ABSTRACT:
A circularly symmetric reinstatement sheathed optical fibre splice butt joining the ends of two acrylate sheathed glass optical fibres is made by a method that includes the step of immersing the spliced fibres (14) in dichloromethane (64) to cause the acrylate to swell and longitudinally expand to close the gap (42) in the sheathing (41) left by the splicing process. The sheathing is clamped in this position while the solvent evaporates. The residual gap, which is comparable in length with the sheath diameter, is protected by the application of a drop of uncured resin which capillary forces constrain to assume a circularly symmetric form until the resin is cured.
