Abstract
A joint for an optical cable has a tapered hollow insert (26) with high friction surfaces (26D) so that after jointing the optical package, the cable strength members (6A 6B) can be clamped onto the high friction surfaces of the insert by a wedging action. The surfaces prevent strength members moving axially and imposing longitudinal strain on the jointed package, and the arrangement is such that the differential strain between the strength member layers are minimized if not eliminated.
