Outdoor Steel Wire 1 2 4 6 Core G657a1 FTTH Drop Cable
Outdoor self-supporting steel wire 1 2 4 6 core g657a1 ftth drop cable
Description of Outdoor self-supporting steel wire 1 2 4 6 core g657a1 ftth drop cable
FTTH fiber optic cable is Fiber to Home, which used for linking the equipment and components in the fiber optic network. The fibers is between two parallel FRP / steel wire. Then it is self-supported by diameter 1.0mm steel wire. Finally this cable is completed with black or white LSZH sheath.
Features of Outdoor self-supporting steel wire 1 2 4 6 core g657a1 ftth drop cable
1, High tensile of the diameter1.0mm steel wire meet the requirement of self-supporting and reducing the installation cost.
2, Two parallel FRP/ steel wire strength members ensure good performance of crush resistance to protect the fiber
3, Novel flute design, easily strip and splice, simplify the installation and maintenance
4, Low smoke zero halogen and flame retardant sheath
5, Single mode
6, (2.0±0.2)x(5.0±0.2)mm
7, Compliant with Telcordia GR-326-CORE specification
