible unwanted behaviour of an EDFA optical amplifier during temperature changes. After a brief introduction dealing with amplifiers and doped fibers in general we focus on the assembly of our own EDFA amplifier

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]
, 2000 We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...

Journal of Information and Telecommunication, 2020 Optical Communication system consists of three main blocks, such as a transmitter, a transmission channel and a receiver. The modulation and demodulation techniques are the most important for the transmitter and receiver, respectively, to transmit and ...
