Abstract:
1. A method of forming an optic cable comprising: forming a thin tubular device from a first part, a second part, and a third part that are at least partly arranged within each other; supporting a front end of the first part of the thin tubular device on a first base; guiding the optical fibres by moving the first base in the travel direction of the optical fibres; supporting a front end of a second part and a front end of a third part of the thin tubular device on a second base; guiding the optical fibres by moving the second base in the travel direction of the optical fibres; measuring the force acting on the first base and the second base in the travel direction of the optical fibres; and subtracting the force acting on the first base from the force acting on the second base to determine the friction force between the optical fibres and the thin tubular device guiding the optical fibres.
