Mining and Petrochemical Tray-Rated, Loose Tube, Gel-Free Cable

Corning dielectric, tray-rated, mining, and petrochemical fiber optic cables are designed for indoor and outdoor use in mining and petrochemical backbones (aerial and duct) as well as horizontal intrabuilding and tunnel backbones with limited-smoke and zero-halogen requirements. The Corning-pioneered loose tube cable construction places fibers in buffer tubes to provide stable and reliable transmission parameters for a variety of voice, data, video, and imaging applications. The SZ-stranded, loose tube design isolates fibers from installation and environmental rigors and allows easy mid-span access. The design also delivers high-fiber density given its small diameter, allowing flexibility to suit many system designs.

The cable’s innovative waterblocking technology eliminates the need for a traditional flooding compound for more efficient and craft-friendly cable preparation. The specially formulated black jacket is UV-resistant and has a flame-retardant LSZH™ inner and outer layer. These double jackets resist hazards found in mines and petrochemical complexes, making this cable ideal for any harsh environment requiring a more robust cable and suitable for direct-buried applications. All-dielectric construction offers more tensile strength and eliminates grounding concerns. With extended storage and operating temperature range of -58° to 167°F (-50° to +75°C), the cable is listed OFN-LS and CSA FT4-ST 1 for up to 288 fibers and cable tray-rated per CSA C22.2 No. 230 and No. 232.
