Corning 12 Strand 50/125 Multimode OM3 Indoor/Outdoor LT Riser Fiber Optic Cable - Black (Per Foot)

Reference#: 69113
Item#: COR-012TSF-T4180D20


Corning Cable Systems FREEDM LST Cables are flame-retardant, indoor/outdoor, riser-rated cables designed for interbuilding and intrabuilding backbones in aerial, duct and riser applications. With a riser rating, there is no need for a transition splice when entering the building. Available in a compact design in fiber counts from 2 to 24 fibers, these cables are 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, allows easier cable access and simplifies the use of buffer tube fan-out kits.

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.


  • Riser rating eliminates need for transition splices when entering buildings
  • Gel-free waterblocking technology allows craft-friendly cable preparation 
  • Color-coded tubes and fibers provide quick and easy identification
