Analysis of high‐power EDFA operating in saturated regime at λ=1530 nm and its performance evaluation in DWDM systems

Abstract

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.
