Abstract

Viene descritto un procedimento di realizzazione di un cavo per fibre ottiche riunite a nastro, comprendente un nucleo cilindrico (9), dotato sulla sua superficie esterna di scanalature parallele (10) estendentesi elicoidalmente lungo l'asse del cavo, entro cui sono radialmente sovrapposti almeno una coppia di nastri (1). Ogni nastro (1) comprende una pluralità di fibre ottiche (2), ciascuna delle quali è ricoperta da un rivestimento primario stratificato (3), formato da un primo strato (5) a diretto contatto con le fibre (2) con modulo elastico inferiore al modulo elastico di un secondo strato (6) più esterno, e da un rivestimento comune (4) alle fibre ottiche del nastro. Il metodo prevede di deporre i nastri (1) nelle scanalature applicando ad ogni nastro (1a, 1b, 1c, 1d, 1e) una tensione longitudinale maggiore della tensione longitudinale applicata sul nastro ad esso radialmente sovrapposto.
