What are the differences between SM fiber and MM fiber?

 MM fiber Concept   MM fiber is a fiber that transmits multiple modes at a given working wavelength. When the geometric size of the fiber is much larger than the wavelength of the light wave, there will be dozens or even hundreds of propagation modes in the fiber. Different propagation [ Continue reading…]
