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.

摘要： Optical core for a telecommunications cable comprising at least one support consisting of a central reinforcing member and a first coating layer of a thermoplastic polymer applied around the central member, a plurality of optical fibres arranged around the support and a second coating layer extruded around the support. The optical fibres, in each transverse section of the core, are arranged substantially tangential to the support and, around their remaining portion, are completely encapsulated in the second coating layer. The core can be built using a process wherein the fibres are guided inside appropriate grooves to give conditions of substantial tangency to the support as far as the zone of extrusion.
