Trunk and distribution network application of erbium-doped fiber amplifier

Abstract

Recent research on erbium-doped fiber amplifiers and their applications to trunk and distribution networks is described. Simple methods to estimate amplification performances from only three basic erbium-doped fiber parameters are proposed. It is clarified that optical amplifiers greatly influence the development of future optical communication systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
