    摘要: A flexible optical circuit includes a plurality of optical fibers mounted to a flexible porous substrate. The optical fibers and flexible porous substrate are thereafter encapsulated with a protective encapsulating material. The encapsulating material can be a liquid which surrounds the optical fibers and flows through pores in the porous substrate to achieve a structurally sound and protected flexible optical circuit. Because the encapsulating material surrounds and protects the optical fibers, heat and pressure are not required in forming the optical circuit, resulting in minimal optical fiber breakage. Additionally, optical fibers may be positioned between two porous substrates, and the fibers and both of the porous substrates then encapsulated by an encapsulating material. A method of constructing the optical circuits includes providing a flexible porous substrate with an upper surface and a lower surface, causing optical fibers to adhere to the upper surface of the flexible porous substrate, and applying an encapsulating material to the optical fibers and the flexible porous substrate to provide strength and protection to the optical circuit. The encapsulating material can be applied to the optical circuit by spray-coating the optical fiber and the flexible porous substrate or by dipping the optical circuit into a bath of encapsulating material.

    摘要: The invention is as defined by the claims. Embodiments of the invention include an optical fiber ferrule, a method of making an optical fiber ferrule and an optical fiber communication system in which at least one optical fiber ferrule has a body with an axially-extending bore formed therethrough at a location radially offset from the longitudinal axis or axis of symmetry of the ferrule body. The offset bore provides for the core of an optical fiber subsequently positioned therein to be slightly offset with respect to the core of an optical fiber positioned within a conventional ferrule aligned therewith. The offset alignment between the two optical fibers is useful in establishing an offset launch condition, which improves bandwidth performance of an optical system, for example, an optical system having a launching single-mode fiber coupled to a receiving multimode fiber. Embodiments of the invention provide an radial offset that is lateral, vertical or a combination of both. Also, for offset launch conditions comprising a single-mode optical fiber launching into a multimode optical fiber, the radial offset is the result of an offset bore in the single-mode ferrule, the multimode ferrule or a resulting combination of offset bores in both ferrules.

    摘要: Embodiments of the invention include an optical communications system including an apparatus and method for laterally displacing or otherwise steering optical signals passing therethrough. The system comprises a launching device for launching or transmitting an optical signal, a receiving device for receiving an optical signal, and at least one optical guiding element. The optical guiding element is a transmission medium that captures and transmits optical information therethrough and is configured, for example, via end geometries, to redirect a portion of light propagating in a first direction and entering the first end substantially along its transmission axis and to redirect light propagating along the transmission axis out of the second end in a desired direction, for example, a second direction laterally displaced from the first direction. Embodiments include angled faces with or without reflective coatings and attached lenses opposing the angled faces. A pair of optical guiding elements is used to laterally displace a launched signal path and a receiving signal path in such a way that the distance between the transmission axes of the launched and received signal paths is increased or decreased, depending on the arrangement. Other embodiments of the invention include optical information splitting arrangements and optical information multiplexing arrangements using a plurality of optical guiding elements coupled between one or more optical signal launching elements and one or more optical receiving devices.

    摘要: The invention is as defined by the claims. Embodiments of the invention include a transfer molding method and mold apparatus for manufacturing optical fiber connectors made of plastic such as mechanical transfer (MT) connectors. The inventive method includes improved optical fiber coupling accuracy by compensating for molding induced shrinkage more accurately than conventional manufacturing. In particular, the transfer molding method includes providing a mold with inverse connector features that are dimensioned and spaced to compensate for differential shrinkage that occurs during processing. The degree of dimensioning and spacing is determined, for example, by experimental processes using similar molding parameters. Once the mold is provided, the core pins are positioned in the appropriate mold features and the mold is filled with a material to be cured into one or more connectors. After curing, the core pins are removed from the molded connector and the molded connector is removed from the mold. The resulting connector has features whose dimensions and spacing align better with other connectors made by similar processing thereby providing improved optical fiber coupling efficiency by compensating for molding induced shrinkage more accurately than conventional manufacturing processes.

    摘要: The present invention is an optical harness and method for an optical cross-connect. The optical harness is defined primarily by a first portion and a second portion. The first portion of the optical harness comprises a number M of fiber optic row cables where each fiber optic row cable comprises an array of a number N of fiber optics arranged on a first plane. The first plane on which each fiber optic row cable is disposed is substantially parallel to each of the other first planes on which a fiber optic row cable is disposed. The second portion of the optical harness comprises a number N of fiber optic column cables where each fiber optic column cable comprises an array of a number M of fiber optics arranged on a second plane. Each fiber optic column cable is disposed on a second plane being substantially parallel to each of the other second planes on which each other fiber optic column cable is disposed. The optical harness further comprises a holding mechanism disposed intermediate the first portion and the second portion of the optical harness. The orientation of the first planes on which the fiber optic row cables are disposed is arranged at a defined angle relative to the second plane on which the fiber optic column cables are disposed. The holding mechanism is arranged and configured to transition the fibers from one configuration toward the first portion to the second configuration toward the second portion and to prevent the separation of the fibers from the optical fiber row cables from progressing toward the first portion of the optical harness. The method for providing an optical cross-connect between a first element and a second element comprises providing the optical harness with connectors disposed on free ends of each of the fiber optic row cables and each of the fiber optic column cables. The fiber optic row cable connectors can be placed in communication with first element, and the fiber optic column cable connectors can be placed in communication with the second element.

    摘要: The invention is as defined by the claims. Embodiments of the invention include an optical fiber connector that supports a linear array or ribbon array of optical fibers. The connector includes a pair of intermatable housing members that, when mated, define a connector having a front end suitable for butt coupling to other connectors or compatible connections, a back end for terminating an array of optical fibers, and a plurality of waveguides or optical fiber support grooves extending from the front end to the back end. According to embodiments of the invention, the back end has at least one feature that increases the opening formed by the housing members at the back end of the connector, thus making it easier to terminate an optical fiber or array of optical fibers therein that optically couples to the waveguide or optical fibers terminated in the front end. For example, one or both housing members include a beveled or curvelinear portion, both of which increase the opening between the housing members at the back end of the connector. Alternative embodiments include methods for using such optical fiber connectors in an optical fiber communication system, methods for making such optical fiber connectors and optical waveguide systems employing such optical fiber connectors.
