  • Patent number: 8628253
    Abstract: An optical connector is provided having a housing with a cavity formed therein through which an optical fiber passes. Within the cavity, a slightly bent, unjacketed portion of the core of the optical fiber is disposed. If conditions are such that pistoning of the core begins to occur, the slightly bent, unjacketed portion of the core straightens, thereby causing the end of the core to remain substantially flush with the end of the ferrule of the connector housing. In this way, the pistoning effect at the end of the fiber is prevented and optical losses associated with the occurrence of the pistoning effect are avoided.

    Abstract: A connector has first and second connector units, each unit incorporating an oil-filled chamber housing one or more contact elements to be joined. At least one connector unit has a face seal assembly which seals the forward end of the contact chamber in the unmated condition. The face seal assembly comprises three elements. One element is an annular elastomeric seal situated radially outward. The two other elements are inner seal elements which are pressed together radially to form a substantially disc-like shape. The resulting disc-like shaped seal fills the central, circular end face opening of the outer annular seal. As the connector units are mated, elements of the elastomeric face seal assembly are displaced, one axially, and others both axially and radially, creating an opening between the oil-filled chambers that is sealed from the outside environment.

    Abstract: Provided herein is a novel approach to simultaneous fiber presence detection and improved laser eye safety of an optical transceiver. The subject optical transceiver is fitted with at least one switch in its receptacle that controls the laser diode and indicates the presence of a fiber (or fibers) within such a receptacle. If a fiber is present within the subject module receptacle, the laser switch is permitted to be “on”, whereas the absence of a fiber will prevent the laser switch from turning on, thereby permitting effective control of the laser at a single point of failure within the entire optical transceiver system. The typical optical transceivers of today exhibit limited optical power output due to eye safety limit criteria.

  • Patent number: 8376628
    Abstract: A stopper 50 is fixed to an optical connector 10, and the optical connector 10 is accommodated in an opening section 21 of a housing 20. The housing 20 is engaged with the stopper 50 so as to be displaceable with respect to the stopper 50 by a predetermined amount in a direction of inserting the optical connector 10 to a receptacle, and the stopper 50 is biased rearward by a coil spring 40 with respect to the housing 20. The free end of a clip piece 15 is placed on the free end of a latch piece 14 of the optical connector 10, and the free end of the clip piece 15 is placed on an inclination surface 23a at the front end of a concave section 23 formed on an inner wall surface of the opening section 21. At the time of detachment from the receptacle, the housing 20 is displaced in a direction to be pulled out against the biasing force of the coil spring 40. Accordingly, the clip piece 15 and the latch piece 14 are pushed down by the inclination surface 23a to release the lock of the latch piece 14.

    Abstract: The optical module includes an optical device mounting substrate 1 and an optical multiplexer/demultiplexer 2. One laser diode and at least one photodetector, which are positioned in the same plane, are mounted on the optical device mounting substrate 1. The optical multiplexer/demultiplexer is prepared by mounting a wavelength-selective filter and a mirror on the front and back surfaces of a transparent substrate. The optical device mounting substrate and the optical multiplexer/demultiplexer are mounted in a package 3 in such a manner that the optical device mounting surface and the filter surface are not parallel to each other. The optical module also includes a first lens, which is positioned near the laser diode or monolithically integrated with the laser diode, and a second lens, which converges light coming out of the optical multiplexer/demultiplexer toward an optical fiber.

    Abstract: An optical connector device has a first connector including a ferrule for holding an optical fiber and a guide portion projecting longer than the ferrule. The optical connector device also has a second connector for receiving an end of the ferrule along an optical axis of the optical fiber. The second connector includes a receiver for receiving the guide portion and a shutter having a cover part. The shutter is movable between a cover position at which the optical axis intersects the cover part and an open position at which the optical axis does not intersect the cover part. The guide portion is operable to move the shutter from the cover position to the open position when the guide portion is received into the receiver.

  • Patent number: 8287191
    Abstract: A blocking member is sized and shaped to be installed beneath a trigger or triggers of a duplex connector. The blocking member prevents depression of the trigger(s) of the duplex connector and hence prevents depression of latches to release the plugs of the duplex connector from mated receptacles. The blocking member does not block actuation of the latches of the duplex connector. Through the use of a tool, the trigger(s) may be bypassed and the latches operated directly by the tool to release the plugs of the duplex connector when mated to receptacles.

  • Patent number: 8272790
    Abstract: A cable connector assembly for outdoor connection to transceivers. Electrical connection between a component of the cable connector assembly and a connector inside an electronic assembly to which the cable connector assembly is attached is made through a force generated by a biasing member within the cable connector assembly. The biasing member may generate the force as the cable connector assembly is attached to an adapter. Once the cable connector assembly is disengaged from the adapter, the force is released, allowing easy removal of the cable connector assembly, without the need to release a latch. In an environmentally sealed connector in which access to a release mechanism may be restricted, such a structure provides ease of use for either electrical or optical connectors.

  • Patent number: 8256970
    Abstract: An improved, reversibly terminable fiber stub connector assembly is provided that can be readily and positively terminated in the field using simple termination tools. This allows repositioning or replacement of fiber optic cable field fibers if termination is not acceptable in performance. The tool may be a hand-held tool, or used in conjunction with a connector support structure to provide simplified and expeditious field termination of fiber optic cables. The cam tool can include a throughbore that enables connection of a patchcord to the stub fiber of the connector during or shortly after termination without removal of the termination tool. Accordingly, field testing of the connection can be made at the site of termination.
