Product Description

AOF Bend-insensitive Single-mode Fiber
It encompasses all the features of Non-Dispersion Shift Single-mode Fiber and even does better in the aspect of bending property, particularly adapt the transmission system across the entire 1260nm to 1625nm wavelength spectrum. The AOF Fiber performs low bending additional loss in the long wavelength region. Even in the 1625nm wavelength window, the fibers only have a low additional loss equals to 0.8dB with a bending radius being 7.5mm.The Fiber can be used in all cable constructions, especially tight buffered cable which is the key of Fiber-To-The-Home and Fiber-To-The-Mansion
Features
The fiber complies with or exceeds the ITU-T Recommendation G.652.D and G.657.A1, the IEC International Standard 60793-2-50 type B.1.3 Optical Fiber Specification.
The fiber is manufactured using the advanced VAD process. Because of the advantages of the process, AOF fiber shows extremely refined refractive index profile control, excellent geometrical performance, low attenuation, etc.

1. Designed for operation over the 1260nm to 1625nm wavelength spectrum, completely low attenuation in the 1383 nm region;
2. Excellent bending property adapting special occasions which require bending radius;
3. Being compatible with existing G.652D Fiber;
4. Accurate geometrical parameters that insure low splicing loss and high splicing efficiency;
5. Excellent PMD factor supporting high-speed and distance upgrades.
