2 / 4 / 6 / 8 / 12 / 16 / 24 CORE SINGLE MODE OUTDOOR ARMOURED
GYXTW G657A FIBER OPTICAL CABLE
Product Description:
The structure of GYTS is to sheath 250um optical fiber into a loose
tube made of high modulus material, and the loose tube is filled
with waterproof compound. The center of the cable core is a metal
reinforced core. For some fiber optic cables, a layer of
polyethylene needs to be squeezed outside the metal reinforced
core. The loose tube and the filling rope are twisted around the
central reinforcing core to form a compact and circular cable core,
and the gaps in the cable core are filled with water blocking
fillers.
The 250μm fiber is positioned in a loose tube made of a high
modulus plastic. The tubes are filled with a water-resistant
filling compound. The tube is wrapped with a layer of PSP
longitudinally. Between the PSP and the loose tube water-blocking
material is applied to keep the cable compact and watertight. Two
parallel steel wires are placed at the two sides of the steel tape.
The parallel steel wires are placed at the two sides tape. The
cable is completed with a polyethylene (PE) sheath.
Features:
- Good mechanical and temperature performance
- High strength loose tube that is hydrolysis resistant
- Special tube filling compound ensure a critical protection of fiber
- Crush resistance and flexibility
- PSP enhancing moisture-proof
- Two parallel steel wires ensure tensile strength
- Small diameter, light weight and friendly installation
- Storage / Operating Temperature: -40℃~+70℃
