DESCRIPTION Graded index fibers have a doped silica core in which the refractive index increases progressively toward the center. This design which reduces modal dispersion allows higher bandwidth as compared to step index fibers with same core diameter. The range conforms to market standards and named according to their core and cladding diameter in µm: 50/125, 62.5/125, 100/140.
APPLICATIONS These fibers are specified mainly for datacom transmission over short or medium distances at 850 nm and/or 1300 nm.Typical applications are local area and wide area networks, carrying data, voice and/or video services. GI 62.5/125 are specified by industry standards for all fiber-optic network protocols including Ethernet, Token Ring, FDDI and ATM.
