Specification model: bending-insensitive single-mode fiber (G.657A2)
Executive standard: Meet the requirements of ITU-T G.657.A1/A2/B2 optical fiber technical specifications.
Product features:
- The minimum bending radius can reach 7.5mm, with excellent bending resistance;
- Fully compatible with G.652 single-mode fiber;
- 1260～1626nm full waveband transmission;
- Low polarization mode dispersion meets the needs of high-speed and long-distance transmission;
- Used in various optical cables, including ribbon optical cables, with extremely low additional attenuation of micro-bending;
- It has high anti-fatigue parameters to ensure the service life under small bending radius.
- Application Note: It is applied to optical cables of various structures, full-wavelength transmission at 1260~1626nm, FTTH high-speed optical routing, optical cables with small bending radius requirements, small-sized optical cables and optical fiber devices, and the requirements of using L-band.
