Title (EN) OPTICAL CABLE FOR TELECOMMUNICATIONS
(FR) CABLE OPTIQUE DESTINE AUX TELECOMMUNICATIONS
Abstract: front page image
(EN)Optical cable (1) for telecommunications, having low PMD and attenuation values, said cable comprising a central element (4), a plurality of optical fibres (3) and a layer of polymer material (5) devoid of discontinuities and incorporating both the central element (4) and the optical fibres, each of the optical fibres (3) being arranged along an open helix trajectory along which it has a torsion with a mean value of zero and a local maximum value of between 0.05 turns/m and 1.5 turns/m.
(FR)L'invention concerne un câble optique (1) destiné aux télécommunications, ayant une faible dispersion de polarisation de mode et de faibles valeurs d'atténuation. Le câble comporte un élément central (4), plusieurs fibres optiques (3) et une couche de matériau polymère (5) exempt de discontinuités et comprenant l'élément central (4) et les fibres optiques, chacune de ces dernières étant disposées selon une trajectoire en hélice ouverte le long de laquelle la fibre présente une torsion ayant une valeur moyenne de zéro et une valeur maximale locale située entre 0,05 tours/m et 1,5 tours/m.
