OPTICAL FIBER WITH A HIGH REFRACTIVE INDEX EDGE WHICH REFRACTS ERRANT SIGNALS FROM CORE CLADDING An optical communications fiber is made from a core of high refractive index glass, a cladding of lower refractive index glass, and an edge cladding of a high refractive index glass. This optical fiber does not depend upon the refractive index of the polymeric coating to function properly, because the edge cladding refracts the errant light away from the core and cladding. |
