No metal wires are used in an ADSS cable. Optical fibers are either supported in loose buffer tubes, or arranged in a ribbon configuration. To prevent strain on the fibers, most types provide the fibres with

An optical cable so manufactured has a local excess fiber length (EFL) varying of or less than 0.2% along the longitudinal extension of the cable with respect to an average EFL of the cable.
