"NettetIn improved fibers, the internal impurities are practically negligible. The largest loss is caused by OH-ions and these cannot be sufficiently reduced. Because the OH impurity causes loss for particular wave length bands, the worst loss (about 4 dB/km) occurs near λ = 1.4µm for an impurity concentration of 1ppm.
