Abstract:
A clamp assembly for securing the ends of longitudinal tensile load-bearing elements comprises a pair of rings 1, 2 having complementary tapered surfaces 6, 7. When assembled, one ring 1 seats coaxially inside the other ring 2 and the elements 4 are gripped between the tapered surfaces. The outer, tapered surface 6 of the inner ring 1 is roughened and embedded in the surface of the elements 4 so that load on the elements acts preferentailly to draw the inner ring 1 more tightly against the inner, tapered surface 7 of the outer ring 2. An outer collar 3 engages the outer ring 2 with a flange 13 to retain the assembly. The assembly finds particular application as an armour clamp for a submarine telecommunications cable.

Abstract:
A fiber access terminal includes a drop cable side and a distribution cable side. The sides are separated by a frame to which a variety of cable management and cable connections components may be mounted. Optical fibers are routed from drop and distribution cables through a plurality of routing paths to splice trays for connection to other optical fibers. The terminal includes a base and a dome cover mounted to the base defining an enclosed interior. Passageways between the base and the dome cover are closed by removable covers to limit moisture and animals from accessing an interior of the dome cover. A tether connects the removable covers to the frame. The removable covers include one or more break out regions configured for being removed to receive one or more cables.
Abstract:
An optical fiber distribution assembly (100) is disclosed. The assembly include an enclosure (102) formed by a circular base (106) and a cover (104) joined at waterproof seal. The base includes openings (200,300) configured to accept an input cable (202) and an output cable. The assembly also includes an inner body (120) formed by four panel members (134,136,138,140) to define four quadrants. In one example, the inner body is formed by two panel members positioned perpendicularly to one another. Disposed on the inner body are a plurality of cable management structures including: radius limiters (206), splice trays (234), splitters (250), terminations (280), and connector storage holders (288).
Abstract:
Die Erfindung betrifft eine Vorrichtung zur strukturierten Ablage bzw. Handhabung von Lichtwellenleitern, insbesondere eine Kabelmuffe. Die Kabelmuffe (30) verfügt über einen Rahmen (37) und mehrere Spleiβkassetten (49), wobei an einer Vorderseite (40) und an einer Rückseite (41) des Rahmens (37) jeweils mehrere Splieβkassetten (49) übereinander angeordnet und schwenkbar an den Rahmen (37) befestigt sind. An mindestens einer vertikal verlaufenden Schmalseite (43) des Rahmens (37) sind Faserführungselemente (50) für Lichtwellenleiterfasern befestigt, derart, dass die Lichtwellenleiterfasern im Bereich der oder jeder Schmalseite (43) seitlich neben den Spleiβkassetten (49) geführt sind. Aus einer vertikal verlaufenden Schmalseite (42) des Rahmens (37) ist eine in dem Rahmen (37) geführte Schublade (82) in horizontaler Richtung herausziehbar, wobei die Schublade (82) in hineingeschobener Position zwischen den der Vorderseite (40) und den der Rückseite (41) des Rahmens (37) zugeordneten Spleiβkassetten (49) angeordnet ist, und wobei die Schublade (82) der Ablage ungeschnittener Bündeladern von Lichtwellenleiterfasern dient. Innerhalb der Spleiβkassetten (49) sind Führungskanäle und/oder Führungsrippe derart angeordnet, dass die Lichtwellenleiterfasern innerhalb der Spleiβkassetten (49) kreisförmig geführt sind.
Abstract:
The invention provides for a cold applied oval port seal particularly useful for sealing optical fiber cables. The closure includes two shell members which fit together to define the enclosure edge wedge seals and internal flexible fingers to locate the optical fibers, restrain movement of the sealing material, and provide strain relief along the longitudinal axis of the cables.
Abstract:
A closure (10) includes a cover (4) and seal block (18). A feeder cable pathway and rear cover is provided for separation of feeder cables from drop cables. The organizer (426) in the closure includes an end cap and rear cable storage (190). Cable fixation clips, linear or bendable, can be used individually or daisy chained together. Cable fixation chambers (224, 226) are positioned on top of the gel block (220) housing. The organizer is a click together organizer. Dual heights on cable guides on sides of the groove plate facilitate cable installation. Tray supports with rounded ends prevent looseness of the tray mounts. Other organizers include cable routing features for compact storage.
Abstract:
A fiber optic cable closure (10) is for containing optical fibers of dispersion-managed network (1). The fiber optical cable closure (10) has a housing with a cavity, and at least one bridge optical fiber (42) disposed within the cavity. The bridge optical fiber (42) having a first end configured to optically connect to a first optical fiber with a first dispersion characteristic. A second end of the bridge optical fiber (42) is configured to optically connect with a second optical fiber having a second dispersion characteristic. In one embodiment, the fiber optic cable closure (10) includes a fiber optic cassette within the cavity of the housing when assembled.
Abstract:
A waterproof and air tight fiber cable splice enclosure assembly (10) includes a pair of housing members (20, 22) that are selectively releasably and sealingly clamped to each other to define a first storage volume (24) and at least one keyhole slot connection area (70) cooperative with an associated tie-down strap for connecting an optical fiber bundle to one of the first or second housing members. A set of arcuate wall members (100) are formed on one of the housing members for defining an oval-shaped buffer cable storage space within the housing and an annular auxiliary cable storage space for storing an auxiliary length of optical fiber bundle. An air valve (150) is provided on one of the housing members for directing a flow of air into the storage space of the optical fiber splice case. The air valve (150) is adapted to meter the flow of air into the space to below a predetermined threshold air flow rate. A pressure relief vent is provided on the enclosure to regulate air pressure accumulated within the storage volume to a pressure less than a predetermined maximum pressure threshold.
