Abstract

CE SYSTEME DE TRANSMISSION UTILISE DES FIBRES OPTIQUES DONT LES SECTIONS SONT CONNECTEES AVEC UN MINIMUM DE PERTES DE COUPLAGE. LE CONNECTEUR MAGNETIQUE COMPREND DES MOYENS M, M PROPRES A PRODUIRE UN CHAMP MAGNETIQUE DONT LES LIGNES DE FORCE SONT PARALLELES AUX FIBRES F1, F2, F3; F1, F2, F3 DES CABLES OPTIQUES CO, CO; UNE ENVELOPPE NON FERROMAGNETIQUE C, C COMPORTANT DES GUIDES CYLINDRIQUES PROPRES A RECEVOIR LES FIBRES OPTIQUES; DES MOYENS FERROMATNETIQUES R1, R2, R3; R1, R2, R3 FIXES AUX FIBRES OPTIQUES ET CAPABLES DE PRODUIRE UN EFFET D'ATTRACTION ET D'ALIGNEMENT PRECIS DES EXTREMITES DES FIBRES LE LONG DES LIGNES DE FORCE DU CHAMP MAGNETIQUE.THIS TRANSMISSION SYSTEM USES OPTICAL FIBERS WHOSE SECTIONS ARE CONNECTED WITH A MINIMUM OF COUPLING LOSSES. THE MAGNETIC CONNECTOR INCLUDES M, M MEANS CAPABLE OF PRODUCING A MAGNETIC FIELD OF WHICH THE STRENGTH LINES ARE PARALLEL TO FIBERS F1, F2, F3; F1, F2, F3 OPTICAL CABLES CO, CO; A NON-FERROMAGNETIC ENVELOPE C, C CONTAINING CYLINDRICAL GUIDES SUITABLE FOR RECEIVING OPTICAL FIBERS; FERROMATNETIC MEANS R1, R2, R3; R1, R2, R3 ATTACHED TO OPTICAL FIBERS AND CAPABLE OF PRODUCING AN EFFECT OF PRECISE ATTRACTION AND ALIGNMENT OF THE ENDS OF THE FIBERS ALONG THE MAGNETIC FIELD STRENGTH LINES.
