    Abstract: A multipart end-piece adaptor that holds a fiber for stripping, cleaning and splicing that converts into a protective housing for the spliced fiber includes a first adaptor part having a guide sleeve and a second adaptor part that cooperates with the first adaptor part, the second adaptor part having a stripping apparatus. The second adaptor part can be a consumable that, once actuated and removed to strip the fiber, cut the fiber and clean the fiber in one action may be discarded. A further adaptor part engages two first adaptor parts with a guide opening for a coated optical fiber to form a protective housing around the spliced optical fiber.

  • Patent number: 8081857
    Abstract: A fiber distribution terminal having an environmentally sealed enclosure. A spool contained in the enclosure is a spool for housing input fiber cable. The spool is capable of rotation within the housing. An adapter pack and an adapter plate are contained in the enclosure. The adapter pack insures that the connections between fibers of the input fiber cable and fibers of the output fiber cable are secure and organized. The adapter plate guides the routing of both the input and output fiber cables internal to the enclosure. The fiber distribution terminal also includes a spool lock as part of the internal components of the enclosure. The spool lock is engaged to direct the cable routing to a first side or a second side of the fiber distribution terminal.

  • Patent number: 8055114
    Abstract: A cable sleeve for the structured storage and handling of optical waveguides guided in optical waveguide cables is disclosed. The cable sleeve comprises a covering body, which defines an interior. The cable sleeve also comprises a sealing body comprising two dimensionally stable end pieces and a compressible gel element arranged between the end pieces. The sealing body is adapted to be inserted into an opening of the covering body and is operable for feeding optical waveguide cables into the interior and/or for feeding optical waveguide cables out of the interior. The sealing body bears against a stop with an inner one of the two dimensionally stable end pieces. A locking body can be screwed to an outer one of the two dimensionally stable end pieces of the sealing body while compressing the gel element. At least one compensation element is operable for storing the force applied via the locking body and exerting a compression force onto the gel element.
