Abstract: An optical fiber connector has a housing including an axially extending passage with an exterior opening of first diameter and an interior opening of second diameter less than the first diameter and a frustro-conical wall bounding the passage and extending between the exterior and interior openings. The wall has an axial slot extending therethrough of axial extent equal to or less than the passage and extending axially across the interior opening. A separate biasing member may be included. The housing is thus equipped with selective radial expansibility for facilitating seating therein of an optical fiber plug having a frustro-conical exterior surface and an optical fiber centrally interiorly thereof.

Abstract: An optical fiber assembly adapted for diminished back reflection along the fiber longitudinal axis includes a housing having a passage between end openings for residence of an opticle fiber. The passage is inclined with respect to an output energy axis and the fiber has its end face intersected by the output axis and prepared at an acute angle with respect to its longitudinal axis.
