Reference#: 69083
Item#: COR-012ESF-T4101D20


Corning Cable Systems FREEDM® LST™ Gel -Free Cables are flame -retardant, indoor/outdoor, riser -rated cables designed for interbuilding and intrabuilding back-bones in aerial, duct and riser applications. With a riser rating, there is no need for a transition splice when enter-ing the building. Available in a compact design, these cables are protected against water penetration by inno-vative waterblocking tapes and yarns that swell to absorb water. Waterblocking without the use of messy gels pro-vides more efficient and craft -friendly cable preparation, allows easier cable access and simplifies the use of buf-fer 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 midspan 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.
