    Abstract: A multi-core optical fiber interconnection structure has a first multi-core optical fiber with a slanted end face and a second multi-core optical fiber with a slanted end face. In a state in which the slanted end faces face each other, each of cores of the first multi-core optical fiber is optically coupled to a corresponding one of cores of the second multi-core optical fiber in a one-to-one correspondence relation. The facing condition between the slanted end faces is adjusted so as to minimize variation in core pitches of pairs of the cores each in the one-to-one correspondence relation.

  • Publication number: 20120328244
    Abstract: An optical connecting member realizes an optical connecting between a multi-core fiber and a plurality of single-core fibers by a waveguide part which connects a first end face and a second end face. With the optical connecting member, a connected end which is connected to the first end face is a straight-line portion that is orthogonal to the first end face in each of the plurality of waveguide parts. In addition, a diverged end which is diverged to the second end face is a straight-line portion that is orthogonal to the second end face. Consequently, light that has passed through the waveguide parts is emitted from the first end face and the second end face substantially perpendicularly to the faces, thereby enabling optical connecting loss to be favorably inhibited.

  • 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.

  • Publication number: 20120039569
    Abstract: The invention pertains to a modular optical connection system that permits simple swapping of optical connectors of different form factor types. Furthermore, it allows a single optical connector design of a given form factor to be used to make optical connectors in various different board-to-board configurations, such as orthogonal, coplanar, and backplane. In accordance with the invention, an outer housing is mounted on a board which housing allows two inner housings to mate with each other through the outer housing. A single outer housing can be used with different inner housings adapted to accept various different connector form factors therein and permits the two mating inner housings to float longitudinally within the outer housing. It also allows the two mating inner housings to engage and disengage via simple push engagement and pull disengagement.

  • Patent number: 8047727
    Abstract: A strain-relief assembly for a field-installable fiber optic connector is disclosed, wherein the assembly includes a ferrule holder, an intermediate sleeve, and a crimp sleeve. The ferrule holder back section holds a buffered section of a fiber optic cable, while the ferrule holder front end holds a ferrule and a splice assembly. A stub fiber is held within the ferrule and the splice assembly so as to interface with a section of field optical fiber protruding from the buffered section. The intermediate sleeve engages and generally surrounds a portion of the ferrule holder back section and thus surrounds a portion of the buffered layer. An intermediate sleeve handler may be used to handle the intermediate sleeve and attached the intermediate sleeve to the ferrule holder back section. Stress-relief strands from the fiber optic cable are flared around the outer surface of the intermediate sleeve. A crimp sleeve is placed over the intermediate sleeve to hold the ends of the stress-relief strands in place.
