PROCEDURES FOR THE TRAINING OF AN OPTICAL WORLD LEADING PHASE AND PROCEDURES FOR THE PRODUCTION OF AN OPTICAL WORLD LEADING PHASE

摘要

A prior art method of cutting optical fibres (2) calls for the fibre (2) to be held firmly to prevent it from yielding, placed under tension and a scratch made on its surface. The microdiscontinuity thus produced propagates diametrically across the fibre to form a parting plane. There is a danger, however, that undesirable cracks or discontinuities spread out in the longitudinal direction in the fibre (2). The invention calls for the parting plane to be produced by a particle beam (21) aimed at the fibre (2).
