Overviews
Outdoor Figure 8 Flat Drop cable is a cable designed specifically for FTTH project. It adopts double reinforcement figure 8 structure, the optical fiber unit is positioned in the center, two parallel fiber reinforced steel wire are placed at two sides, then the cable is completed with a black or white color LSZH Sheath. This drop cable can directly drop into the building household from the fiber optic splice closure.
Key Features
Suitable for limited space field of the branch, indoor series;
Laid to facilitate construction operations;
Jacket use low smoke, halogen-free flame-retardant materials;
Prevent lightning and strong electric environment;
FRP strengthen the component materials.
Standards
Unless otherwise specified in this specification, all requirements shall be mainly in accordance with the following
standard specifications.
Optical fiber …ITU-T G.652D、G657、IEC 60793-2-50
Optical cable …EN 60811、EN 60794-1-2
