Fiber Optics Cables

 

Type of Fiber Optics Cables

 

The cable are intended for operation under conditions normally encountered in the last portion of all-optical networks. Designed to run from the Network Access Point (NAP) to the subscriber premises. Available from 1 to 12 fiber counts,LSZH (Low Smoke Zero Halogen),flame retardant and costomizable to any requested specifications.
 

For Underground Conduit Installation

1. Outer sheath   
2. Ripcord
3. Water blocking & Peripheral Strength Elements: aramid yarns.
4. Central loose tube
5. Colored fibers

 

For Aerial/Self-supporting Installation

1. Self-support wire with oversheath
2. Outer sheath
3. Water blocking element
4. Ripcord
5. Inner sheath
6. Ripcord & water blocking element
7. Peripheral Strength Elements: aramid yarns
8. Central loose tube
9. Colored fibers

 

 

Central Loose Tube: thermoplastic material (PBT), containing optical fibers and filled with a suitable water tightness jelly compound.
Peripheral Strength Elements: aramid yarns.
Longitudinal water tightness : Water blocking element used for eliminates the need for traditional flooding compound and provides efficient and craft-friendly cable preparation.
Ripcord:Nylon thread or Aramid yarn for easily stripping of the sheath.
Outer Sheath: (Option)
 
  Polyethylene sheath
  LSZH polyethylene sheath: Low Smoke Zero Halogen sheath for Flame retardant characteristics.
