What is Mode Field Diameter

In this video, I will go over what the Mode Field Diameter of a fiber optic cable is and how it differs from core size. I will talk about the different single-mode fibers out there and how MFD miss-match looks on an OTDR and how to analyze it. With the EXFO OTDR I will look at gainers and losers and explain just what we are seeing. I hope you enjoy this video.
