Indoor Fiber Optics Cable (BD Type)


Applied to in-building backbone. PEWC indoor distribution bundle type optical cables offer maximum 96 fibers count with single or multi cable subunit of 900 μm tight-buffered fibers which are color coded for easy identification. Cables provide flame retardant characteristics and flexible thermoplastic jacket provides excellent handling characteristics. Full dielectric construction, no grounding required.


Indoor Fiber Optics Cable (Distribution Bundle type)

1Low smoke zero halogen (LSZH) flame retardant PE
26/12 Cable subunits
3Tight-buffered fibers
4FRP rod


  • Available in single mode fiber and multi-mode fiber.
  • CSM: Glass fiber reinforced plastic rod(FRP) with oversheathing could provide efficient tension for cable.
  • 6/12 Cable subunits: Tight buffer fibers、Aromatic yarn and coloured flame retardant PE sheath
  • Stranding: Cable subunits would be stranded around the CSM.
  • Peripheral Strength Element: Aramid yarns is used.
  • Ripcord:Nylon thread or Aramid yarn for easily stripping of the sheath.
  • LSZH PE sheath: Low Smoke Zero Halogen sheath with Flame retardant characteristics.
