Self Supporting Aerial Fiber Optic cables GYTC8A

Product Description

The fibers,250um, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire locates in the center of core as a metallic strength member. The tubes are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture battier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to figure 8 structure. Also figure 8 cable GYTC8Y, GYTC8S are also available on request. This type of cable is specially applied for self-supporting aerial installation.

Product Characteriistics

1.High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cast
2.High strength loose tube that is hydrolysis resistant
3.Special tube filling compound ensure a critical protection of fiber
4.The following measures are taken to ensure the cable watertight:
5.Steel wire used as the cen tral strength member
6.Loose tube filling compound
7.100% cable core filling



Features:
Excellent mechanical and environmental performance
Good waterproof performance
Gel-filled Loose tube protect the fiber well


Standars:
The products comply with relevant standards of YD/T,IEC and ITU.
