ABSTRACT:
Multimode optical fibers are described comprising a cylindrical core with a radius a.sub.o exhibiting an index of refraction n.sub.o surrounded by a cladding having an outer radius a in which the index of refraction varies continually from the core to the periphery from a value of n.sub.1 to a lower value n.sub.e. Between the core and cladding there is a step change .DELTA.n in their respective indices of refraction whose value is a function of the ratio a.sub.o /a. Such fibers have both slight attenuation and slight dispersion and can be manufactured using processes similar to those used in making step-index optical fibers.
