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 submarine optical cable having a central polymeric buffer tube, said cable being particularly suitable for long-haul repeatered systems. A longitudinal reinforcing element is embedded into the walls of the central polymeric buffer tube which is of relatively small dimensions. The presence of said reinforcing element allows a precise control over the excess fiber length within the buffer tube. This reinforcing element is of relatively small diameter, in order to comply with the requirements of reduced dimensions of the buffer tube. Notwithstanding this relatively small diameter, said longitudinal reinforcing element allows for a good control over the longitudinal shrinkage of the polymeric buffer tube within the submarine cable.
