Abstract

Viene descritto 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, almeno una coppia di nastri (1) essendo radialmente sovrapposti all'interno di almeno una di dette scanalature (10). Ogni nastro (1a, 1b, 1c, 1d, 1e) comprende una pluralità di fibre ottiche (2), ciascuna delle quali è ricoperta da un rivestimento primario stratificato (3) e da un rivestimento comune (4) alle fibre ottiche del nastro. Il rivestimento primario (3) è formato da un primo strato (5) a diretto contatto con le fibre (2) e da un secondo strato (6) esterno al primo strato (5), il modulo elastico di detto primo strato (5) essendo inferiore al modulo elastico di detto secondo strato (6). Ad ogni nastro (1a, 1b, lc, 1d, 1e) è applicata una tensione longitudinale, maggiore della tensione longitudinale applicata sul nastro ad esso radialmente sovrapposto.
