Type of Fiber Optics Cables

 

LSZH cables are designed for indoor and outdoor use. Dry core design for excellent water blocking performance and easier handling. The outer jacket uses a flame-retardant Low Smoke Zero-Halogen material. Applied to connection between outside plant stranded loose tube cable and terminal distribution frame in central office.

Loose Tube Flame Retardant Cable

1. Outer sheath    
2. Ripcord 
3. Peripheral strength element-Aramid yarn
4. Water blocking element
5. Loose tube
6. Colour fibers 
7. Center strength member(CSM)- Galvanized steel wire with oversheath

 

CSM: Galvanized steel wire with oversheath and wrappng of water blocking element, 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.
Peripheral Strength Element: (Option)
 
  Aramid yarns could be used if required.
  Non-strength element.
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)
 
  LSZH LAP sheath: Low Smoke Zero Halogen Laminated Aluminum sheath for moisture barrier. and Flame retardant characteristics.
  LSZH PE sheath: Low Smoke Zero Halogen sheath for Flame retardant characteristics.
