  • Patent number: 9429466
    Abstract: An illustrative distributed acoustic sensing system includes a multi-mode optical fiber cable for distributed sensing and a distributed acoustic sensing interrogator coupled to the multi-mode optical fiber cable via a single mode optical fiber. The interrogator derives distributed acoustic measurements from Rayleigh backscattering light that is initiated with a substantially under-filled launch configuration that is designed to excite only the lowest-order modes of the multi-mode optical fiber. Mode conversion within the multi-mode optical fiber is anticipated to be negligible. For elastic scattering (i.e., Rayleigh scattering), it is further anticipated that the scattered light will be primarily returned in the incident propagation mode, thereby escaping the extraordinarily large coupling loss that would otherwise be expected from coupling a single-mode optical fiber to a multi-mode optical fiber for distributed sensing. Experiments with graded index multi-mode optical fiber have yielded positive results.

  • Patent number: 9429721
    Abstract: A method and system connects multiple cores within one fiber, e.g., a multi-core fiber (MCF), to multiple fibers with single-cores. The single-core fibers can then be terminated by traditional envelopes, such as a single core LC envelope. A connector holds the single-core fibers into a pattern that matches a pattern of all, or a sub group, of the individual cores of the MCF. The single-core fibers may all be terminated to individual connectors to form a fanout or breakout cable. Alternatively, the single-core fibers may extend to another connector wherein the single-core fibers are regrouped into a pattern to mate with the cores of another MCF, hence forming a jumper. One or more of the single core fibers may be terminated along the length of the jumper to form a jumper with one or more tap accesses.

  • Patent number: 9325151
    Abstract: A technique is described for providing compensation for the thermo-optic effect in a large-mode-area optical fiber, filter fiber, or the like. An optical fiber is provided having a refractive index profile with ambient temperature loss characteristics including a low loss for a first type of light and a high loss for a second type of light. A hot region of the fiber connected into an optical system is identified, in which a thermal index gradient is induced in the fiber. The thermal index gradient, in the absence of a compensating index gradient, would result in degradation of the fiber's ambient temperature loss characteristics. The fiber is arranged according to a layout having a position-varying bending diameter. Throughout the identified hot region, the fiber has a compensating bending diameter that induces a compensating index gradient in the fiber.

    Abstract: A connector includes a main body, and a pair of sockets. Each socket includes a pair of opposed resilient walls in the overall configuration of a split tube. The connector also includes a transversely sliding clamp with two tapered slots, located so that one of the sockets passes through each slot. After fiber terminations are pushed into the sockets through the clamp slots, the clamp is slid in a plane across the socket axes so that the narrower ends of the slots engage the opposed split tube resilient walls of each socket. This squeezes each socket so that the opposed split tube resilient walls press against the associated fiber termination and retains it in place. The sockets may have guide slots for guiding clamp movement. The clamp moves in a translational movement, but in another example the clamp rotates in the lateral plane to squeeze the sockets.

  • Patent number: 8801297
    Abstract: Systems and methods are provided that enable a first bank, or array, of multi-optical fiber connector modules disposed in a plug that is mounted on a first structure to be simultaneously blind mated with a second bank of multi-optical fiber connector modules disposed on a receptacle that is mounted on a second structure. As the first and second structures are brought into engagement with one another, passive coarse alignment features on the plug and on the receptacle coarsely align the respective connector modules with one another. Then, as the respective connector modules begin to come into contact with one another, passive fine alignment features on the respective connector modules engage one another to finely align the respective connector modules such that their optical pathways are brought into precise optical alignment with one another.

  • Patent number: 8727634
    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.

  • Publication number: 20140064666
    Abstract: A multi-optical fiber connector module is provided with an unfilled plastic cover that is used to secure the ends of a plurality of optical fibers at precise locations within the connector modules. The cover has deformable features that permanently deform when the cover is secured to a housing of the connector module. The permanent deformations are caused by forces that are exerted on the deformable features by respective unjacketed optical fibers when the cover is secured to the module housing. When the features deform, they partially wrap about the respective unjacketed optical fibers such that the respective fibers are pinned between the respective deformed features and the respective V-shaped grooves of the module housing. This contact between the deformed features, the respective unjacketed optical fibers and the respective V-shaped grooves maintains the respective unjacketed optical fibers in precise locations along respective optical pathways of the connector module.
