1. A continuously transposed cable CTC extending according to a longitudinal development direction (L) and having two opposite longitudinal ends, said CTC cable comprising a plurality of strands arranged so to form at least a first and a second adjacent stacks, each stack extending along the longitudinal development direction (L), wherein said at least first and second stacks form a longitudinal interface (16) therebetween wherein the longitudinal interface comprises one or more optical fibers positioned at the interface between the first and the second stacks,
wherein the CTC cable comprises three groups of optical fibers each comprising a plurality of optical fibers, each optical fiber of the groups of optical fibers having a respective free portion outside the CTC cable and a tip, respectively positioned near the first longitudinal end, in an intermediate position between the first and the second longitudinal end, and near the second longitudinal end.
