Abstract
A coupling between two optical fibre cables has a ceramic ferrule at the end of each cable through which its fibre projects. Each fibre is melted into a spherical termination which sits in a frusto-conical recess at the end of the ferrule. A layer of a transparent resilient adhesive lies between the termination and the recess. The ferrules extend respectively into recesses at opposite ends of a ceramic tube which has a passageway coated with a reflecting layer so that radiation from one cable is focussed by its termination on the termination of the other cable and stray radiation is reflected by the reflecting layer.
