Abstract
Abstract In a method for fixing an optical fibre in an optical fibre connector element the fibre is fixed therein by means of centering elements (22) and a curable material (28), for example an adhesive. The centering elements and the curable material are positioned between the envelope of an end portion of the optical fibre (6) and a surface portion (26) of the connector element surrounding said envelope. After the fixing of the fibre end portion in the connector element the end portion of the connector element including the centering elements (22) and the fibre end portion (6) are machined, for example ground, up to a plane (30) which is positioned inside the points of contact between the centering elements (22) and the fibre end portion (6) and between the centering elements (22) and the surface portion (26) of the connector element surrounding the fibre end portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
232 words
A method for mounting and fixing an optical fibre in an optical fibre connector element, in which centering elements are moved into engagement with the envelope of an end portion of the optical fibre as well as with a surface portion of the connector element surrounding said envelope to provide points of contact between the centering elements and the end portion of the optical fibre and further points of contact between the centering elements and said surface portion of the connector element surrounding said envelope and in which the space between the envelope of the fibre end portion and the surface portion of the connector element surrounding said envelope is supplied with a curable material, characterized in that an end portion of the connector element including the centering elements and the fibre end portion is machined away, up to a plane positioned inside the points of contract between the centering elements and the fibre end portion and the further points of contact between the centering elements and the surface portion of the connector element surrounding the fibre end portion, so as to eliminate contact between the centering elements and the optical fibre and between the centering elements and the connector element said machining taking place after the end portion of the optical fibre has been moved into engagement with the centering elements and has been fixed by means of the curable material.
Claim 2
Independent Claim
