Q2: Single mode vs multimode selection rule? Multimode for cabling under 500 meters, singlemode for transmission above 2 kilometers. Q3: LC or SC is more commonly used? LC
How to Tell if Fiber is Multimode or Singlemode: A Comprehensive
So, an LC connector on an orange cable is likely multimode, and an LC connector on a yellow cable is likely singlemode, based on the associated cable jacket color and markings.
How to Tell the Difference Between Single Mode and Multimode Fiber?
Fiber Color: This is often the easiest visual cue. Single mode fiber is typically yellow. Multimode fiber usually comes in orange (OM1 and OM2), aqua (OM3 and OM4), or lime green
How to tell the difference between single mode and multimode fiber
When in doubt, checking the cable specifications, looking at the color, and knowing the intended application can help you identify whether a fiber optic cable is single-mode or multimode.
