Abstract: A fiber optic connector and cable assembly includes a cable with one or more strength members secured to a connector that is connectable to both a hardened and a non-hardened fiber optic adapter. The cable can include multiple cable types with various shapes and strength member configurations. The connector includes a connector housing having a one-piece main body and a cover piece mounted thereon. The one-piece main body defines a plug portion compatible with the adapters. A ferrule assembly is mounted in the plug portion and biased outwardly by a spring. An insert within the connector housing includes a spring stop for holding the spring and a cable retention portion for securing the strength members of the cable. The spring stop and the cable retention portion can be included on a one-piece insert or they can separately be included on separate inserts. The cable retention portion of the insert and the cover piece can take various forms suited for a particular cable of a given fiber optic connector and cable assembly.

Abstract: Aspects and techniques of the present disclosure relate to a fiber optic connector assembly including a fiber optic connector with a front end and a back end. A ferrule positioned at the front end. The ferrule has a distal end face with a central region and recessed regions on opposite sides of the central region. The assembly includes a dust cap mounted on the ferrule. The dust cap has an open end and an opposite closed end. The fiber optic connector assembly also includes a tape member that covers the central region of the ferrule. The tape member can be secured to the dust cap such that when the dust cap is removed, the tape member simultaneously comes off with the dust cap.

Abstract: A multi-fiber cable assembly includes an optical connector and a cable. The optical connector includes a connector body; an optical ferrule body, and alignment elements. The optical ferrule body has an end face defining a plurality of alignment openings arranged in rows and has a plurality of buckling chambers. Each buckling chamber is aligned with one of the rows of the alignment openings. The optical fibers of the cable have bare portions secured at a first end of the optical ferrule body using rigid epoxy. Each of the optical fibers is routed through one of the buckling chambers to one of the alignment holes.

Abstract: Optical connector arrangements terminate at least seventy-two optical fibers. The optical connector arrangements include multiple optical ferrules that each terminates multiple optical fibers. Some example optical connectors can terminate about 144 optical fibers. Each optical connector includes a fiber take-up arrangement and a flange extending outwardly from a connector housing arrangement. The fiber take-up arrangement manages excess length of the optical fibers. A threadable coupling nut can be disposed on the connector housing arrangement to engage the outwardly extending flange. Certain types of optical connector arrangements include furcation cables spacing the connector housing arrangement form the fiber take-up arrangement.
