  • Cable having conduits for receiving optical fibers
    Patent number: 7027697
    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.
