Simplex connectors for multicore optical fiber cables

摘要

An optical fiber cable connector includes a ferrule subassembly, in which a ferrule is mounted into a receptacle including a barrel section having a flange at its base. The ferrule subassembly is loaded into an enclosure having a plug housing at its lead end. The plug housing is configured to provide a connection between an endface of a multicore fiber mounted into the ferrule and a corresponding surface in a mating socket. A collar is rotatably mounted onto the barrel section of the ferrule subassembly such that it butts up against the flange. The collar has an opening that fits around the barrel section, and an outer perimeter that fits into a receiving cavity with the plug housing. The ferrule, receptacle, receptacle barrel section, mounted multicore fiber, enclosure, and plug housing have a common longitudinal axis. As a result, the ferrule, receptacle, receptacle barrel section, and mounted multicore fiber are continuously rotatable with respect to the enclosure and plug housing, thereby enabling a precise rotational alignment of the multicore fiber within the enclosure.

主权项

1. An optical fiber cable connector, comprising:
a ferrule subassembly, including
a ferrule,a receptacle having a lead end to which the ferrule is mounted, anda flange extension member mounted to the tail end of the receptacle; an extender having an internal opening closely fitting around the flange extension member; and an enclosure in which the ferrule subassembly is loaded, wherein the ferrule subassembly, extender, and enclosure have a common longitudinal axis, wherein the ferrule subassembly and extender are continuously rotatable within the enclosure, wherein the rotation of the ferrule subassembly and extender within the enclosure is controlled by rotation of an exposed rear end of the extender, and wherein the flange extension member and the extender internal opening have a polygonal perimeter.
