  • Patent number: 12189199
    Abstract: The present invention provides an optical connector coupled to an optical receptacle, wherein the optical connector comprises an outer housing, a coupling module, and a latch structure. The coupling module is disposed in the outer housing for slidably connecting to the outer housing. When the latch structure is operated at a first position, the optical connector is unable to be taken away from the optical receptacle, and when the latch structure is operated at a second position, the outer housing is allowed to slide relative to the coupling module whereby the optical connector is taken away from the optical receptacle. In another embodiment, the present invention further provides an optical module and an operation method in which a movement for changing the position of the latch structure is operated to lock the optical connector into the optical receptacle or take the optical connector away from the optical receptacle.

The optical plug including sub-modules over-molded over arrays (e.g., ribbons) of the optical fibers. Each sub-module defines notches for receiving latches of the spring assembly when the optical plug is coupled to the first axial end of the optical adapter. Bare optical fibers extend from the plug, pass through the first axial gel block, and enter the fiber mating region when the plug is coupled to the adapter.

  • 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.

  • Patent number: 9285549
    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: 9081151
    Abstract: An optical connector for reducing attenuation in a cable assembly. A support within the connector precludes bending of exposed fiber within the connector that might otherwise occur when the cable assembly is exposed to environmental conditions involving cyclic temperatures. In some embodiments, optical connector assemblies include an optical fiber jacket surrounding a plurality of optical fibers and a support member adjacent to the jacket. The support member includes channels for receiving regions of the optical fibers that are exposed exterior to the optical fiber jacket. The channels of the support member serve to prevent severe bending of the optical fibers which otherwise would give rise to significant signal attenuation. For multi-fiber optical connector assemblies described herein, even during harsh environmental conditions, the signal loss in the optical fibers may be less than about 0.5 dB. The support may be formed as an extension of a ferrule holder.
