    摘要: An optical cable for communication includes at least one retaining element blocked with respect to the water propagation as well as a process for manufacturing such an optical cable. The optical cable includes, in addition to the retaining element, at least two transmission elements housed within the retaining element and a water swellable yarn housed within the retaining element. The water swellable yarn is selected according to the following equation: V w V TF = k V t + R ( I ) in which Vw is the volume of the water swellable yarn after swelling upon contact with water; VTF is the total free volume in the retaining element; k is a constant≧180; R is a constant≧1.4; and Vt is the free volume per each transmission element. Advantageously, the optical cable is water-blocked and the water swellable yarn does not induce microbending effects on the transmission elements.

      摘要: A telecommunication fiber optic cable for gas pipeline application has a built-in leakage detecting device. The cable has an optical core including a number of telecommunication optical fibers, an outer jacket covering the optical core, and one or more gas leakage detector optical fibers. One or more gas leakage detector optical fibers are enclosed within the outer jacket. Preferably, the cable has a linearly extending rod reinforcing system having strength rods that force the cable to bend in a preferential bending place. Preferably, the leakage detector optical fibers are located at, or close to, a plane that is substantially orthogonal to the preferential bending plane and passing through the cable neutral axis.

      摘要: Telecommunication cable having an elongated element housing at least one transmitting element. The elongated element has a water-soluble polymeric composition of a vinyl alcohol/vinyl acetate copolymer having a saponification degree of about 60% to about 95%; a plasticizer; a hydrolysis stabilizer compound having a chelant group having two hydrogen atoms bonded to two respective heteroatoms selected from nitrogen, oxygen and sulfur. The two hydrogen atoms have a distance between each other of 4.2×10−10 m to 5.8×10−10 m. The stabilizer compound is present in an amount of at least 0.75 mmoles per 100 g of copolymer. The elongated element is in particular a buffer tube housing a plurality of optical fibers. The presence of the stabilizer reduces the increase of the hydrolysis degree of the copolymer upon aging, thus maintaining the desired water blocking properties of the copolymer.
