Abstract

Cavo ottico con almeno un nastrino di foto - guide e procedimento per la sua fabbricazione.Il cavo ottico presenta almeno un nastrino di foto - guide (LB1), quale contiene più foto - guide (LW1-LW12) racchiuse da un involucro (UH) in comune. Almeno una parte delle foto - guide nell'involucro in comune (UH) è sollecitata con una sollecitazione preliminare meccanica (PP1-PP12) la cui direzione è scelta in modo tale da risultare opposta alla direzione della sollecitazione SP1-SP12 provocata dalla guida in una pista comportante una torsione.(Figura 1).Optical cable with at least one ribbon of photo - guides and procedure for its manufacture. The optical cable has at least one ribbon of photo - guides (LB1), which contains multiple photo - guides (LW1-LW12) enclosed by a casing (UH) in common. At least a part of the photo - guides in the common enclosure (UH) is stressed with a mechanical preliminary stress (PP1-PP12) whose direction is chosen in such a way as to be opposite to the direction of the stress SP1-SP12 caused by driving in a track involving a twist (Figure 1).
