Abstract
The present disclosure relates to a telecommunications cable having a layer constructed to resist post-extrusion shrinkage. The layer includes a plurality of discrete shrinkage-reduction members embedded within a base material. The shrinkage-reduction members can be made of a liquid crystal polymer. The disclosure also relates to a method for manufacturing telecommunications cables having layers adapted to resist post-extrusion shrinkage.
Claims8
A telecommunications cable comprising:
- at least one optical fiber for carrying a telecommunications signal, wherein the optical fiber includes a core surrounded by a cladding and at least one protective coating;
- a buffer surrounding the at least one optical fiber;
- and
- a layer external to the buffer, wherein the layer includes a thermoplastic base material and a plurality of discrete, elongated shrinkage-reduction members embedded within the base material for resisting shrinkage of the base material, the shrinkage-reduction members having lengths ranging between 0.2 mm and 100 mm, the shrinkage-reduction members including liquid crystal polymers that constitute less than 2% of the layer by weight.
