The following are the standards for single mode optic fiber as given by several international committees. Single mode fiber with a relatively narrow diameter, through which only one mode will propagate typically 10nm or 1550nm. If mode conditioning patch cables are not used, and instead a normal multi mode fiber is used with a single mode transceiver module, the single mode transceiver module will launch the light directly in the center of the cable, causing multiple light signals to be generated thus confusing the receiving module.

This means that the core to cladding diameter ratio is 9 microns to 125 microns. The first is a relatively simple way, for indoor optical fiber, can be singlemode fiber andmultimode fiber to identify the external color, singlemode optical fiber cable is yellow, while the multimode is red.
