Product Characteristics
Fiber type：G.657A1 (Compatible G.652D)
B1.3/B6a1 standard recommended by IEC. Low attenuation and dispersion and bending insensitive, compatible with G.652.D and G.657.A1 optical fiber, fits the operation over the full optical spectrum from 1280nm to 1625nm by suppressing hydroxyl (OH-) absorption near 1383 nm below 0.33dB/km.
