Abstract
An optical fibre-connecting device includes a passageway which is funnel-shaped at both ends thereof and with which an optical fibre is intended to be inserted from either end into the passageway, so that the fibres will meet one another therein. The connecting device (1) includes a first silicon part (7) having a flat surface in which one or more grooves (8) of V-shaped cross-section have been etched. Additionally the connecting device (1) includes a second part (9) which is made of transparent glass and which has a flat side that is intended to abut the grooved surface of the first part (7) so as to form a channel of triangular cross-section, wherein a circle inscribed in the channel will have a diameter which is only slightly larger than the outer diameter of an optical fibre (5, 6).
