Abstract: Apparatus for casting plugs onto optical fiber ends comprising a mold having a vee-shaped groove for receiving an optical fiber (10) end in butted relationship with either another fiber end or with a mold wall surface (28) which is perpendicular to the vee-shaped groove. Field forces are generated which urge unattached and disposable fiber seating elements (60) into the groove, the seating elements in turn pushing the optical fiber end(s) into the groove until the side surface of the optical fiber end(s) are in tangential contact with both sides (22, 24) of the vee-shaped groove. While the optical fiber end(s) are so positioned, casting liquid is introduced into the vee-shaped groove. The seating elements remain within the casting.

Abstract: Method for connecting optical fibers comprising the steps of molding a first plug onto a first fiber end and a second plug onto a second fiber end, said plugs having three mutually intersecting flat surfaces, one of which is perpendicular to the other two, while a fiber end is positioned against the corner in an orientation such that the end of the fiber butts against said one corner surface and the side surface of the fiber tangentially touches said other two corner surfaces and aligning two such plugs (44, 46), each carrying a fiber end, with each other in an alignment frame (76) having two flat alignment surfaces (22, 24) which are oriented with respect to each other at the same orientation as the two corner surfaces which tangentially touch the fiber side surface. Since these orientations are th the same, the plugs fit precisely into the groove formed by the two flat alignment surfaces of the frame and can be moved toward each other until they touch. In this position the fiber ends carried by the castings are butt aligned.
