ABSTRACT:
Opposite ends of a fibre-optic cable have terminations including a metal diaphragm which is welded or brazed at its outer edge to the termination. The diaphragm has a central aperture into which extends the ends of a bundle of optical fibres, the fibres being hermetically sealed together at their end and sealed in the aperture by a glass seal. The diaphragm tapers in thickness from its outer edge to its central aperture where it is thinner and is flexible to accommodate relative displacement between the fibre bundle and the sheath of the cable.
