Abstract
The method for butt-coupling an optical fibre connector comprising a cylindrical ferrule consists of the following steps: a) preparing the head of the optical fibre for insertion into the ferrule; b) applying a thin layer of resin to the fibre, taking care not to soil the cut end of the fibre with said resin; c) inserting said fibre into the sized hole of the cylindrical ferrule; d) by means of an alignment bush, coupling said ferrule to a reference ferrule in which a piece of fibre has been previously housed and fixed such that the end surface of said fibre lies inward of the end surface of the reference ferrule; e) crosslinking the resin.
