Abstract
A chamber element for an optical cable includes an opening for waveguides, which opening is defined by a chamber floor and two legs extending therefrom. The legs are shaped so that a resultant radial force proceeds inside the cross section of the legs as the force is directed toward a center axis of the cable.

In an optical cable having a center element and a plurality of individual elongated chamber elements, the individual chamber elements being stranded in a helical fashion onto the outside circumference of the central element, each chamber element having a chamber for the acceptance of light waveguides, each individual chamber element being fashioned with a cross section of a U-shape which does not form a circular sector shape, each chamber being radially outwardly open and laterally limited by shape-stable legs, the improvement comprising each chamber element having a chamber floor extending between said legs and each leg having a structure with a cross section so that a resultant radial force acting at an outer end face of a respective leg proceeds essentially with the cross section of the leg in an extension of the force toward a cable axis in the center element.
A method of forming an optical cable having a center element with a plurality of individual elongated chamber elements stranded in a helical fashion onto the outside circumference of the central element, each elongated chamber element having a chamber defined by a chamber floor and two legs extending therefrom, said method comprising providing the outer element and the plurality of chamber elements and stranding the chamber elements on the center element, said step of providing creating each chamber element with a cross section of a U-shape, which does not form a circular sector shape, each chamber being radially outwardly open and limited by shape-stable legs with each of the legs having a structure with a cross section so that a resultant radial force acting on an outer end face of the leg is directed within a cross section of the leg along an imaginary line to the cable axis in the center element.
