Below are some great videos on the physics and practicalities of single mode fiber. They are Thorlabs videos, so are slanted more towards the use of SMF in a laser lab rather than a telecom setting. They reference a lot of the theory, but also provide a good intuition about how and why SMF works so well. https://youtu.be/FbOXRuBQt_U https://youtu.be/FbOXRuBQt_U https://youtu.be/HvJeXakc8Kc https://youtu.be/HvJeXakc8Kc
