Method of manufacture of ebauches of ferrules or multi-ferrules and ebauches obtained by this.

摘要

Method of manufacturing ferrule or multiferrule blanks (10) made of a glassy material, possessing at least one bore (11), characterised in that it comprises the following operations: - machining at least two workpieces (1) made of glassy material, these workpieces being called preblanks, each possessing at least one plane face (2), and such that the joining of a plane face (2) of each of the preblanks (1) against a plane face (2) of another of the preblanks (1) forms a workpiece of external surface similar to that of the blank (10); - machining at least one groove (3) in at least one of the plane faces (2), this groove being intended to be joined against another of the plane faces (2), over the entire length of the faces; - joining the preblanks (1) so as to form the blank (10) and the bores (11). The method according to the invention applies to the manufacture of ferrule or multiferrule blanks intended for connecting optical fibres. IMAGE
