G657A2 Fiber Specification

Short Description:

Hunan Jiahome’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 G657A2 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.

G657A2 Fibre Optic Cable Are Used to:

All types of fibre cables with different structures
High-performance optical network operating in O-E-S-C-L band
High-speed optical routes for FTTH networks
Cables with extreme low bending requirements
Small-sized fibre cable and optical component
