Abstract

Delay ripples of chirped‐fiber Bragg grating (CFBG), which can compensate 200‐km‐long fiber's dispersion, is detailedly analyzed. A numerical simulation of the delay ripple of cascaded gratings is done using Schrödinger's equation and is compared with an experiment using a 1000‐km transmission system over G.652 fiber by five groups of CFBGs for dispersion compensation. The research shows that the system degradation depends on the delay‐ripple period, which is 0.01–0.1 nm, and its amplitude. Fluctuation of the power penalty, which depends on the CFBG's ripple period when the source wavelength is changed ±20 GHz around the CFBG's center wavelength, is experimentally studied. The theoretical results agree well with the experimental results. © 2004 Wiley Periodicals, Inc.
