Abstract
An optical fibre connector to connect two optical fibres comprises a ferrule secured to each fibre end, and a clamping sleeve of shape memory effect metal to align and clamp the ferrules. The shape memory effect metal is selected and trained to expand on heating above its transformation temperature. The bore of the clamping sleeve is arranged to make an interference fit with the ferrules when below the transformation temperature, and a clearance fit when above the transformation temperature. An elastic titanium alloy compression sleeve surrounding the clamping sleeve provides for long-term integrity of the connector and reinforces the clamping action of the clamping sleeve when below its transformation temperature.
