Optical fibre breakout

A technique for protecting an optical fibre breakout particularly from a cable 1 comprising a core 2, a plurality of loose fibres 3 and a jacket 5. The jacket 5 and core 2 are stripped back and the fibres encased in protective tubes 7. This may be done one fibre at a time by removing a portion of cable jacket remote from the end and withdrawing each fibre from under the remaining end portion of jacket. The cable may be held in holding tool and the fibres inserted into their protective tubes by means of an insertion tool.
