Optical fibre installation tool

摘要

An optical communications route is provided between the inside of a customer's premises and a node of an optical telecommunications network. An optical fibre transmission line including at least one optical fibre is moved along first and second pre-installed tubular pathways. The first tubular pathway passes from the inside of the customer's premises to the outside thereof via an aperture in a wall of the premises. The second tubular pathway passes from the outside of the premises to the network node. The optical fibre transmission line is fed through the first tubular pathway by a mechanical pushing process, and the optical fibre transmission line is propelled along the second tubular pathway by fluid drag of a gaseous medium passed through the second tubular pathway towards to the network node.
