Enhancement in the Gain of EDFA in Fiber Optic Communication

Research Paper (postgraduate) from the year 2019 in the subject Instructor Plans: Computing / Data Processing / IT / Telecommunication, , course: M.Tech, language: English, abstract: Fiber amplifiers are a crucial and fast-growing field in the communication system. The study of this field show that the formulation procedures of lasers generation and amplifier amplification displays a problematical process due to the factors affecting and changing amplifier and laser significance in a dynamic way. Gain, noise figure, wavelength, power flatness and power output are directly affected by any element or parameter inside the amplifier configuration. The design parameters such as: erbium ions concentration, EDF length, isolators, wavelength division multiplexing (WDM) position, pump power position, circulators, pump directions, all of these elements and factors are affecting directly the amplifier output. EDFA is an amplifier that is best used because of its low loss and high gain. For communication, there are two windows 1530-1560nm(C-band) and 1560-1610nm (L-band).
