G-Series Subgrouping Riser Rated Cables


  • Indoor/outdoor tight-buffered design allows cables to be installed in intra-building backbone and inter-building campus locations without costly transitions between cable types
  • Design allows multifiber subcables to be routed to multiple locations such as wiring racks and closets

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(b) for use in vertical runs in building riser shafts or from floor to floor
  • 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
  • Core-Locked™ outer jacket surrounds the subcables for excellent crush resistance, survivability and use in long vertical installations
  • Multifiber color-coded subcables, each similar to the D-Series Distribution cable, are easy to identify for improved cable management during installation
  • Subcabling cable design permits mid-span access
  • Best design for multimode and single-mode fiber hybrid cables
  • Ideal for direct pulling with wire mesh grips
  • Available with 6-fiber (4.5mm) or 12-fiber (5.5mm) subgroups
  • Interlocking armor can be applied to cables as an alternative to conduit installation
