Abstract
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.
