摘要： An optical fiber cable (20) includes provisions in a core thereof for preventing the flow of water longitudinally along the core and for preventing freezing of such water. The provisions for preventing freezing of water within the core, which could effect adversely the optical fibers, includes an antifreeze material. Each of two tapes may be impregnated with an antifreeze material such as propylene glycol, for example, and used to provide a laminate with a superabsorbent powder therebetween. Advantageously, the cable may have suitable flame retardance so that it may extend from an outside manhole to distribution points within a building.
摘要翻译：一种光缆（20）包括在其芯部中的装置，用于防止水沿着芯部纵向流动并防止这种水冻结。防止芯内水冻结的措施可能对光纤产生不利影响，其中包括防冻材料。例如，两条带中的每一条都可以用防冻材料例如丙二醇浸渍，并且用于在其间提供超级吸收剂粉末的层压材料。有利的是，电缆可以具有合适的阻燃性，从而可以从外部人孔延伸到建筑物内的分配点。

摘要： An all-dielectric cable (20) which is destined to be buried is provided with at least one electronically resonant marker (44). After the cable is buried, a tradesperson may locate the cable by causing an electromagnetic signal (71), which comprises at least one frequency, to be transmitted by a transceiver (60) and to he induced into the electronically resonant marker associated with the cable. A return signal (73), which is radiated by the electronically resonant marker and which is at a frequency different from the at least one frequency, is received by the transceiver. Characteristics of the return signal provide useful information for the determination of the location of the buried cable.

摘要： Afin de localiser, de suivre, et d'indentifier des objets allongés cachés (12), tels que des câbles à fibre optique enterrés, lesdits objets (12) sont munis de dispositifs d'identification à aimants permanents allongés dont les champs magnétiques peuvent être détectés à une certaine distance desdits objets. Dans un mode de réalisation, ledit dispositif d'identification comprend une bande allongée (10) magnétisée dans le sens de sa largeur, et ayant la forme d'une hélice à pas long, produisant "une signature de champ magnétique" caractéristique permettant la détection et l'identification de l'objet, à l'aide d'un gradiomètre portatif (14) déplacé sur la surface de la terre le long d'une ligne sensiblement parallèle à la longueur de l'objet. Ce mode de réalisation peut produire un champ magnétique diminuant avec le carré de la distance à partir dudit dispositif d'identification (à la place habituellement du cube de la distance), permettant ainsi une détection à des distances importantes. Dans un second mode de réalisation des signatures de champ magnétique distinctives sont produites par des réseaux d'aimants permanents espacés (M), dont les champs magnétiques s'additionnent et se soustraient afin de produire des champs magnétiques comportant des sommets et des vallées le long d'une ligne sensiblement parallèle à la longueur de l'objet.

摘要： A traceable cable (3) and method of forming the same. The cable includes at least one data transmission element (7), a jacket (10) at least partially surrounding the at least one data transmission element, and a side-emitting optical fiber (20) incorporated with and extending along at least a portion of the length of the cable. The side-emitting optical fiber can have a core (31), spaced apart scattering sites (40) having scattering material (42) disposed on an exterior surface of the core along the length of the optical fiber, and a cladding (35) substantially surrounding the core and the scattering material. 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.

摘要： An optical cable includes an optical core and sheath enclosing the optical core. The optical core includes a number of optical units having respective colors and being wound about a longitudinal axis of the cable. The sheath includes at least one non opaque longitudinal section through which a sequence of colors of the optical units is visible from outside the cable. The color sequence acts as an identifier for the cable. The cable may therefore be easily identified (e.g. amongst other cables laid down within the same duct) by a simple visual inspection of the cable's inner structure through the non opaque section(s) of its external sheath.

摘要： A system for use in installation of blown fibre for detecting a signal indicative of presence of at least one of a gas flow or an optical fibre at a remote location, comprising a gas vibration detector (30) configured to acoustically couple with an installation duct through which the signal can travel after its generation at the remote location, and a processor (24) arranged to receive an input from the vibration detector and to process the input to identify the signal present within the input; and a sensor (30) for generating the signal upon sensing the presence of at least one of the gas flow or the optical fibre at the remote location. This avoids the need for human presence at the remote end. The signal may be provided by a whistle mounted on the remote end of the installation duct. The vibration sensor is typically a microphone. Such an arrangement permits the use of simple and low cost equipment at the remote end, avoiding the need for any radio or optical communication system to transmit the remote end condition back to the head end.

摘要： Disclosed are fiber optic cables and assemblies for routing optical networks closer to the subscriber. The fiber optic cables have a robust design that is versatile by allowing use in aerial application with a pressure clamp along with use in buried and/or duct applications. Additionally, the fiber optic cables and assemblies have a relatively large slack storage capacity for excess length. Assemblies include hardened connectors and/or optical connectors such as plugs and/or receptacles suitable for outdoor plant applications attached to one or more ends of the fiber optic cables for plug and play connectivity.
