Abstract
The invention provides a substrate for positioning the end of one or more optical fibres in a reference plane. Each fibre is positioned by means of three right circular cylindrical dowels in a staggered arrangement on the flat trued face of a parallelepiped. The substrate may further comprise a single additional optical fibre bearing against the apertures of the transmission fibres and doing duty as a cylindrical lens for coupling each transmission fibre with the emissive zone of a laser diode.
