Provides rodent resistance for direct-buried applications
Flexible, craft-friendly buffer tubes
Facilitate easy routing in closures
SZ-stranded, loose tube design
Isolates fibers from installation and environmental rigors
and facilitates mid-span access
Dielectric central strength member
No preferential bend and requires no bonding or ground-
ing
Medium-density polyethylene jacket
Makes cable rugged and durable while being flexible and
easy to strip
ALTOS
®
gel-free, double-jacket, single-armored cables
are rugged, armored cables designed for direct-buried
installation while suitable for duct and aerial (lashed)
installation. The loose tube design provides stable perfor-
mance over a wide temperature range and is compatible
with any telecommunications-grade optical fiber.
