The Flooring Expert
ITU-T G652D SM optical fiber
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.
