Abstract: An optical fiber cable allows for future expansion with blown optical fibers through conduits. The cable assembly includes a central strength member, a conduit, and a buffer tube of optical fibers, all surrounded by an outer jacket. The central strength member may be tubular. While the buffer tube of optical fibers accommodates current capacity requirements, the conduit and possibly the tubular strength member provide paths for blowing additional optical fibers into the cable to meet future capacity needs.

Abstract: A round, compact, optical fiber cable comprises an outer protective jacket of insulating material having a plurality of individual bundles of optical fibers within the outer jacket. Each bundle includes an anti-buckling rod of electrically non-conductive material and encapsulated by a low modulus material. A plurality of optical fibers encapsulated also in a low modulus material is wound on and about the low modulus material encapsulating the rod in a manner that retards contraction and microbending of the optical fibers. Each of the bundles includes one or more protective jackets of electrically, non-conductive material enclosing the plurality of fibers, anti-buckling rod and encapsulating material. Also, means are provided for identifying individual bundles and fibers.
