Abstract
An optical cable has a core (1) which comprises at least one optical conductor (7) stranded around a central member (6). The core (1) with the optical conductors (7) is enclosed by a reinforcing layer (2) comprising strength members (11). These strength members (11) are profiled bodies with flat cross section wherein the side faces (12, 13) of adjacent members (11) are in contact with each other and support each other. The strength members (11) form around the core (1) a closed jacket stable against changes of diameter. The optical conductors (7) are stranded around the central member (6) so that after each turn the direction of stranding changes, i.e. one turn to the right, the next to the left, then again to the right, etc. Thereby a wave-like stranding of the optical conductors (7) is formed.
