Abstract:

Optical signals are transmitted via fiber optic cables. The cable ends have connectors that connect to fiber-optic adapters. The interface between a connector and its adapter typically creates unwanted signal reflections. These unwanted signal reflections are mitigated by including an eight degree angle-offset of one face of an optical fiber within the adapter itself, the other face of the optical fiber having no angle offset, and the adapter being contained within a rigid housing. The angle offset of the fiber optic face in the adapter is mated with a complementary angle offset of the optical fiber in the cable connector. Embodiments of the present invention avoid cable management issues presented by previous adapters that included flexible cable between its input and output the previous adapters being designed primarily as jumpers and not suitable for use in tight, crowded spaces.
