摘要: An optical fiber cable includes a flexible pipe of a plastics material (14), and a group of optical fibers (18) loosely mounted within an axial bore of the pipe and held in contact with an inner surface (16) of a peripheral wall of the pipe. At least one elongated flexible reinforcing member (20) is embedded in the peripheal wall of the pipe and extends along a longitudinal axis of the cable, the reinforcing member being disposed in the vicinity of the group of optical fibers and made of a material having a higher Young's modulus than that of the plastics material of which the pipe is made. The optical fiber cable has a neutral axis (G) extending through the bore of the pipe and defining a line of zero stress when the cable is bent longitudinally in a direction (Y) to dispose the reinforcing member radially inwardly of the group of optical fibers. The group of optical fibers are disposed on the neutral axis, so that the optical fibers are not subjected to axial construction or elongation when the cable is bent in that direction.

摘要: 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.
