摘要:
Installing a fiber distribution system in a building having multiple floors includes routing a feed fiber to a first enclosure located at one of the floors of the building; disposing pre-connectorized ends of distribution fibers within the first enclosure; routing optical ferrules, which terminate second ends of the distribution fibers without connector bodies, through the building via a sheath; accessing the optical ferrules of the distribution fibers at respective floors; attaching connector bodies around the optical ferrules; and disposing the connector bodies within fiber distribution terminals at the appropriate floors.

A closure device for receiving a fiber optic cable includes an enclosure defining a splice chamber configured to accommodate splices to the plurality of optical fibers. The enclosure has a clamp receiving section therein. The closure device further includes a clamping device including a closed end cavity that receives the strength member to limit buckling of a strength member of the cable inserted in the cavity. The clamping device is configured to be removably inserted into the clamp receiving section of the enclosure. The clamp receiving section is configured to fixedly limit movement of the clamping device relative to the enclosure when the clamping device is installed therein to secure the strength member secured in the clamping device to the enclosure.

A sealing assembly (100) for forming a seal about an elongate object (10) includes a resilient seal member (130) and a loading mechanism (160) . The seal member includes an inner wall surface defining a channel (140) to receive the elongate object. The inner wall surface includes at least one annular rib (144) extending into the channel to engage the elongate object. The loading mechanism is adapted to selectively apply a compressive load to the seal member such that the inner wall surface is expanded inwardly to exert a sealing pressure on the elongate object.

Telecommunications terminal blocks (100) for making and breaking connections with a telecommunications conductor include a unitary base (110) that defines a body cavity (132) having a hinge (140) member at an end thereof. In other embodiments a base includes a hinge member on an external surface thereof. First and second connectors (130, 130’) are mounted in the base and extend into the body cavity. A toggle member (120) is rotatably connected to the base at the hinge member. The toggle member has first and second conductor receiving openings (134, 134’) therein and first and second conductor passages (136, 136’) extending from the respective openings past respective ones of the connectors. An environmental sealant material is positioned in the body cavity.

A sealant-filled connector assembly for use with a connector plug includes a connector housing including a unitary body portion defining a body cavity and at least one conductor passage extending through the unitary body portion and communicating with the body cavity. The connector housing defines a connector opening communicating with the body cavity. The connector opening is adapted to receive the connector plug. An electrical conductor extends through the at least one conductor passage and has a contact portion disposed in the body cavity. An environmental sealant is disposed in the body cavity up to a sealant fill level and at least partially covering each the contact portion. The unitary body portion is devoid of openings other than the at least one conductor passage up to at least the sealant fill level.
摘要:
A method of joining articles (2) together with the aid of conductive polymer components. The conductive polymer components are neither heat-recoverable themselves nor fixed to heat-recoverable articles and preferably comprise a sintered ultra-high molecular weight polyethylene which undergoes a dimensional change when heat is generated within it. Specific components useful in joining or modifying articles such as pipes or cables are sealing strips (10), pressure access devices (60), and conductive polymer tapes (20).

A fiber optic cable system includes a fiber optic main cable having a longitudinal central axis and an outer cable sheath. An outer optical fiber tube (105b) is located within the fiber optic main cable proximate the outer cable sheath and including a plurality of optical fibers extending therein and an inner optical fiber tube (105a) is located within the fiber optic main cable closer to the longitudinal central axis of the fiber optic main cable than the outer optical fiber tube and including an optical fiber extending therein. A first splice location in the fiber optic main cable is at a first longitudinal position along the fiber optic main cable. One of the plurality of optical fibers in the outer optical fiber tube is cut at the first splice location. A first section of the cut optical fiber extends from the cut towards a first longitudinal end of the fiber optic main cable and a second section of the cut optical fiber extends from the cut to a second end of the fiber optic main cable that is longitudinally displaced from the first end. A splice at the second end of the fiber optic main cable couples the second section of the cut optical fiber to the optical fiber in the inner optical fiber tube. As such, easier access may be provided to inner tube fibers using sections of the outer
摘要:
A sealing assembly for providing an environmental seal about an elongate member includes a housing (110,120) defining a passage to receive an elongate member (20), a flowable sealant (54) disposed in the passage, a compression mechanism (140) and a trigger mechanism (150). The compression mechanism includes a biasing member. The biasing member is configured to apply a compression load against the sealant and the compression mechanism (140) is configured to force the sealant (54) to flow about the elongate member (20) to provide an environmental seal about the elongate member. The trigger mechanism (150) is configured to selectively actuate the biasing member to apply the compression load to the sealant.
摘要:
An enclosure assembly for use with a fiber optic cable, the cable having a lengthwise cable axis and including a plurality of optical fibers and a jacket surrounding the optical fibers includes an enclosure housing (111) and a cable control clip (150). The enclosure housing defines a chamber to receive the cable. The cable control clip is configured to be inserted through the cable to extend radially between the optical fibers and the jacket to limit contact between the optical fibers and one or more other components of the cable, and to limit displacement of the enclosure housing relative to the cable when the cable control clip is disposed in the chamber.
