- Description
The Corning SST 12-Fiber OM4 Dielectric Armour Indoor/Outdoor Central Tube Cable is designed for reliable optical transmission in indoor and outdoor installations. Featuring 12 × 50/125 µm OM4 multimode fibers in a compact central tube construction, it provides stable transmission performance while protecting the fibers from installation stresses and environmental conditions.
Its all-dielectric construction eliminates the need for grounding or bonding. Laminated swelling glass yarn armour provides improved rodent resistance and longitudinal water protection, while the flame-retardant LSZH/FRNC outer jacket offers low-smoke, zero-halogen and non-corrosive properties. The cable is suitable for installation in ducts, conduits, vertical risers and general-purpose horizontal applications.
