Abstract
Each fibre end of a plurality of fibres to be coupled is placed under longitudinal tension coaxially along an axial bore of a precision cylinder body so that the fibre is accurately aligned with the axis of the cylinder surface of the body whereafter the bore of said body is filled with a resin material which will subsequently set hard, and after setting of the resin material the fibre is snapped, after releasing the tension, either within or closely adjacent to, the mass of resin material, at a point where a cleavage has previously been formed.
