Singlemode and Multimode are the cable optic we see all the time in cabling. Today we will take a brief look at the differences between these two types of cables.

Point of differenceSingle ModeMultimode
Optical transmission patternLD (Laser Diode), the pattern of light is compressed into a single beam.LCD (Light Emitting Diode), the pattern of light is distributed into several lines.
Core size9 um62.5 um , 50 um
Light SourceLD (Laser Diode), Light Source is expensive.LED (Light Emitting Diode) or Vassel, Light Source is cheaper.
DistanceSend the signal farther because LD will send the signal further. Support work from the building level to the cross-country levelSignal short. Suitable for indoor work or a short distance of 300 meters to 2 kilometers
Cable’s PriceCheap price due to the large amount of usage.Pricey as it does not have a lot of usage.
