What is the core diameter of OM2 and OM3 multimode fiber?

Explanation:
In multimode fiber, the core diameter is the key dimension that determines how many light modes can propagate. For OM2 and OM3, the standard core diameter is 50 micrometers (with a 125 micrometer cladding). This size is what defines their typical performance and compatibility. The 62.5 micrometer option comes from older OM1 fiber, while the millimeter-scale values are not used for fiber cores. So 50 micrometers is the correct core diameter.
