    摘要： An optical fiber cable construction includes a first fiber marker which allows one initially to determine a linear length of the optical fiber between first and second points, and a second marker which allows one to determine a linear length of the fiber optical cable between the first and second points, thus ensuring that the length of the fiber initially exceeds the length of the cable during initial installation so as to minimize the chances of excessive temperature induced stress being imposed on the optical fiber during its useful life.

    摘要： In the manufacture of a lightguide fiber cable (21) in which a lightguide fiber core (32) is loosely disposed in a composite sheath 40 it is important to control the ratio of the lengths of the core and sheath. A core which is shorter than the sheath and which follows a shortened path on a reel may be unduly strained when the cable is installed in the field. This problem is overcome by coupling the core to the sheath by a system (25) which includes a constant speed linear capstan (146) and a relatively large variable speed sheave (150) that is positioned between the linear capstan and a takeup reel (154). The coupling of the core to the sheath is accomplished on the sheave after the sheath is elongated between the linear capstan and the sheave. The coupling and the elongation cooperate to compensate for the inherent shortfall in core length which otherwise would occur when the cable is wound on a reel. As a result, when tension forces that have been applied to the sheath are reduced, the sheath, which includes strength members having a relatively high modulus of elasticity, recovers to its original length and the ratio of the length of the core to that of the sheath becomes a predetermined value.

    摘要： An overhead electric conductor with optical fibres loosely housed in the bore of a central core, which bore also contains a greasy water-impermeable medium 4, is manufactured by causing a preformed elongate metal member of U-shaped transverse cross-section and the optical fibres to advance in the direction of their lengths, the rate of advance of the fibres being restrained. As the U-shaped elongate member is transversely folded around the optical fibres greasy water-impermeable medium is injected into the bore of the elongate metal member under a controlled pressure. The consistency of the greasy water-impermeable medium the pressure and rate at which it is injected into the bore and the degree of restraint imparted to the optical fibres 3 is such that, in a predetermined length of the conductor, the length of the optical fibres exceeds the length of the bore by a controlled extent, preferably 1 to 3%.

    摘要： A drop cable includes a jacket, first and second support members, and at least one optical fiber. The jacket has a oval-shaped cavity defined therein, where the minor dimension of the cavity is as small as about 0.25 mm and wherein the major dimension of the cavity is in a range of 0.25 mm to 10 mm. The first and second support members are arranged on opposing sides of the cavity and run generally longitudinally. The optical fiber is within the cavity and has a length greater than a length of the drop cable. Further, the optical fiber is in a substantially serpentine configuration in the cavity, where the serpentine configuration is substantially along a plane defined by a major axis of the oval-shape of the cavity.

    摘要： A method and apparatus for manufacturing an optical cable comprising at least one metal tube housing at least one optical fiber and having a predetermined excess fiber length (EFL) is described. In this method the metal tube is plastically deformed and shortened by a predetermined amount (St) greater than the predetermined EFL and is plastically deformed after shortening to provide a controlled elongation thereof so as to reach the predetermined excess fiber length. An optical cable so manufactured has a local excess fiber length (EFL) varying of or less than 0.2% along the longitudinal extension of the cable with respect to an average EFL of the cable.
