Applications of erbium-doped fibre amplifiers in communications
Applications of erbium-doped fibre amplifiers in communications
Erbium-doped single-mode fibre amplifiers (EDFA) which operate around lambda = 1.54µm, coinciding with the low-loss region of silica optical fibre, show great promise for use in future high-performance telecommunication systems. This is due to a combination of high saturation power, low noise, immunity to crosstalk, low power requirement and the ability to work at high data rates. In addition, compatibility with existing fibre components is excellent, allowing all-optical fibre circuitry to be assembled with both active and passive components. This is particularly beneficial for the fibre amplifier, where splicing of the active fibre into the telecommunications link virtually eliminates, troublesome Fresnel-reflection feedback which normally limits the gain in semiconductor laser amplifiers. As such the application of EDFAs to high data rate long-haul communications, multichannel distribution networks and analog video distribution have been successfully demonstrated. This paper will discuss the characteristics of EDFAs, highlight their advantages and review current applications.

Abstract
Erbium-doped single-mode fibre amplifiers (EDFA) which operate around lambda = 1.54µm, coinciding with the low-loss region of silica optical fibre, show great promise for use in future high-performance telecommunication systems. This is due to a combination of high saturation power, low noise, immunity to crosstalk, low power requirement and the ability to work at high data rates. In addition, compatibility with existing fibre components is excellent, allowing all-optical fibre circuitry to be assembled with both active and passive components. This is particularly beneficial for the fibre amplifier, where splicing of the active fibre into the telecommunications link virtually eliminates, troublesome Fresnel-reflection feedback which normally limits the gain in semiconductor laser amplifiers. As such the application of EDFAs to high data rate long-haul communications, multichannel distribution networks and analog video distribution have been successfully demonstrated. This paper will discuss the characteristics of EDFAs, highlight their advantages and review current applications.
