Indoor Fiber Optics Cable (BO Type)
Application
Multi-core breakout indoor Optic cable is applied to branch cable in building access and interconnection of fiber optic equipments. It has good mechanical and environmental characteristics. Flame retardant characteristics complies the requirements of relevant standards. Soft, flexible and easy to do stripping, splicing and cabling.
Construction
Indoor Fiber Optics Cable (Multi-Core Breakout type)
1FRP rod
2Cable subunit
3Peripheral strength element-Aramid yarn
4Low smoke zero halogen (LSZH) flame retardant PE
Property
- Available in single mode fiber and multi-mode fiber.
- CSM: Glass fiber reinforced plastic rod(FRP)with oversheathing could provide efficient tension for cable.
- Cable subunit: Tight buffer fibers、Aromatic yarn and PVC sheath.
- Stranding: Cable subunit would be stranded around the CSM.
- Peripheral Strength Element: Aramid yarn is used.
- Ripcord:Nylon thread or Aramid yarn for easily stripping of the sheath
- LSZH PE sheath: Low Smoke Zero Halogen sheath for Flame retardant characteristics.
