Corning 048TUZ-T4180D20 — 48-F OM3 LSZH Indoor/Outdoor 3.0/1.0 dB/km 850/1300nm ALTOS

Corning 048TUZ-T4180D20 — 48-F OM3 LSZH Indoor/Outdoor 3.0/1.0 dB/km 850/1300nm ALTOS

The cable offers high-performance multimode connectivity with 50 µm OM3 fibers, designed for both aerial and direct-buried installations as well as indoor general-purpose horizontal runs. Featuring a flame-retardant, low-smoke zero-halogen (LSZH) jacket, it meets stringent NEC, IEC, and IEEE safety standards for riser-rated and direct burial use. The cable has a robust loose tube design with four active buffer tubes, each holding 12 color-coded fibers, protected by multiple water-swellable and flame-retardant layers for durability in harsh environments. It supports 3.0 dB/km attenuation at 850 nm and 1.0 dB/km at 1300 nm, ensuring excellent performance for Gigabit and 10 Gigabit Ethernet over extended distances. With a compact 12.8 mm outer diameter and a high tensile strength rating, it’s an ideal choice for high-density, long-life fiber network deployments.
