ABSTRACT:
A fiber optic connector apparatus (10) for coupling two fiber optic cables (12, 14) including a pair of connectors (48, 98) permanently attached to the fiber optic cables (12, 14). The connectors include a protruding portion (58, 102) with a central opening therethrough for receiving the fiber optic cables (12, 14). The protruding portions have a flat face (56) on their distal end and the optical fibers (16, 26) are inserted into the protruding portion (58, 102) so that end of the optical fiber (16, 26) lies in the plane of the flat face of the protruding portion (58, 102). A recessed portion (60, 104) in the flat face surrounds the optical fiber end to create an air space around the optical fiber ends. An interconnect member (86) removably adjoins a pair of the connectors (48, 98) so that the optical fiber ends are held in close proximity to each other. The close proximity reduces transmission losses and the recessed portion (60, 104) reduces the possibility of damage to the optical fiber ends should high power light energy escape at the interface and melt the parts of the connector. The connector apparatus (10) also permits the optical fiber ends to be easily inspected and cleaned when disconnected.
