ABSTRACT:
An optical coupler is provided for connecting between optical fibers and electro-optical elements in optical communication systems. The coupler comprises one element consisting of a connector fiber within a support tube fixedly attached to the electro-optical elements at one end and optically polished at the other end. Connection between the connector fiber and an optical communication fiber is provided by means of a second element consisting of a dual diameter connector tube. The dual diameter tube slidingly engages the support tube at one end and the systems fiber at an opposite end to provided close optical proximity between the systems fiber and the connector fiber.
