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: The present disclosure relates to a field installable connector system. The connector system includes a factory terminated subassembly including a ferrule terminating an optical fiber of an optical fiber cable. The factory terminated subassembly has a small transverse cross-section to facilitate routing through a duct. The connector system also includes a field installable subassembly including various connector components that can be installed after the factory terminated subassembly has been routed through a duct. The components can be sealed and hardened.

Abstract: A break-out assembly includes an enclosure defining a first port at the first end to receive an optical cable and a second port at the second end to receive a plurality of break-out cables. Each port leads to the interior of the enclosure. A cable retention region defined within the enclosure at the second end is configured to enable the break-out cables to each secure to the enclosure at one of a plurality of axial locations. Certain types of break-out assemblies include other cable retention regions to axially and/or rotationally secure the optical cable to the enclosure. A splice retention region is disposed within the enclosure between the first port and the second cable retention region. The splice retention region receives optical splices at which optical fibers of the optical cable are spliced to optical fibers of the break-out cables.

Abstract: The present disclosure incudes a fiber optic cable having a conduit including a conduit wall defining a conduit passage that extends longitudinally through the conduit. The conduit also includes an adhesive injection port defined through the conduit wall and at least one optical fiber within the conduit passage. The cable further includes a fiber lock including an adhesive volume in communication with the adhesive injection port. The adhesive volume includes a main adhesive volume positioned within the conduit passage and bonded to the optical fiber. The main adhesive volume is fixed to prevent longitudinal movement relative to the conduit.

Abstract: A method for processing ferrules for fiber optic connectors is disclosed herein. The method involves ablating a distal end face of the ferrule with the plurality of laser beam pulses to remove a distal layer of the ferrule without removing an optical fiber secured within the ferrule. By removing the distal layer from the ferrule, the optical fiber is caused to protrude distally outwardly from the distal end of the ferrule by a desired amount. A final polish is applied to the distal end face of the ferrule. In some examples, a subsequent laser step is used to remove portions of the distal end face of the ferrule.
