| KT3007 GYTS 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
illing 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.
The PSP is longitudinally applied over the cable core, which is
filled with the filling compound to protect it from water ingress.
The cable is completed with a PE sheath. |
GYTS 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 fiber; |
Specially designed compact structure is good at preventing
loose tubes from shrinking; |
| Crush resistance and flexibility; |
| 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)PSP enhancing moisture-proof. |
