| KT3003 GYTA Outdoor Fiber Optic Cable |
| Description&Standards : |
The fibers, 250μm,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, sometimes sheathed
with polyethylene (PE) for cable with high fiber count, locates
in the center of core as a metallic strength member.
Tubes (and fillers) are stranded around the strength member
into a compact and circular cable core.An Aluminum Polyethylene
Laminate (APL) is applied around the cable core,which is filled
with the filling compound to protect it from water ingress.
Then, the cable is completed with a PE sheath.
|
GYTA cable complies with Standard YD/T 901-2001
as well as IEC 60794-1. |
| Characteristics: |
| Good mechanical and temperature performance; |
| High strength loose tube that is hydrolysis resistant; |
| Special tube filling compound ensure a critical protection of fiber; |
Specially designed compact structure is good at preventing loose
tubes from shrinking; |
| PE sheath protects cable from ultraviolet radiation; |
| The following measures are taken to ensure the cable watertight: |
| (1)Steel wire used as the central strength member; |
| (2)Loose tube filling compound; |
| (3)100% cable core filling; |
| (4)APL moisture barrier. |
