Abstract: Disclosed is a negative total dispersion waveguide fiber having low attenuation and sufficiently good resistance to bend loss that attenuation is not impacted by cabling or otherwise buffering the waveguide. The total dispersion slope of the waveguide fiber is positive so that the zero dispersion wavelength is greater than 1600 nm. The waveguide fiber may advantageously be used in a link having a distributed feedback laser as a signal source. The negative dispersion of the waveguide in accordance with the invention compresses the launched signal pulse when the laser is positively chirped. The laser is operated at optimum bias, which results in positive chirp, but no dispersion penalty is incurred in the link. The waveguide fiber in accordance with the invention may also be advantageously used as a dispersion compensating fiber in a high performance multiplexed telecommunications link.
