GYFTY Di-Electric Armoured Stranded Loose Tube Cable Fiber Optic Cable

Product Description

Name: GYFTY Fiber Optical Cable 

In the GYFTY cable, single-mode/multimode fibres are positioned in the loose tubes, which are made of high modulus plastic materials, while the loose tubes strand together around non-metallic central strength member (FRP) into a compact and circular cable core. For certain high fibre count cables, the strength member would be covered with polyethylene (PE). The water-blocking materials are distributed into the interstices of the cable core.Then the cable is completed with a PE sheath.

Class A Core Fiber:

 

       *Wonderful Flexiblity 

     **Speedy and Stable

    ***Long transmission Distance

Non-metallic strength  member FRP:

 

       *Anti-corrosion ,high-level strength

      **Central strength member enhances

 the compressive property of cable and

protects fiber

Outer sheath :

 

          *All-new PE materials 

        **Smooth surface 

      ***Anti-corrosion 

    ****Environmental Friendly

 

Sufficient Quantity:

 

 *Sufficient quantity is our promise .
**Meter measurement is printed clearly very roll.

Advantages:
1. Low dispersion and attenuation.
2. Proper design, precise control for fiber excess length and distinct stranding process render the cable excellent mechanical and
environmental characteristics.
3. Anti-electromagnetism ability.
4. Small cable diameter, light cable weight, easily to install.
