Fiber Optics Cables

 

Type of Fiber Optics Cables

 

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.
 

Slotted Ribbon Type Fiber Optics Cable

1. LAP sheath
2. Water blocking tape
3. Ripcord
4. 4-fiber ribbon
5. Slotted core
6. Center strength member(CSM)

 

CSM: Could provide efficient tension for cable.(Option)
 
  Galvanized steel wire
  FRP Rod (Non-metallic type for power line system)
PE Slotred Core: HD polyethylene extrusion.
Stranding: Accommodate the 4-fiber ribbons into grooves of slotted core.
Longitudinal Water Tightness: Water blocking tape be used, totally dry core enhance operation for splicing.
Ripcord: Aramid yarn thread for easily stripping of the sheath.
Outer sheath: (Option)
 
  LAP sheath: Laminated Aluminum sheath for moisture barrier
  Black polyethylene sheath
