Title: Optical switch element
Inventor: HUBERT LE BAIL
IPC: G02B6/35
Filed: 1993-04-20
Abstract: Device for interrupting and re-establishing the passage of a light beam conveyed in an optical fibre. By analogy with certain electrical switches, the present device comprises a pusher mechanism intended to block off a light signal or to allow it to pass. It consists of a body (1) of parallelepipedal shape, in which an element (2), of the same shape but thinner, is to slide. Arranged on either side of the body (1), in the same axis, is an automatic coupler (3) intended to receive each end of an optical fibre (5) in which it is desired to interrupt and re-establish the passage of the light signal conveyed in it. This signal passes through the element (2) via a small section of optical fibre (11). A spring (4), placed at the bottom of the body (1), brings the movable element (2) back into the "rest" position. The device according to the invention is intended to equip control cabinets for equipment specific to fibre optics and it will be actuated, from the front, by the same mechanisms as those used in the electrical industry.
