Abstract
End of line dispersion compensation is applied on a sub-band by sub-band basis. Adequate end-of-line dispersion compensation may be provided for high data rate WDM systems even for optical link lengths of 1000 km or more. Dispersion compensating gratings (DCGs) may be used as the dispersion compensating components. There is a great savings in cost and package volume compared to per-channel compensation schemes.
