Scope

This standard specifies the geometrical, optical, transmission characteristics, mechanical and environmental performance requirements of the B1.2 cut-off wavelength shifted single-mode fiber in GB/T 15972.1. The zero dispersion wavelength of this type of fiber is around 1310nm, the cut-off wavelength is shifted to a longer wavelength, the attenuation is the lowest in the 1550nm wavelength region, and the best working wavelength is in the range of 1500-1600nm. The single-mode fiber specified in this standard is suitable for communication networks and other communication equipment.
