  • Patent number: 8917968
    Abstract: Embodiments disclosed herein include furcation plugs having segregated channels to guide epoxy into passageways for optical fiber furcation, and related assemblies and methods. The furcation plugs secure furcated fiber optic cables to fiber optic equipment to prevent the furcated fiber optic cables from being damaged. The furcation plugs, as part of fiber optic furcation assemblies, are typically installed on fiber optic equipment that provides fiber optic components to which the optical fibers are connected. The fiber optic cables may be inserted into fiber passageways of the furcation plugs and secured to the furcation plugs with epoxy. The epoxy may be guided into the fiber passageways through segregated epoxy channels of the furcation plug. In this manner, epoxy may be more uniformly distributed within the fiber passageway to improve the epoxy bonds by reducing the occurrence of air pockets known as voids, which can weaken the epoxy bonds and cause attenuation.

    Abstract: A fiber optic connector includes a shroud, spring, ferrule mount, shrink tube, and ferrule. The connector terminates a fiber optic cable including an optical fiber and a strength member. The ferrule terminates the optical fiber and is mounted to the ferrule mount. The ferrule mount attaches to the strength member and includes an exterior retaining surface and a passage for the optical fiber. The shroud is mounted over the ferrule mount and includes an interior retaining surface. The exterior and the interior retaining surfaces engage to limit distal movement of the shroud relative to the ferrule mount and the attached cable. The spring engages the cable and the shroud and distally urges the shroud relative to the cable. The shrink tube forms a seal between the shroud and the cable and can proximally urge the shroud relative to the ferrule mount. This proximal urging is overcome by the spring.

  • Patent number: 8849085
    Abstract: A flexible dust cover is provided for use with a parallel optical communications module for preventing airborne matter, such as dirt, dust, and gases from entering the module. The flexible dust cover fits snugly to the module to protect components of the module and the optical pathways of the module from airborne matter. The flexible dust cover has an elasticity that allows it to be temporarily deformed from its original shape to a stretched state by application of a stretching force to enable the module to be inserted into a central opening formed in the cover. The force is then removed, causing the cover to attempt to return to its original, non-stretched shape. When this happens, interior surfaces of the cover form a snug fit about exterior surfaces of the module. This snug fit fills in air gaps in the module that would otherwise be exposed to the environment.

In one example embodiment, the optical fiber termination reduces reflections into the one or more cores to a return loss of ?70 dB or less regardless of the presence of surfaces proximate the optical fiber termination. At the same time, a length of the optical fiber termination is less than 5 mm and a largest transverse dimension of the optical fiber termination is less than 325 um. The optical fiber termination is useful in fiber sensing applications in general and is particularly effective for terminating a multi-core fiber used in a distributed shape sensing application.

  • Patent number: 8727638
    Abstract: A fiber channel-interchangeable fiber optic connector includes an adapter, two connectors respectively rotatably mounted in respective axle holes at the front side of the adapter, a sub-assembly detachably attached to the adapter to stop the connectors from rotation and hold down the connectors in position, and a cable inserted through the sub-assembly and mounted in the adapter with two optical-fiber cores therein respectively inserted into ferrules of the connectors. Detaching the sub-assembly from the adapter allows rotation of the connectors and the sub-assembly through 180-degrees angle relative to the adapter to interchange the fiber channels.

  • Publication number: 20140126873
    Abstract: Embodiments disclosed herein include furcation plugs having segregated channels to guide epoxy into passageways for optical fiber furcation, and related assemblies and methods. The furcation plugs secure furcated fiber optic cables to fiber optic equipment to prevent the furcated fiber optic cables from being damaged. The furcation plugs, as part of fiber optic furcation assemblies, are typically installed on fiber optic equipment that provides fiber optic components to which the optical fibers are connected. The fiber optic cables may be inserted into fiber passageways of the furcation plugs and secured to the furcation plugs with epoxy. The epoxy may be guided into the fiber passageways through segregated epoxy channels of the furcation plug. In this manner, epoxy may be more uniformly distributed within the fiber passageway to improve the epoxy bonds by reducing the occurrence of air pockets known as voids, which can weaken the epoxy bonds and cause attenuation.

    Abstract: An inserting and extracting motion of an optical plug can be easily carried out via a knob, even in a narrow space. An optical connector plug is provided with a stopper guide in a rear portion of an upper surface of a knob to which an optical plug is installed, a spring guide, an outer cover which is provided in an outer surface of the knob, and a spring which is arranged in between the stopper guide and the outer cover. In the optical connector plug, the outer cover is pressed by an optical connector adapter so as to move backward while compressing the spring, whereby a shutter is opened and the optical plug is allowed to protrude forward from the outer cover. The optical connector plug is provided with a grip portion which protrudes up and down and right and left from a rear end portion of the knob.

  • Patent number: 8714837
    Abstract: An optical fiber connector includes a circular polarizer, an optical electrical converter, and a transceiving module. The circular polarizer receives external optical signals from an optical fiber and divides the received optical signals into first optical signals and second optical signals. The optical electrical converter converts the first optical signals into first electrical signals. The transceiving module receives third electrical signals from ports of an optical communication device, and includes an optical electrical converting circuit and an electrical optical converting circuit. The optical electrical converting circuit converts the second optical signals into second electrical signals and transmits the second electrical signals to the optical communication device. The electrical optical converting circuit converts the third electrical signals into third optical signals and transmits the third optical signals to the optical fiber.

  • Patent number: 8718434
    Abstract: This disclosure describes a fiber optic enclosure in which a cable entry port is sealed using a wedge that compresses a gasket that surrounds a fiber optic cable. As described herein, a fiber optic enclosure may include one or more entry ports through which fiber optic cables pass. As one of the fiber optic cables passes through one of the entry ports, the fiber optic cable passes through a gasket located in a receptacle behind the cable entry port. A wedge compresses the gasket, thereby compressing the gasket. When the gasket is compressed, the gasket exerts radial pressure on the fiber optic cable. In this way, the gasket forms a seal around the fiber optic cable.
