Corning Cable Systems ALTOS® All -Dielectric Gel -Free Cables are designed for outdoor and limited indoor use for campus backbones in lashed aerial and duct installa-tions. The loose tube gel -free design is fully waterblocked using craft -friendly, water -swellable materials, which means cable access is simple and no clean up is re-quired. The flexible craft -friendly buffer tubes are easy to route in closures and the SZ -stranded, loose tube design isolates fibers from installation and environmental rigors while allowing easy midspan access. The all -dielectric cable construction requires no bonding or grounding and these cables have a medium -density polyethylene jacket that is rugged, durable and easy to strip.
