SFM fiber is single-mode

Single mode fiber (SMF) is a type of fiber optic cable that only allows one light mode to transmit at a time. Generally, single mode cable has a narrow core diameter of 8 to 10µm (micrometers), which can propagate at the wavelength of 1310nm and 1550nm. "What is the difference between single-mode SFP and multimode SFP, and which should I choose in 2026?"...
