METHOD AND SEMI-FINISHED PRODUCT FOR PRODUCING A MULTICORE FIBRE

Abstract: a known method for producing a multicore fiber having a marker zone close to the edge comprises a method step in which a component group is reshaped to form the multicore fiber or to form a pre-form for the multicore fiber. in order to provide a method on this basis for producing multicore fibers having a marker zone close to the edge, in which the risk of rejects is reduced, the marker element is arranged on the an outer lateral surface of a glass cladding cylinder, wherein a longitudinal groove is created in the outer lateral surface of the glass cladding region and extending in the direction of a cylinder longitudinal axis, and the marker element is melted in the longitudinal groove before the reshaping to form the pre-form or the multicore fiber.
