Abstract
The invention relates to a positioning ferrule for an optical fibre providing an adjustable connection between two fibres. The positioning ferrule according to the invention comprises detecting means for detecting the uncoupled radiation in the down-side fibre and therefore transmitted in the sheath of the latter. The process for adjusting a connector comprising said ferrule comprises producing a relative displacement of the axes of two fibres so that the detected radiation is minimum. The invention is applicable to long-distance optical telecommunications employing monomode optical fibres.
