Product Characteristics
Fiber type：G.657A2
Futong's bending loss insensitive single mode fiber (G.657 A2 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 a outstanding attenuation coefficient, low water-peak and a good transmission performance. It can transmit in O-E-S-C-L for the whole band, and fully compatible with the G.652D network, under the premise of small bending diameter of wire arrangement places. At the same time, the high quality coating material make it a higher fatigue strength, which can prevent it from broken when the cable is in a small bending radius at long-terms .So it can completely meets the requirements of FTTH wire arrangement.
Spec No.：FT-SPEC-OF-G.657A2-20220111
