Abstract: The measurement of the displacement of an object M which can move along a birefringent monomode optical fibre F is carried out using an emitter E which injects polarised light into this fibre, so that the state of polarisation of this light varies periodically along the latter with a predetermined pitch. A probe S accompanies the moving object M and creates a magnetic field H which modifies this light in a manner depending on its local state of polarisation. A receptor R receives this light at the output from the fibre, detects the modifications therein resulting from the displacement, and as a result calculates the number of steps travelled by the moving object. The invention may be applied to the determination of the position of an underground (metropolitan) railway train.

Abstract: Connecteur pour liaison à fibres optiques. Les fibres de chacun des câbles à connecter sont maintenues dans des canaux formés entre des tiges de maintien cylindriques serrées les unes contre les autres, l'un des ensembles de tiges de maintien étant entouré par des tiges de guidage qui dépassent du côté de l'autre ensemble de tiges de maintien de façon à assurer le guidage de ce dernier lors de la réalisation de la connexion.

Abstract: Fibre-retaining grooves are formed in-between a set of fibre locating pins (M) laid side by side. The pins and a base plane (4) on which they are laid are made of hard, rigid material. Guidance for connection and disconnection is provided by guide pins (G1 to G4) of larger diameter which are therefore robust enough to stand up to handling. The guide pins are in direct contact with the locating pins in order to ensure positional accuracy.

Abstract: In an optical fibre connector, the optical fibre is accurately positioned by clamping it in the channel formed between three parallel rollers each of which bears tangentially on the other two. If the fibre is of exactly the expected diameter such clamping is firm and precise, but given the variation in fibre diameters that must be accommodated there is a danger of there being excessive fibre play. This connector overcomes the problem of fibre tolerances by inserting resilient means in the said channel. Such resilient means may for example be constituted by a set of three resiliently deformable elastomer rings, one mounted on each rod.

Abstract: The invention concerns a connector for optical fibre telecommunication system. The fibres of each of the cables to be connected are held in channels formed between cylindrical holding rods clamped together, one of the sets of holding rods being surrounded by guide rods which extend towards the other set of holding rods so as to ensure the guiding of the latter at the time when the connection is made.
