Abstract

An optical cable is assembled by inserting dielectric optical waveguides 11 into a filament 2 having periodically reversing helical grooves 3. Dielectric optical waveguide is unwound from fixed reels 12 by movement of the filament past the reels. A rotatable guide unit 23 has flexible tubes 26 through which dielectric optical waveguide is guided, the tube ends 27 being disposed within the grooves so that respective dielectric optical waveguides and grooves are maintained circumferentially coincident. A number of devices are described for reducing longitudinal tension in dielectric optical waveguides disposed within the grooves. <IMAGE>
