Abstract
A cable including optical fibers (1) surrounded by a sheath (2) comprising at least one layer in which at least two elongate reinforcement members (4) extend, the cross section of the sheath having a substantially oval outline (5) presenting a minor axis (5.1), and the reinforcement members being disposed symmetrically on either side of the minor axis.
Claims1
A cable including optical fibers (1) surrounded by a sheath (2) having a cross-section which has a substantially oval outline (5) presenting a minor axis (5.1) and a major axis (5.2), the sheath comprising at least one layer in which at least two elongate reinforcement members (4) extend, the reinforcement members being disposed symmetrically on either side of the minor axis, wherein said outline (5) has no re-entrant portion and has an ovalization, that is a ratio of twice the difference between a longest dimension taken along said major axis and a shortest dimension taken along said minor axis of the outline over a sum of the longest dimension plus the shortest dimension of the outline (5), which lies in the range of from 1% to 10%.
