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 fiber optic connector and cable assembly includes a cable and a fiber optic connector. The connector has a main connector body, a ferrule, a spring for biasing the ferrule, and a spring push for retaining the spring within the main connector body. A crimp band is provided for securing the fiber optic cable to the fiber optic connector. The crimp band includes a first portion securing a cable strength member. The crimp band also includes a second portion crimped down on a jacket of the cable. The crimp band further includes an inner surface having gripping structures for gripping the strength member and/or the jacket.

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 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: 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.

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: A fiber-optic connector ferrule body (10) that includes a depth that extends from a front end (12) to a rear end (14) of the ferrule. The ferrule includes a contact face (16) at the front end of the ferrule. The contact face includes a major dimension that extends along a major axis (X) defined by the contact face and a minor dimension that extends along a minor axis (Y) defined by the contact face. The major and minor axes are perpendicular to one another. The ferrule also defines alignment pin receivers (18) that extend rearwardly from the front end of the ferrule. The alignment pin receivers have tight-fit sections (26) that extend into the ferrule body from the contact face and flex sections (28) that extend from the first transverse cross-sectional shape to the rear end. The first and second transverse cross-sectional profiles define a degree of rotational flexibility between alignment pins (24) received in the alignment pin receivers (18) and the ferrule body (10).
