Dispersion cancellation using optical-fiber filters

The anomalous dispersion characteristic of recently reported [Opt. Lett. 5, 476 (1980)] optical-fiber filters is proposed for use in equalization of material dispersion in optical-communication (OC) links employing single-mode fibers. Calculations show that, under appropriate circumstances, a fiber filter of length shorter than 2 cm can equalize dispersion from an OC link about 1 km long.
