<p>An optical fibre cable has a plurality of longitudinally extending closed channels (6) formed in a protective cover, and each bonded by part of the outer wall (5) of the cover, wherein said wall (5) is formed with at least one region (8) of reduced thickness extending along a channel (6) so as to form a line of weakness which facilitates penetration of the cover to give access to the optical fibre (7) or fibres within the channel (6). A rip cord (9) may be embedded in the wall (5) so that by pulling the rip cord (9) a slit (10) is formedin the wall (8).</p> |
