Abstract: The present invention relates to a disconnectable collimation assembly designed to transmit a light beam toward a device to be connected. The assembly comprises a base having a plane of reference strictly parallel to a plane of reference of the device to be connected, a sleeve mounted in the base and supporting a centering device holding a bar-lens, the lens being adjusted so that its optical axis will be in a predetermined position relative to the plane of reference.

Abstract: A cleaning tool for an optical surface, particularly well adapted to the cleaning of optical surfaces which access is difficult.The cleaning tool includes an injector (8) which can send a cleaning liquid, and then a drying gas, under pressure onto the optical surface (2), and a jacket (9) for the evacuation of the cleaning and drying fluids. The tool has a neck (13) to fit onto an optical tip associated with an optical fiber.

Abstract: This invention concerns a device to spread out flat the fibres of an optical cable, which has first been stripped, so that the fibres can be cut across precisely aligned cross-sections, thereby allowing them to be butt-jointed individually with the fibres of another cable, in a splicing operation.This device comprises hand-operated mechanical means of inserting blades, positioned on a diametrical plane of the cable, to separate the fibres into two groups. One blade acts as a stop, while the first group of fibres is being gathered into the notches of one comb, while the other blade performs the same function for a second comb. The combs and blades are then made to rotate in opposite directions, flattening out the group of fibres on a horizontal plane.This device can be applied to optical fibres used for telecommunications.
