Abstract: A fiber optic ferrule sub-assembly for insertion into an outer housing of a fiber optic connector includes a ferrule assembly having a ferrule that forms an optical communication connection with another fiber optic device. A back housing includes a back post to be attached to a fiber optic cable. A spring is operatively disposed between the ferrule assembly and the back housing. A linkage connects the ferrule assembly to the back housing such that the spring is compressed and biases the ferrule away from the back housing prior to insertion of the fiber optic ferrule sub-assembly into the outer housing.

Abstract: Embodiments disclosed herein are directed to a fiber optic connector with that can be released from a receptacle port such as an adapter or a transceiver. The release assembly is a push/pull tab, a cable boot release and a latch controller called the release types. The fiber optic connector is field installable, and is configured to change polarity when configured with the release types.

Abstract: Splicing or connecting optical fibers extending from a first ferrule and a second ferrule is accomplished using heat or epoxy. Two half ferrules of differing dimensions or the same dimensions are secured together using a pair of guide pins. One of the two ferrules is biased by a spring forward and against a second ferrule to form the mechanical transfer ferrule. The mechanical transfer ferrule is secured within an inner housing of a fiber optic connector by a spring push that is secure to a distal end of the inner housing. A slidable outer housing biased forward by an elastic arm that ensures the fiber optic connector with the spliced two half ferrules is secured within an adapter port.

Abstract: A fiber optical connector assembly with a crimp tube assembly improves tensile load on the optical fiber cable or microduct jacket when the connector assembly is used as part of an optical network that is secured between towers spaced apart 1,000 meters or more. The crimp tube assembly has one or more crimp zones, and the crimp tube assembly has a lip formed on an inner surface of the crimp right assembly to improve tensile strength when the crimp tube assembly is secured to a back post of a first fiber optic connector assembly that is air blown or push through a duct or conduit. An epoxy resin may be injected into a cavity between the cable jacket and the crimp tube assembly to improve tensile load strength.

Abstract: A fiber optic connector having a ferrule that forms an optical connection with another fiber optic connector. An outer housing supports the ferrule and has a front end portion and a longitudinal centerline axis. The front end portion includes a front end face with a portion of the ferrule being forward of the front end face. The front end portion includes a protector that is shaped and arranged to protect the ferrule. The protector is arranged so that the fiber optic connector and another fiber optic connector of identical construction can, starting in the same orientation, be mated together by rotating said other fiber optic connector 180° about an axis perpendicular to the longitudinal centerline axis, aligning the longitudinal centerline axes and moving the fiber optic connectors along the longitudinal centerline axes until the fiber optic connectors are mated to form the optical connection.

Abstract: A spring body configured with a plural of spring segments formed along a longitudinal axis of the spring body. The spring segments form an opening along one side that is configured to accept one or more optical fibers, and secure the fiber bundle from being dislodged from a bore formed by the spring segments.
