Corning 144 Strand Singlemode Indoor/Outdoor LT Riser Fiber Optic Cable - Black (Per Foot)

Reference#: 69161
Item#: COR-144EUF-T4101D20


Corning Cable Systems FREEDM® Loose Tube Gel-Free Riser Cables are flame-retardant, indoor/outdoor, riser-rated cables designed for inter-building and intra-building backbones in aerial, duct and riser applications. Their 144-fiber singlemode LT riser cable is the solution for large college campuses, industrial parks, multi-building offices and other places that need high-speed networking over long distances. As an indoor/outdoor fiber optic cable, it is certified to meet both the environmental protection requirements of the outdoors and the first safety standards of indoor equipment. You won’t need a transitional splice when routing cables into buildings, saving you labor expenses and eliminating a potential “weak spot” in your network.

This Corning 144-strand indoor/outdoor rated fiber is protected against water penetration by innovative water-blocking materials that swell to absorb water. Water-blocking without the use of messy gels provides more efficient and craft-friendly cable preparation. It also makes cable access easier and simplifies the use of buffer tube fan-out kits. The buffer tubes and fibers in each tube are color-coded for quick, easy identification. The SZ-stranded, loose tube design isolates fibers from installation and environmental rigors and allows for easy mid-span access.
The cable design is also National Electrical Code® (NEC®) listed (OFNR and FT-4). The all-dielectric cable construction requires no grounding or bonding, and the UV-resistant, flame-retardant jacket is rugged, durable and easy to strip.

Use Corning 144-Strand Singlemode Indoor/Outdoor LT Riser Cable if you are installing a large high-speed network that requires inter-building or intra-building runs along walls, up poles or through underground ducts.
