Low water peak in dispersion-shifted single-mode fiber, the performance meet or exceed the ITU -t g. 652 d and IEC60793-2-50 B1.3 type optical fiber. It is suitable for the 1260 nm to 1625 nm all band transmission system. It eliminates the conventional single mode fiber caused by hydroxyl ions near 1383 nm wavelength absorption peak water, enlarging working window to E wavelength (1380 nm to 1480 nm). Attenuation and dispersion characteristics of optical fiber in all band was optimized, to satisfy the multi channel on the single fiber, the requirement of high rate transmission.
