An optical fibre cable is manufactured by preforming elongate sheath sections (2) and bringing the sections together whilst feeding cable elements such as strength members (3) and coated optical fibres (4) into channels provided in the sheath sections. The sheath sections may be secured together by impact or hot melt adhesive. To enable easy access to the fibres, such as for the application of non-intrusive taps, easy knock-out panels (2a) are provided at intervals along the length of one or both sheath sections before they are joined by, for example, die-stamping. if a mechanical grating is required for a tap it may be embossed or engraved in one sheath section, the other sheath section having knock-out panels aligned with the grating. <IMAGE> |
