Abstract
Loose tube fiber optic cable containing a core of S-Z stranded strands comprising optical fibers having first and second alternatively repeating first and second sections, and a sheath circumscribing the core. The ROL transition points defined by the junctures of first and second strand sections along the length of the cable have been provided at an optimized reduced distance therebetween that is approximately 1/2 of the longitudinal length of the sheath entry window created during mid-span entry of the loose tube fiber optic cable. Thus, at least one (1) ROL transition point will be located within the sheath entry window during mid-span entry access to the cable, and most suitably either two (2) or three (3) ROL transition points will be located.
