ABSTRACT:
A connector construction of small sectional dimensions comprises a plurality of cylindrical guides preferably formed of glass and having cylindrical surfaces in side-by-side arrangement. The guides define channels having cusp-shaped interstices, adapted to receive optical fibers to be joined in optical-signal transmissive connections. The channel sectional areas are larger than that of fibers to be received therein. The cusps of such channels defined by converging cylindrical guide surfaces function as fiber-aligning tracks whereby fiber ends aligned on a common cusp track may be butted in a desired end-to-end relation.
The glass guide assemblage is subjected to conditions adequate to allow plastic deformation or the formation of bends in opposed guide portions disposed to either side of a straight, central guide portion. The deformation is adequate to force optical fibers inserted in opposed ends of the assemblage to move into predetermined cusp tracks. After desired bend formation, the assemblage is transversely cut in the central portion and the cut guide faces processed, if necessary, to define smooth, mating faces. Optical fibers inserted in the channels of each half which terminate with the connector finished faces may then be aligned and mated in an opening in a wall or the like for purposes of interconnecting optical fibers disposed to either side of such wall.
