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: An assembly having a protective part including a cap or a plug, a fiber optic component adapted to mate with the protective part and a lanyard. The lanyard has a first end attached to the protective part and a second end attached to the fiber optic component. One of the first and second ends of the lanyard includes a loop defined by a loop member. The loop has a plurality of undulations. The undulations are moveable between a first state and a second state. The undulations are at least partially straightened in a circumferential orientation as the undulations move from the first state to the second state. An inner cross-dimension of the loop is larger when the undulations are in the second state as compared to the first state, and wherein a resiliency of the loop biases the undulations toward the first state.

Abstract: A fiber optic and electrical connection system includes a fiber optic cable, a ruggedized fiber optic connector, a ruggedized fiber optic adapter, and a fiber optic enclosure. The cable includes one or more electrically conducting strength members. The connector, the adapter, and the enclosure each have one or more electrical conductors. The cable is terminated by the connector with the conductors of the connector in electrical communication with the strength members. The conductors of the connector electrically contact the conductors of the adapter when the connector and the adapter are mechanically connected. And, the conductors of the adapter electrically contact the conductors of the enclosure when the adapter is mounted on the enclosure.

Abstract: Certain splice arrangements include first and second laminate structures bonded around a splice location at which two or more optical fibers are spliced (e.g., fusion spliced) together. The first and second laminate structures each include a flexible polymeric sheet and a heat activated adhesive layer carried by the flexible polymeric sheet. Other splice arrangements include a protective barrier disposed about an optical splice. The protective barrier includes first and second protective layers bonded around the optical splice. Each protective layer include a film carrying an adhesive. The protective barrier may be sufficiently flexible to not restrict flexing the optical fibers at the splice location. Example splice arrangements have thicknesses of less than or equal to 1000 microns, or 900 microns, or 800 microns, or 700 microns, or 600 microns or 500 microns.

Abstract: A loop back connector and methods for testing lines in a fiber optic network are disclosed. The loop back connector includes a ferrule having an interface side constructed for optical connection to a multifiber optical cable. The loop back connector also includes first and second optical loop back paths, each having first and second terminal ends positioned at the interface side. The terminal ends of each loop back path are adapted to be aligned to fibers in the multifiber optical cable. The method includes injecting a signal on a first optical path at a first location, looping back the signal at a second location onto a second optical path, and receiving the signal on the second optical path at the first location.

Abstract: A windowless multi-fiber ferrule including a ferrule body. The ferrule body includes a plurality of outer slots. The ferrule body defines an inner passage that extends through a length of the ferrule body from a front end to a rear end. The inner passage includes a main chamber and a row of parallel fiber bores. The ferrule body includes a first and a second major side which each define a plurality of slots. The ferrule body includes ferrule walls which are located between the main chamber and the major sides. The ferrule walls have a first thickness at the outer slots and a second thickness at the regions between the outer slots which is thicker than the first thickness. The main chamber includes sink locations adjacent the regions between the outer slots.

Abstract: A fiber optic cable assembly includes a fiber optic cable and a fiber optic connector. The cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis. Strength components of the cable are anchored to the connector. The fiber optic connector includes a multi-fiber ferrule defining a major axis that is generally perpendicular to the major axis of the jacket and a minor axis that is generally perpendicular to the minor axis of the jacket. Certain types of connectors include a connector body defining a side opening that extends along a length of the connector body; a multi-fiber ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the multi-fiber ferrule has been inserted into the connector body through the side opening.
