At present, in most of FTTH project, FRP and KFRP are widely used because of their advantages over steel wire and glass fiber. From outer appearance, FRP is white, KFRP is golden, and its performance is different. Below Yingda Photonic make a brief introduction of KFRP, for reference only:
Features
Not sensitive to the lightning strike, applied to the areas which are common with frequent lightning and rain;
Not obstructed by induced current and can be installed close to the power unit and device;
No harmful gas that would affect the optical transmission indicators;
Has the characteristics of high tensile and light weight;
bullet-proof, ant-proof and anti-tooth proof.

Product length
Diameter（0.40～3.00）Standard Length for delivery≥25km
Diameter（3.20～5.00）Standard Length for delivery≤12.5km
For nonstandard diameter and length, we could produce it as clients’ requirements.
