Corning stranded loose tube cables are designed for out-
door use for campus, city and intercity backbones in duct
installations.
The loose-tube cable construction, by isolating the fibers
from installations and environmental rigors, provides
stable and highly reliable transmission parameters. The
buffer tubes and fibers in each tube are color-coded for
quick and easy identification.
The SZ-stranded construction further reduces installation
and environmental influences on the transmission param-
eters and allows mid-span access.
These cables are designed for installation in conduits,
ducts and on cable racks.
Features and Benefits
All-dielectric cable construction
Requires no grounding or bonding
UV and microbe resistant
Can be installed in ducts or conduits
Waterblocking technology
OSP (outdoor) applications
Fibres/buffer tubes colour coding to Telcordia-
Bellcore
Easy identification of the individual tubes and fibres
Dry cable core by means of water swellable elements
Allows efficient and craft-friendly cable preparation in
outdoor or indoor/outdoor applications
