An enhanced optical module has two thresholds for optical power: a warning threshold and an alarm threshold.
When the receiving power of an interface falls below the lower warning threshold, packets may be lost on the interface, but the interface does not enter the linkdown state.
When the receiving power of an interface reaches the lower alarm threshold, severe packet loss may occur, or even the interface enters the linkdown state. A high receiving power may corrupt an optical module.
