Abstract

A high degree of precision and an exact positioning of anti-resonant elements in a sufficiently stable and reproducible manner is achieved in that a step of providing a cladding tube includes a processing measure, in which the cladding tube wall is machined with a longitudinal structure extending in the direction of the cladding tube longitudinal axis in the region of the target positions.
