A number of optical fibres (1) are formed into ribbons (2), the fibres following an undulating path in the plane of the ribbon. A number of ribbons are then superimposed to form a stack of square section. Each ribbon may be provided with longitudinal reinforcing elements along its edges and a balancing ribbon, comprising reinforcing elements only, added to the top and bottom of the stack. The resulting assembly may be twisted in a helical configuration about its central axis. |
