Abstract
Abstract An optical fiber cable comprising a core (2) which comprises at least two filaments (21) stranded, at least one optical fiber (1) stranded around the core (2) and a jacket (4,5,6) around the optical fiber (1), wherein the strand pitch of the filaments (21) of the core (2) is greater than that of the optical fiber (1), in which the optical fiber (1) contained is free from elongation strain when the cable is stretched.
