B-Series Breakout LSZH OFNR-LS and IEC Rated Cables


  • Low-smoke and zero-halogen cable suitable for indoor and outdoor applications requiring an extremely rugged cable where maximum mechanical and environmental protection are necessary
  • Easiest cable to install where direct termination of the subcable to a connector and a direct run to panels and equipment are desired


  • Zero-halogen construction meets IEC 60754-2
  • Meets low-smoke requirements of IEC 61034-2 and UL 1685 OFNR-LS
  • Flame-retardant to the requirements of IEC 60332-3-24 and UL 1666 OFNR
  • Suitable for indoor or outdoor applications
  • Jacket is UV, fungus and moisture resistant
  • Round cable construction for easy handling and termination
  • Breakout style cable with 2 to 24 fibers
  • 2.0mm and 2.5mm subcables (2.9mm also available)
  • Suitable for indoor/outdoor confined spaces including:
    • Building risers
    • Cable trays
    • Central offices
    • Mass-transit rail systems
