ABSTRACT:
Fiber optic coupler for coupling two mutually isolated optical fibers to a third union fiber rapidly and easily. Two mechanical elements are used, the first one being a hollow cylinder with an inside diameter equal to twice the fiber outside diameter, and the second being a second hollow cylinder with an inside diameter equal to one fiber diameter and an outside diameter equal to twice the fiber diameter. The union fiber is inserted into the smaller cylinder, the two mutually isolated fibers are inserted into the larger cylinder, the empty space in the larger cylinder is filled with an index-matching cement, and the two cylinders are then pushed together. This provides a simple and economical assembly of a coupler which will work for plastic fibers, and does not require any expensive manufacturing steps. Preferably stainless steel is used for the two cylinders.
