Abstract
An optical waveguide system exhibiting reduced noise includes a varying dispersion optical waveguide fiber and a high frequency electrical filter. The varying dispersion fiber shifts the frequency spectrum of the noise relative to that of the signal so that the noise can be filtered with substantially no effect on the signal. The varying dispersion fiber is a passive component of the optical system and is compatible with optical connecting and splicing.
