PROCESS FOR ALIGNING AN OPTICAL FIBRE IN A BORE, AND DEVICE FOR CARRYING OUT THE PROCESS

摘要

The invention concerns a process and device for eliminating the play between the outer surface of an optical fibre (1) and the inner surface of the bore (22) in an optical-fibre mounting (2). The process proposed does not attempt to adapt the zone surrounding the optical fibre to the external shape of the fibre, as used to be the case, but adapts the optical fibre to the internal shape of the bore (22). The process steps necessary for this include heating the optical fibre (1), then compressing it longitudinally and pulling the compressed section (11) into the mounting (2), bonding the optical fibre (1) with adhesive (7) in the bore (22) and finally, in a separate operation, abrading/polishing the end (12) of the optical fibre and the end (23) of the mounting (2). The process can be used anywhere where the optical fibre can be adapted to the internal shape of the mounting bore by heating and compressing.
