    摘要： A bonded optical fiber array (20) includes a parallel coplanar array of longitudinally extending contacting optical fibers (22-22). Each optical fiber is enclosed in inner and outer layers of coating materials and is provided with a color identifier. The inner layer is comprised of a UV curable bonding material having a modulus in the range of about 1 M Pa. For mechanical protection, the outer layer is a UV curable bonding material having a modulus in the range of about 1 GPa. When the optical fibers are disposed in the parallel array, interstices are created between the fibers and between the fibers and a envelope which is spaced no further than about 25 µm at its closest point to each fiber. A UV curable matrix bonding material which has a modulus having a value less than that of the outer coating layer on the fiber and more than that of the inner coating layer fills the interstices, extends to the peripheral line which defines the envelope and bonds together the optical fibers. The modulus of the matrix material and the bond of the matrix material to the color identifier on the optical fibers is such that interfiber and interribbon movement is allowed. Also, accessing of the individual fibers is allowed upon the application of peeling forces by a craftsperson without the need for complex tools and without obfuscating the color identifier.

    摘要： A filler rod for occupying space in a stranded optical fiber communications cable having at least one buffer tube containing at least one optical fiber is disclosed. The filler rod comprises an elongated rod extruded from a polypropylene homopolymer, a polypropylene-polyethylene copolymer (i-PP) resin material, or preferably, from a polypropylene-polyethylene copolymer having a nucleating agent disbursed therein. The resin material is foamed during extrusion so as to have a plurality of void spaces therein and a relative density which is less than 1 relative to the unfoamed resin material. As compared to rods made from high density polyethylene, the i-PP filler rods show a greater foaming efficiency, more efficient use of material, an improved combination of mechanical properties and density, reduced post-extrusion shrinkage and a substantial reduction in the sticking of the filler rods to the outer jacket that is experienced with high density polyethylene filler rods.
