A method of forming a multiport optical fibre coupler in which a bundle of seven optical fibres are located in close-packed hexagonal array within a capillary tube and twisted. An optical source is coupled to an outer fibre. A fused, tapered coupler is formed, the tapering being stopped when the minimum of optical power outputs is first maximised. This provides a 6x7 optical fibre coupler. Also disclosed is a 7x7 optical fibre coupler formed by fusing the coupler during formation sufficiently to provide that the maximum insertion loss through the device between any input and output is minimised.

L'invention est une méthode de fabrication de coupleurs de fibres optiques multiport dans laquelle sept fibres optiques formant un faisceau sont placées dans un configuration hexagonale serrée et torsadées à l'intérieur d'un tube capillaire. Une source lumineuse est couplée à une fibre externe. Un coupleur conique thermofixé est formé, la forme conique s'arrêtant au point où le minimum du flux lumineux est maximisé. Ceci donne un coupleur de fibres optiques 6x7. Un coupleur de fibres optiques 7x7 soumis au cours de sa fabrication à une opération de thermofixation suffisamment longue pour minimiser les pertes d'insertion maximales entre une entrée et une sortie quelconques est également divulgué.
