An optical fibre assembly for blown installation, comprises a fibre unit having at least one optical fibre. The unit has a coating comprising an external layer of a material containing hollow glass beads at least some of which project from the outer surface of the external layer. The coating also has an inner, buffer layer of a material having a lower modulus of elasticity than that of the material of the external layer and an intermediate layer of material disposed between the external and inner layers.
Le dispositif à fibres optiques soufflées comprend un ensemble de fibres comportant au moins une fibre optique. L'ensemble a un revêtement qui comprend une couche externe consistant en un matériau renfermant des grains de verre creux dont au moins quelques-uns font saillie de la surface extérieure de la couche externe. Le revêtement comporte également une couche d'amortissement interne faite d'un matériau possédant un module d'élasticité plus bas que celui du matériau de la couche externe ainsi qu'une couche intermédiaire de matériau placée entre les couches externe et interne.
