G.652.D Standard Single-Mode Optical Fiber Product Introduction Standard  single-mode  fiber  is  also  called  non-dispersion-shifted  single-mode  fiber with extended wavelength band that is currently the most widely used optical fiber. The working wavelength can be from 1310nm and 1550nm. Application Scenarios The wider wavelength range is suitable for high-speed networks. Accurate mode field diameter (MFD) characteristics to ensure low fusion loss and good compatibility. Performance Features 100G & B100G high-speed, long-distance and long-span backbone network. Large bandwidth metropolitan area network and access network. Product Specification
