| 摘要 |
It is disclosed a process for manufacturing an optical fibre unit for air-blown installations comprising: providing a deposition chamber for applying particulate material, said deposition chamber having an inlet end and an outlet end and a longitudinal axis; passing through the deposition chamber an optical fibre assembly comprising at least one optical fibre embedded in an inner layer of cured resin material, and having an outer layer around said inner layer, the outer layer comprising uncured resin material; injecting a flow of fluid and particle material in said chamber in a direction substantially parallel to the chamber longitudinal axis, at an injection speed of 5 m/s at most; perturbing the flow when in said chamber, thus causing the particle material to impact and partially embed into the outer layer of the optical fibre assembly; and curing the outer layer. |
