An all-dielectric self-supporting optical fiber cable utilizes a single layer reverse oscillated lay (ROL) design and includes a fiber count of more than 288 fibers. By arranging buffer tubes in a single layer, the ADSS cable effectively isolates the tensile and thermo strain of the cable in central and outer strength members, thus preventing strain from aerial installation from impairing or otherwise inversely impacting the performance of the optical fibers. Moreover, fibers are loosely housed in bundles to permit fiber movement and further prevent strain on the fibers.
L'invention porte sur un câble autoporteur tout diélectrique (ADSS) à grand nombre de fibres optiques, du type ROL (à couche unique de tors oscillants inversés) et comportant plus de 288 fibres. En disposant les tubes amortisseurs en une seule couche le câble ADSS permet d'isoler les contraintes de traction des contraintes thermiques du câble des éléments résistants centraux et extérieurs, ce qui empêche les contraintes dues à l'installation aérienne d'affecter ou d'avoir un effet inverse sur les performances des fibres optiques. De plus, les fibres groupées de manière lâche en faisceaux peuvent se mouvoir et échapper aux contraintes.
