Results in economical use of duct space and facilitates
installation
Two jacket layers and two steel tape armor layers
Provide superior rodent resistance for direct-buried ap-
plications
Innovative waterblocking technology
Eliminates the need for traditional flooding compound
and provides efficient and craft-friendly cable preparation
Medium-density polyethylene jacket
Rugged, durable and easy to strip (while providing supe-
rior protection against UV radiation, fungus, abrasion and
other environmental factors)
Corning ALTOS

RD double-jacket, single-armored ca-
bles are rugged armored cables with a reduced diameter
designed for direct-buried, duct and aerial (lashed) in-
stallation. The loose tube design provides stable perfor-
mance over a wide temperature range and is compatible
with any telecommunications-grade optical fiber.
