Look at the writing (print) on the cord

If you can see any markings for 7 or 9 microns then it is SM

50 or 62.5 is MM

Hi Mahesh,

Usually (not always) if the fiber is yellow, it is single mode, if it is orange or aqua is MM.

If the fiber is single mode, make sure your optic is also single mode.

Orange = multi-mode

Yellow = single-mode

That has been my experience for many years.
