Abstract
An optical cable is assembled by inserting dielectric optical waveguides into a filament having periodically reversing helical grooves. Dielectric optical waveguide is unwound from fixed reels by movement of the filament past the reels. A rotatable guide unit has flexible tubes through which dielectric optical waveguide is guided, the tube ends being disposed within the grooves so that respective dielectric optical waveguides and grooves are maintained circumferentially coincident.
