    Abstract: A multi-core plastic optical fiber is used for multi-channel communication purposes. An alignment tool comprising a light source, selective filter and a detachable alignment-tube having a guide notch is provided to map the individual cores of a multi-core plastic optical fiber and prepare the connection of optical transceivers to both exposed ends of a pre-cut length of fiber. The alignment method results in a pre-cut length of fiber having alignment-tubes with guide notches secured to both ends. Transceiver guide projections mate to the notches, creating a complete optical multi-path between the transceiver active elements through the fiber cores. An automatic method of assembling optical transmitters to a multi-core fiber and mating optical receivers uses no alignment tools and tubes. This method dictates a specific placement of the optical transmitters in relation to the cores and receivers, assigning each transmitter to a preferred receiver based on detected light signal criteria.

    Abstract: An optical fiber ribbon holding member capable of readjusting a position of an optical fiber ribbon without requiring a heating operation is provided. A holding member main body that has a U-shaped cross section and a space to which a plurality of optical fiber ribbons can be accommodate in a laminated state, and a lid body an opening surface of which has a reverse U-shaped cross section are employed. A latch structure is formed on wall portions of a lid body and a holding member main body, and engages to each other when the lid body covers the holding member main body. Heating operation is not required, and the optical fiber ribbons are held by only a simple operation of covering the lid body, so that the operation of holding the optical fiber ribbons is easily performed and readjustment of the position of the optical fiber ribbons can be performed.

  • Patent number: 8620130
    Abstract: Pulling grips for installing a fiber optic assembly are disclosed. The pulling grip includes a pulling grip housing for receiving part of a fiber optic assembly therein. The pulling grip may also include a pulling grip sleeve and/or pulling sock. In one embodiment, the pulling grip housing has a friction fit with the pulling grip sleeve when assembled, thereby inhibiting rotation therebetween. Consequently, the friction fit advantageously inhibits twisting of the fiber optic assembly when installing the same using the pulling grip. In this manner, the pulling grip housing can easily be insert into the pulling grip sleeve and removed when pulling of a fiber optic assembly is completed. The pulling grip housing, pulling grip sleeve, and/or pulling sock may also be reused for pulling other fiber optic assemblies.

  • Patent number: 8596886
    Abstract: An apparatus includes an enclosure configured to contain at least one optoelectronic device and to interface the at least one optoelectronic device to a polymer-clad silica (PCS) optical fiber. The enclosure includes a first section that includes a base portion and a wall portion. The wall portion is coupled to the base portion. The wall portion defines an open-ended slot that is configured to receive a first portion of a PCS optical fiber lead extending through the wall portion. A second section is configured to sealingly engage a first edge of the wall portion and the first portion of the PCS optical fiber lead. Passive alignment of PCS optical fiber leads to optoelectronic devices inside the package is accomplished using special designed precision mold ceramic block with integral U-grooves.

  • Publication number: 20130236152
    Abstract: An optical transducer is provided. A “measuring” portion of the transducer may be exposed to a high pressure and fluids when the optical transducer is deployed (e.g., in a wellbore or other industrial setting). The transducer may include an optical waveguide with a first portion that forms a first seal that isolates an “instrumentation” portion of the transducer from exposure to the high pressure and fluids to which the measuring portion may be exposed. The transducer may also include a second seal with a “stack” of material elements that contact a second portion of the optical waveguide to also isolate the instrumentation portion of the transducer from exposure to the high pressure and fluids to which the measuring portion may be exposed.

  • Patent number: 8511908
    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.

  • Patent number: 8488934
    Abstract: The present invention relates to a fiber distribution hub. The fiber distribution hub comprises a base case comprising at least one port portion for introducing an optical cable, wherein the optical cable includes a first fiber; a splitter case releasably attached to the base case; a splice tray rotatably hinged to the splitter case; and a cover engagable with the base case to enclose the splitter case and the splice tray. The first fiber is connected to a second fiber in the splice tray, and the second fiber is connected with a splitter in the splitter case to separate the second fiber into a plurality of separate third fibers. Thus, the invention provides a compact and modular fiber distribution hub. In addition, the fiber distribution hub can join optical fibers by mechanical splices, fusion splices and fiber optic connectors in a single unit.
