Corning 012ESF-T4101DA1 — Loose Tube, Indoor/Outdoor, Riser, 12 Fiber, 8.3/125, 0.4/0.3 dB/km, PVC Jacket, SMF-28e, Aluminum Interlocking Armor, FREEDM/LST, 1 Tube

Corning 012ESF-T4101DA1 — Loose Tube, Indoor/Outdoor, Riser, 12 Fiber, 8.3/125, 0.4/0.3 dB/km, PVC Jacket, SMF-28e, Aluminum Interlocking Armor, FREEDM/LST, 1 Tube

The Corning 012ESF-T4101DA1 cable is a 12-fiber loose tube single-mode (OS2) design with aluminum interlocking armor for robust indoor/outdoor use. It is Riser (OFCR) rated, making it suitable for aerial, duct, direct buried, horizontal, and riser installations. The cable’s construction includes water-swellable dielectric strength members, a UV-resistant flame-retardant jacket, and one active tube containing 12 color-coded fibers. It delivers excellent optical performance with a maximum attenuation of 0.4 dB/km at 1310 and 1383 nm, and 0.3 dB/km at 1550 nm, compliant with ITU-T G.652.D standards. With strong tensile strength, wide temperature tolerance, and corrosion-resistant armor, this cable is built for reliability in challenging environments.
