Figure 8 Aerial Fiber Optics Cable
Application
Primarily for carrier-class fixed line, mobile communications networks, CATV fiber-optic backbone network, used for the core and aggregation network and access network for base stations connected. Figure 8 Aerial Self Support cables are designed suitably for Outdoor UV/harsh outdoor environment protection between buildings short, medium span aerial installations.
Construction
Figure 8 Aerial Fiber Optics Cable
1Self-support wire with oversheath
2Outer sheath
3Ripcord & water blocking element
4Peripheral strength element-Aramid yarn
5Peripheral strength element-Aramid yarn
6Loose tube
7Colour fibers
8Center strength member(CSM)- Galvanized steel wire with oversheath
Property
- CSM: Galvanized steel wire with oversheath could provide efficient tension for cable.
- Loose Tube: 6 or 12 fibers per PBT loose tube and filled with a suitable jelly compound.
- Filler:Thermoplastic rods, where needed.
- Stranding:Loose tubes (and filler), SZ stranded around the CSM.
- Stranding:Loose tubes (and filler), SZ stranded around the CSM.
- Longitudinal water tightness : The core is water blocking by using petroleum jelly.
- Peripheral Strength Element: Aramid yarns.
- Inner Sheath: Only for double sheath. (Option)
- Water Blocking Element:Only for double sheath, between inner sheath and out sheath .(Option)
- Ripcord:Nylon thread or Aramid yarn for easily stripping of the sheath.
- Outer Sheath: (Option)
LAP sheath: Laminated Aluminum sheath for moisture barrier.
