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.
The wider wavelength range is suitable for high-speed networks.
Accurate mode field diameter (MFD) characteristics to ensure low fusion loss and good compatibility.
The characteristics of a single-mode optical fibre and cable with zero-dispersion wavelength around 1310 nm, but which can also be used in the 1550 nm region.
