Fiber optic coupler combiner

摘要

A fiber optic coupler having a first lens element (1) for inputting a point source (16) of light from an optical cable and outputting a collimated light, optically coupled to one or more lens elements (2) for receiving an input of collimated light from the first lens element and outputting a focused point of light into a fiber optic cable. The lens elements (1,2) can be gradient index lens. The lens elements can be of varying sizes such that the first lens element can optically connect to one or more smaller lens elements to couple or split optical signals for two way communication on the optical cables.
