Abstract: Disclosed herein is a traceable fiber optic cable assembly with indication of polarity. In particular, the traceable fiber optic cable assembly includes a traceable fiber optic cable, a first duplex connector at a first end of the fiber optic cable, and a second duplex connector at a second end of the fiber optic cable. A first tracing end of the tracing optical fiber is in a preconfigured orientation in the first duplex connector offset from a central axis of the first duplex connector, and a second tracing end of the tracing optical fiber is in a preconfigured orientation in the second duplex connector offset from a central axis of the second duplex connector. The tracing optical fiber receives an optical tracing signal for propagation to the second tracing end of the first tracing optical fiber to indicate a first orientation of the first duplex connector corresponding to a first polarity state of the traceable fiber optic cable assembly.

Abstract: Embodiments of the disclosure are directed to a bend induced light scattering (BIS) optical fiber and method of making. The BIS optical fiber includes a core of pure silica devoid of nanovoids and a cladding surrounding the core. The core has a first index of refraction and the cladding has a second index of refraction that is lower than the first index of refraction of the core. The first index of refraction of the core and the second index of refraction of the cladding are configured to maintain light within the core when the BIS optical fiber is unbent in a light retaining position and to emit light from the core to the cladding at a bend in the BIS optical fiber when the radius of curvature of the bend is less than a critical radius of curvature and the BIS optical fiber is in a light emitting position.

Abstract: An optical coupling system includes a tapered coupling element having a first end opposite a second end, a core having a core diameter that is larger at the first end than at the second end, and a cladding layer that is coupled to and circumscribes the core. An optical pathway is disposed within the core and that extends between the first end and the second end. The tapered coupling element is tapered from the first end to the second end such that the core diameter adiabatically transitions a light beam traveling along the optical pathway from a first beam size at the first end to a second beam size at the second end.

Abstract: A traceable cable and method of forming the same. The cable includes at least one data transmission element, a jacket at least partially surrounding the at least one data transmission element, and a side-emitting optical fiber incorporated with and extending along at least a portion of the length of the cable. The side-emitting optical fiber has a core and a cladding substantially surrounding the core to define an exterior surface. The cladding has spaced apart scattering sites penetrating the exterior surface along the length of the optical fiber. The scattering sites scattering light so that the scattered light is emitted from the side-emitting optical fiber at discrete locations. When light is transmitted through the core, light scattered from the side-emitting optical fiber allows the cable to be traced along at least a portion of the length thereof.

Abstract: A cap apparatus is mounted to a fiber optic connector having a ferrule supporting optical fiber(s). A sealing apparatus is cooperatively configured with the cap apparatus for protecting an end face of the ferrule. The cap apparatus includes a body having opposite ends between which a cavity extends. The opposite ends of the body respectively define first and second openings to the cavity. A portion of the fiber optic connector extends through the first opening and into the cavity. The cap apparatus includes a cover mounted to the body and at least partially obstructing the second opening, wherein the end face of the ferrule is positioned within the cavity at a location spaced from the cover. The sealing apparatus is positioned between at least a portion of the cover and the end face of the ferrule.

The cable includes at least one data transmission element, a jacket at least partially surrounding the at least one data transmission element, and a side-emitting optical fiber incorporated with and extending along at least a portion of the length of the cable.

The scattering sites are capable of scattering light so that the scattered light is emitted from the side-emitting optical fiber at discrete locations proximate to the scattering sites. When light is transmitted through the core, light scattered from the side-emitting optical fiber allows the cable to be traced along at least a portion of the length thereof.
