Improved optical fiber cable coatings

摘要

Dual coated optical fiber cables are optimized for air blown installation. The elastic properties of both coatings are controlled within a desired range over the full range of potential installation temperatures, e.g. 0-45° C. The material of the inner coating has a T_g below -15° C., and preferably below -25° C., and the material of the outer coating has a T_g above 60° C., and preferably above 75° C.
