摘要

^7fInstallation of low fiber count units in microducts is an ideal method for deployment of fiber-to-the-subscriber networks in urban areas. Once microduct systems are constructed, fiber units can be installed by blowing installation as needed. Units with 2-12 fibers can be installed in microducts to provide connectivity directly to office buildings, businesses, and homes. In order to achieve maximum installation efficiency, it must be possible to blow these units long distances at high speeds. Ideal units must therefore have a balance of stiffness, flexibility, and low surface friction, in addition to excellent optical performance. The properties of the materials used in construction of these units are critical to their performance. This paper will present the development of optimized mineral-filled thermoplastic materials for use in blown fiber units. Addition of mineral fillers to traditional thermoplastics improves mechanical properties and reduces thermal expansion. Since the fillers act to limit shrinkage and thermal expansion/contraction, blown fiber units constructed using these resins have excellent optical performance throughout the typical service temperature window for outside plant fiber optic cable. Compared to blown fiber units constructed from traditional thermoplastics, units constructed using filled thermoplastics have increased stiffness, increased surface roughness and reduced surface friction. These improvements in mechanical and surface properties translate into outstanding performance in blowing installation.
