🌐 Corning A-DF(ZN)2Y(ZN)2Y 2×12 E9/125 Outdoor Optical Cable

Description:
The Corning A-DF(ZN)2Y(ZN)2Y cable features 24 single-mode fibers (E9/125) arranged in 2 tubes. Designed for direct burial, conduit, or duct installations, it offers outstanding mechanical strength and long-term reliability thanks to its dual-layer HDPE/LLDPE sheath. The all-dielectric construction makes it safe for installation near electrical infrastructure.
