G-Series Subgrouping Plenum Rated Cables


  • Used in trunking, LAN and distribution applications where versatile installation capability is required for ducts, plenums, and air-handling spaces
  • Design allows subcables to be routed to multiple locations such as wiring racks and closets
  • Suitable for both indoor plenum and outdoor installation - no need to splice outdoor cable to indoor cable at the building entrance

Cost Savings:

  • 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
  • No need to splice outdoor cable to indoor cable at building entrance
  • High crush resistance may eliminate the need for innerduct


  • High performance components and construction
  • UL Listed in accordance with NEC sections 770.179(a) for use in ducts, plenums and air-handling spaces
  • Cable materials are indoor/outdoor - UV, water and fungus resistant
  • Wide operating temperature range of -40°C to +85°C
  • Helically stranded core for greater flexibility and mechanical protection of the optical fibers
  • Multifiber color-coded subcables, each similar to the D-Series Distribution cable, are easy to identify for improved cable management during installation
  • Best design for multimode and single-mode fiber hybrid cables
  • Available with 6-fiber (4.5mm) or 12-fiber (5.5mm) subcables
  • Jacket highly chemical resistant for installation in harsh industrial environments
  • Interlocking armor can be applied to cable as an alternative to conduit installation
