ABSTRACT:
When a pair of plastics sheathed glass optical fibres (1, 2) is joined by a fusion splice there is a length of bare fibre between where the original sheathing of one fibre terminates and where that of the other begins. This gap is filled with reinstatement sheathing (5, 5b) which is fused to the original sheathing using a length (4) of heat-shrink tubing as a mould. The heat-shrink tubing is then removed to leave a smooth profile for the spliced fibre.
