D-Series Distribution Plenum Rated Cables


  • Used in trunking, LAN and distribution applications where small size, lightweight, and versatile installation capability are required for ducts, plenums, and air handling spaces
  • Ideal configuration for a single termination point requiring multiple fibers


  • High performance components and construction
  • High specific strength-to-weight ratio and compact cable design for limited conduit space and tight bends in long cable pulls
  • Helically stranded core for flexibility, survival in difficult installations, and mechanical protection for the fibers
  • Lower installed cost
  • High performance tight-buffered coating on each fiber for environmental and mechanical protection
  • High crush resistance may eliminate the need for innerduct
  • 900 µm buffer eliminates the need for costly and time-consuming installation of fanout kits or pigtail splices because connectors terminate directly to the fiber.
  • UL Listed in accordance with NEC section 770.179(a) for use in ducts, plenums and air-handling spaces

Indoor ("S" Jacket)

  • Indoor-only flexible flame retardant plenum jacketed cables available
  • 2 to 24 fibers
  • Can have interlocking armor applied to cables as an alternative to conduit installation

Indoor/Outdoor ("K" Jacket)

  • Indoor/Outdoor plenum cables eliminate the need for costly cable transitions in different installation environments
  • Cable materials are UV, water and fungus resistant
  • Higher fiber counts available than similar cables available by others in subgrouped configuration
  • Jacket is highly chemical resistant for installation in harsh industrial environments
  • Interlocking armor can be applied to cables as an alternative to conduit installation
  • Can be installed outside and in plenum or riser pathways inside, eliminating the need to transition cable types between environments
  • 2 to 72 fiber configuration is smaller and lighter than comparable sub-grouped cables, which is ideal for installation in areas with limited space or tight bends
