Abstract

In long distance communications systems at bit rates of 10 Gb/s and higher, dispersion compensation is required to maintain adequate system performance. Dispersion compensation is generally passive in 10 Gb/s systems and both passive and dynamic in 40 Gb/s and higher system demonstrations. For passive applications involving a limited number of channels, chirped fiber Bragg gratings (FBGs) have been shown to have acceptable performance characteristics.^1–4 Both linearly and nonlinearly chirped FBGs are used for dynamic dispersion compensation.^5–8
