Abstract: A multi-layer reinforced and stabilized cable construction comprising a core portion (1, 11) and a non-metallic sheathing portion having barrier and protective layers and two or more outer reinforcement layers. In order for the mechanical and barrier properties of the cable to be controlled, the barrier and protective layers and/or the reinforcement layers (12, 13) are oriented in a controlled manner at different angles by fibrous reinforcements or lamellar barriers.

Abstract: A cable construction comprising at least one package (3) of fibre ribbons, which package consists of at least one fibre ribbon (4) comprising several parallel optical fibres (5) and a covering (6) joining them together, and at least one reinforcing member (7a) extending in the longitudinal direction of the cable. The package (3) of fibre ribbons is arranged in a cavity (2) with an elongated cross-section in the vertical direction such that the natural bending plane (A) of the fibre ribbon package (3) is substantially perpendicular with respect to the longitudinal plane (B) of the cavity. The reinforcing member (7a) is arranged in the cable construction in such a way that the bending plane (D) of the whole cable defined thereby also is substantially perpendicular with respect to the longitudinal plane (B) of the cavity.
