Abstract
Abstract A submarine cable joint 1 comprises an elongate coupling element 8 each end of which is connected to the annular tensile layer 28 of cables 2, 3 to be joined. Fibre tails 4, 5 from the cables are led out of the coupling element and wound round bobbin 20 for splicing.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
81 words
A method of joining two cables each including an annular tensile layer surrounding at least one optical fibre such method being characterised by first establishing a mechanical connection between the annular tensile layers with a longitudinally extending coupling member with tubular end parts and leading the ends of said fibres outwardly through bores in the side walls of said end parts, and thereafter joining said ends of said fibres outside of said coupling member and then enclosing the thus formed joint.
