Abstract

This paper presents the numerical analysis of an EDFA operating in the saturation regime. Erbium-doped silica fibers with higher numerical aperture and erbium ion concentration can yield high output signal powers. The study of multichannel signal amplification in a high-power EDFA shows that the gain excursion in a particular channel lies within 0.5 dB as long as the number of channels dropped does not exceed a certain limit. © 2002 John Wiley & Sons, Inc.
