Abstract:
1. Method for installing optical fiber cable comprising the step of running the cable to an outside installation and running a portion of the cable to an inside installation wherein the optical fiber cable comprises: (a) an optical fiber subassembly comprising at least one optical fiber encased in a tight buffer encasement, the optical fiber comprising a core, a cladding and a polymer optical fiber coating, and the tight buffered encasement consisting essentially of a polymer medium tightly fitting to the polymer optical fiber coating, (b) a layer of high-strength polymer yarn surrounding the optical fiber subassembly, thus forming a yarn-wrapped optical fiber subassembly, (c) a rigid strengthening rod extending along a first side of the yarn-wrapped optical fiber subassembly, (d) a rigid strengthening rod extending along a second side of the yarn-wrapped optical fiber subassembly, (e) a cable jacket surrounding the polymer yarn layer and the pair of rigid strengthening rods, the cable jacket having a round cross section, the method further comprising the steps of separating a portion of the optical fiber subassembly from elements (c) (d) and (e), and running the portion to the inside installation.
