Abstract

Abstract An optical fibre is terminated by securing the fibre with adhesive (41) in a ferrule (16) having a radially deformable end portion (23) with a portion of the optical core (2) from which the cladding (4) has been removed protruding out from the end portion (23) and press fitting a rigid alignment socket (33) having a concentric bore (37) in a transverse end wall (36) onto the end portion (23) of the ferrule (16) with the core (2) received in the bore (37) so that the core (2) is concentric with the periphery of the end portion (23). The exposed portion of the core (2) is removed after the adhesive (41) has set together with the alignment socket (33) and the ferrule end portion (23) press fitted into a suitble bush also receiving a similarly terminated fibre.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 162 words
A method of terminating an end of an optical fibre in which the fibre end is secured by adhesive in a ferrule having a radially deformable end portion, characterised by the steps of removing a portion of optical cladding (4) from an end portion of the fibre to expose a length of optical core (2), inserting the fibre end and adhesive (41) into the ferrule (16) so that the core (2) protrudes out of the ferrule (16) beyond a radially deformable end portion (23) of the ferrule (16) and the cladding (4) extends into the end portion (23); press fitting a rigid alignment socket (33) having a concentric bore (37) in a transverse end wall (36) on the end portion of the ferrule with the core (2) received in the bore (37) so that the core (2) is concentric with the periphery of the end portion (23) and removing the exposed portion of the core (2) after the adhesive (41) has set.
Claim 2
Independent Claim 162 words
A method of terminating an end of an optical fibre in which the fibre end is secured by adhesive in a ferrule having a radially deformable end portion, characterised by the steps of removing a portion of optical cladding (4) from an end portion of the fibre to expose a length of optical core (2), inserting the fibre end and adhesive (41) into the ferrule (16) so that the core (2) protrudes out of the ferrule (16) beyond a radially deformable end portion (23) of the ferrule (16) and the cladding (4) extends into the end portion (23); press fitting a rigid alignment socket (33) having a concentric bore (37) in a transverse end wall (36) on the end portion of the ferrule with the core (2) received in the bore (37) so that the core (2) is concentric with the periphery of the end portion (23) and removing the exposed portion of the core (2) after the adhesive (41) has set.
Claim 3
Dependent Claim 52 words
A method according to Claim 1, characterised by the step of coating the interior of the socket (33) with an adhesive releasable material prior to press fitting onto the ferrule end portion (23) and removing the socket (33) after the adhesive (41) has set and prior to removal of the core (2).
Claim 4
Dependent Claim 48 words
A method according to Claim 1, characterised by the step of removing at least part of the socket (33) simultaneously with removal of the end portion of the core (2) and removing any residue of the socket (33) after removal of the end portion of the core (2).
