ABSTRACT:
The specification describes optical fiber cables designed for microduct installations. The microduct cables are coated with a sheath having particulates added to modify the drag of the outer surface of the cable to air, and thereby facilitate air blown installation. The particulates are nanoclay, silica, alumina, or other suitable solid particles of less than 5 microns. The coating comprises a prepolymer containing the filler, and is UV cured.
