YOFC FullBand® Plus Low Loss Single-mode Fibre is designed specially for optical transmission systems, which operates over the entire wavelength window from 1260 nm to 1625 nm. By suppressing the water peak that occurs near 1383 nm in conventional single mode fibre due to hydroxyl (OH-) ions absorption, FullBand® Plus Fibre is able to open E-band (1360 to 1460nm) for operation, and consequently provides 100 nm more usable wavelengths. FullBand® Plus Fibre is effectively optimized for much lower attenuation level across the entire wavelength window from 1260 nm up to 1625 nm. The fibre is fully satisfying the demands for transmitting with high-speed, in multi-channel and extended networking distances over one single fibre.
