Corning FREEDM 12-Fiber OM3 LSZH 0.9mm Indoor/Outdoor Tight-Buffered Cable (012T8X-32188E2G)

The Corning FREEDM™ 012T8X-32188E2G is a 12-fiber OM3 multimode ClearCurve® optical fiber cable designed for indoor and outdoor installations. Featuring a TB3 tight-buffered construction with 900 µm buffered fibers, it facilitates easier cable preparation and termination for low-fiber-count LAN applications. Its all-dielectric construction, waterblocking technology, and flame-retardant LSZH/FRNC outer jacket make it suitable for interbuilding and intrabuilding backbone networks, including duct, conduit, riser, horizontal, and direct-buried installations.
