  • Patent number: 10209447
    Abstract: A micro splice protector for a fusion connection between a pair of optical fibers takes the form of a cylindrical sleeve of dimensions similar to that of the fusion splice itself, with an epoxy material used to encase the fusion splice within the sleeve. The sleeve is formed to exhibit an inner diameter only slightly greater than the outer diameter of the optical fibers, with the length of the sleeve typically formed to be only slightly longer than the stripped end terminations of the pair of fibers being spliced together. The cylindrical sleeve is formed of a rigid, but lightweight, material (e.g., stainless steel, fused silica) and an epoxy material is injected into the configuration to fill any gaps between the fusion connection and the inner surface of the sleeve. The result is relatively stiff fusion splice protector that is extremely small in size and well-suited for use in optical component packages where space is at a minimum.

  • Patent number: 10180541
    Abstract: A fiber optic connector is disclosed that includes a plug body having a plug end and a connector core that mounts within the plug body. The connector core includes a ferrule subassembly including a ferrule, a ferrule hub that attaches to the ferrule, a spring holder and a connector spring. The ferrule sub-assembly is assembled with the connector spring pre-compressed to an initial compressed state prior to mounting the connector core within the connector body. The plug body and the core are configured such that the connector spring is moved from the initial compressed state to a final compressed state when the connector core is loaded in the plug body. In certain examples, tuning features can be integrated into the connector core.

  • Patent number: 10175431
    Abstract: Techniques for reducing optical fiber bending loss in an optical transceiver are disclosed. In an embodiment, a small form-factor (SFF) optical transceiver housing includes a demultiplexer device, such as an arrayed waveguide grating (AWG) device, having a longitudinal center line that is offset laterally by a distance Doffset from the longitudinal center line of the SFF optical transceiver housing. The lateral offset distance Doffset may advantageously enable an intermediate optical fiber coupling the demultiplexer with an optical coupling receptacle, such as an LC connector, to be routed within the SFF optical transceiver housing in a manner that avoids introducing bends that are less than a minimum bending radius associated with the intermediate optical fiber cable. Thus some embodiments of the present disclosure enable greater tolerance when routing an intermediate optical fiber within housings that would otherwise introduce bending loss by virtue of their constrained dimensions.

  • Patent number: 10012800
    Abstract: Improved optical fiber coupling reliability is realized by improving structures and materials used at the fiber joint. When ceramic ferrules are used at the fiber joint, the penetration of a UV-cured optical adhesive between the ceramic ferrules and the fiber ends is avoided or prevented, while an anti-reflective coating, an uncured optical adhesive, or a refractive index matching gel may be applied between the ceramic ferrules. When glass ferrules are used at the fiber joint, the UV-cured optical adhesive may be applied and fully cured between the glass ferrules and the fiber ends.
