Abstract
An optical cable has segment-like chamber elements with openings receiving a stack of waveguide bands characterized by the bands of each stack having a different length to compensate for stresses created by stranding the elements in an optical cable. To obtain the different lengths for each of the waveguide bands in a stack, the cable element is guided over a curved path, such as on a periphery of an insertion disc and the waveguide bands are then introduced into the chamber of the chamber element while in this curved position.
Claims11
A method for manufacturing an optical cable composed of a plurality of chamber elements wrapped around a core, said chamber elements each having a chamber opened at one side of the element for receiving light waveguide bands, said method comprising the steps of providing said chamber elements, each element having a chamber opening on one side, guiding each chamber element in a path having a curved portion, inserting the light waveguide bands into the chamber of the element in the region of said curved path so that the light waveguide band lying furthest toward the outside of the curved path has a greater length than the light waveguide band lying toward the inside of the path, and then, subsequently, stranding the chamber element with like elements helically onto a cable core, which is moving along a cable axis.
