Fiber type:G.657A1
Futong's bending loss insensitive single mode fiber (G.657 A1 fiber) is made by the advanced Complete Chemical Synthesis method, which could keep the content of OH- in a very low level in the perform. So the fiber has an outstanding attenuation coefficient, low water-peak and a good transmission performance. It is fully compatible with the G.652D network, with small bending radius. So it can completely meet the requirements of FTTH wire arrangement.
