ABSTRACT:
Disclosed is an improved WDM optical fiber communication system that comprises, in addition to dispersion compensating fiber, dispersion slope compensating fiber (DSCF) selected to provide substantially all channels of the WDM system with nominally zero total chromatic dispersion. Exemplary refractive index profiles for DSCF are disclosed. Such fibers exemplarily can be produced by MCVD.
