Process of manufacturing and assembling a collective optical coupling device onto the end of a bundle of several monomode optical fibers

摘要

The procedure includes the placing an alignment of two optical fibre ribbons (10,20) within the welding device (1A), the first being monomode optical fibres requiring connection and the second being multi-mode graded index fibres. The two sets of fibres are welded together (1B), and the plane of the weld is then aligned with a cutting plane (1C). The fibres are then displaced by a small distance (L) so that the weld moves away from the cutting plane (1D). Finally the multi-mode graded index fibres which now lie across the cutting plane are cut in order to leave a section of graded index multi-mode fibre attached to the end of each monomode fibre.
