Abstract

See full text

An optical fiber includes a large graded index core of Ge doped silica for an increased bandwidth-length-product of over 100 MHz-km. A cladding layer of non-doped silica is formed on the core during the preform process and subsequently during drawing the preform an ultraviolet light curable polymer first coating is overlaid on the cladding layer. The first coating is sufficiently hardened to match the fracture characteristics of the silica core and cladding layer to facilitate crimp and cleave termination. The first coating is additionally provided with an index of refraction greater than the cladding layer to enable mode or energy stripping from the cladding layer. A second polymer layer may optionally be applied during draw for protection and to provide a tough outer layer of the optical fiber for the deformable features of a connector to hold onto after crimping.
