ABSTRACT:
An optical fiber cable maintains an outer jacket, at least one optical fiber tube within the jacket and for each optical fiber tube, four optical fibers, arranged in a substantially squared arrangement. The optical fibers are linearly arranged along the length of the cable. The optical fibers are loosely arranged within the fiber tube in such a manner as to allow shifting of the straight optical fibers to conform to a bending of the cable, while being simultaneously constrained such that the straight arranged fibers do not become crossed-over or overlapped during bending.
