Abstract: A fiber optic cable and connector assembly is disclosed. In one aspect, the assembly includes a cable optical fiber, an optical fiber stub and a beam expanding fiber segment optically coupled between the cable optical fiber and the optical fiber stub. The optical fiber stub has a constant mode field diameter along its length and has a larger mode field diameter than the cable optical fiber. In another aspect, a fiber optic cable and connector assembly includes a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including an expanded beam fiber segment supported within the ferrule. The expanded beam fiber segment can be constructed such that the expanded beam fiber segment is polished first and then cleaved to an exact pitch length. The expanded beam fiber segment can be fusion spliced to a single mode optical fiber at a splice location behind the ferrule.

The fiber optic connector also includes a ferrule supporting an end portion of the optical fiber. The ferrule is mounted at the distal end of the main connector body. The fiber optic connector further includes a spring for biasing the ferrule in a distal direction and a spring push for retaining the spring within the main connector body. The spring push is mounted at the proximal end of the main connector body. The spring push includes a main body and a stub that projects proximally outwardly from the main body. A crimp band is provided for securing the fiber optic cable to the fiber optic connector. The crimp band includes a first portion crimped down on the stub. The strength member is secured between the first portion of the crimp band and the stub. The crimp band also includes a second portion crimped down on the jacket of the fiber optic cable. The crimp band further includes an inner surface having gripping structures for gripping the strength member and/or the jacket.

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 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 ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the ferrule has been inserted into the connector body through the side opening.

Abstract: Disclosed herein are devices and methods for cleaning, verifying cleaning, and coating a ferrule end face in a single housing thereby preventing contamination of the ferrule end face and associated optical fiber end face. Also disclosed herein is a fiber optic assembly including a ferrule; an optical fiber extending through the ferrule to an end face of the ferrule; and a coating on the end face of the ferrule protecting the optical fiber. The coating is prepared by curing a vinyl-terminated polydimethylsiloxane with a crosslinker in the presence of a catalyst.

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.
