To Single Mode or Multimode? That is the Question.

What is the difference between Single Mode Fiber (SMF) or Multimode Fiber (MMF) exactly? From a physical standpoint, MMF has a bigger core compared to SMF which allows for a longer wavelength of light. MMF typically uses Light-Emitting Diodes (LEDs) to launch the optical signal. SMF’s core diameter is much smaller than MMF.  Also, SMF uses [...]
