TOTAL-INTERNAL-REFLECTION FIBER OPTIC INTERFACE MODULES WITH DIFFERENT OPTICAL PATHS AND ASSEMBLIES USING SAME

摘要

Fiber optic interface modules and assemblies using same are disclosed, wherein the module includes first and second lenses formed therein that utilize total-internal reflection within the module body. The first and second lenses define first and second optical paths of different lengths. The module may operably support first and second optical fibers so that they are optically coupled to surfaces of the first and second lenses. The first and second lenses are designed to provide predetermined tolerances for lateral offsets relative to first and second active photo-devices while maintaining respective first and second coupling efficiencies between the active photo-devices and the corresponding first and second optical fibers.
