Which OM fiber categories are tested with LED sources for LAN testing?

Explanation:
LED sources are used for testing older multimode fibers because LEDs provide a lower-bandwidth, broader-spectrum light that matches the capabilities of the earlier OM1 and OM2 categories. These categories were designed around LED-based transmission, so LAN testing with LEDs is appropriate for them, reflecting the speeds and distances those fibers were meant to support. In contrast, OM3 and OM4 were developed for higher-bandwidth, VCSEL-based systems to enable faster LAN links, so LED testing isn’t suitable for them.
