Telecommunications cable reinforcements
Advantex reinforcements with Aquablock coating technology for telecommunications cable prevent water from damaging optical fibers. During cable jacketing, the reinforcement carrying the absorbent powder is wrapped around the cable core of optical fibers. If water gets into the cable, the coating swells in 1 minute to its maximum-absorption level--three times its weight in water--and seals off the damaged area.
