Three jacket layers and two steel tape armor layers
Provide superior rodent resistance for direct-buried ap-
plications
Flexible, craft-friendly buffer tubes
Facilitate easy routing in closures
Totally gel-free cable design with innovative water-
blocking technology
Makes fiber access simple and clean
Medium-density polyethylene jacket
Makes cable rugged and durable while being flexible and
easy to strip
Corning ALTOS
®
gel-free triple-jacket, double-armored
cables are rugged, armored cables designed for di-
rect-buried installations. The loose tube design provides
stable performance over a wide temperature range and
is compatible with any telecommunications-grade optical
fiber.
