Description: This is to indicate if the Receive Power reaches or underpasses the Low alarm threshold.
What is acdSfpThreshStatusRxPwrLowAlm?
This OID tracks whether the received optical power has dropped to or below the low alarm threshold, signaling a critically weak signal. Engineers use this to immediately detect fiber cuts, unplugged cables, or failed transmitters on the remote end. A true reading means the signal is so weak that the link is at risk of becoming completely unusable.
