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

摘要

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.
