Abstract
An optical fibre cable comprises a support structure having helical grooves around its periphery. Optical fibres are laid in the grooves. Said fibre-containing grooves (2) are then partially untwisted in the direction of the arrow (4), thereby lengthening the pitch of the grooves and hence lengthening the fibres relative to the grooves.
