Abstract
A pair of chromatic dispersion slope compensators (CDSCs) used in tandem to create a 'net CDSC' having a zero-dispersion crosspoint. The paired CDSCs preferably have similar compensating dispersion slopes but opposing average compensating dispersions. The first CDSC may vary in dispersion from a large positive value to a small positive value across the operational bandwidths, while the second CDSC may vary in dispersion from a small negative value to a large negative value across the operational bandwidths. The paired CDSCs may be applied in either order to reduce the dispersion slope of chromatically dispersed light received over a transmission fiber. The CDSCs may be Gires-Tournois etalon (GTE) based.
