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.

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.

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 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: 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: 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 multi-fiber optical connector system including a first and a second multi-fiber connector configured to mate with one another. The multi-fiber connectors include a connector body having a front end and a rear end, a multi-fiber ferrule having a face accessible at the front end of the connector body and a spring for biasing the multi-fiber ferrule in a forward direction relative to the connector body. The spring is configured so that the first and second ferrule rotate with one another or do not rotate when the ferrule is biased forward.
