Eliminates the need for traditional flooding compound
and provides efficient and craft-friendly cable preparation
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

low-temperature cables are designed for
extreme cold temperature environments with an ex-
tended operating range of -50° to +70°C (-58° to
+158°F). DIelectric and armored jackets allow for duct,
direct-bured or aerial (lashed) installations. See specifica-
tion section for application selection.
