HC Series High-Density Riser Rated Cables


  • Designed for installation in an underground duct for data transmission between nodes or hubs
  • Cable can also be routed vertically inside buildings


  • Rugged tight-buffered fiber unit construction
  • Cable materials are indoor/outdoor: UV, fungus, and water resistant
  • The high-density breakout cables offer a >20% reduction in diameter and a >20% reduction in weight relative to conventional loose-tube cables, allowing for greater fiber density and cable packing within a duct
  • UL listed in accordance with NEC 770.179(b) for use in vertical runs in building risers or from floor to floor
  • Core-Locked™ outer jacket design for installation survivability
  • Helically stranded core for greater flexibility and mechanical protection of the optical fibers
  • Cable offers a cost savings by eliminating the need to splice outdoor cable at building entrance
  • Cable can be terminated with 900µm fanout kit for LC connectorization
  • Construction options available for direct termination of tight-buffered fiber units to MPO/MTP connectors
  • Suitable for direct pulling with wire mesh grips
