Abstract The specification describes a water blocking tape for an optical fiber cable wherein the optical fibers in the cable are wrapped with a synthetic fibrous non-woven tape coated with a superabsorbent polymer powder coating. The particles in the powder are ultra-fine, i.e. have less than 10% weight fraction over 250 microns in diameter, and less than 2% weight fraction over 300 microns in diameter. Controlling the particle size within this small range is found to reduce microbending losses in the optical fiber.
