Description: The optical power transmitted at the Tx port in units of 0.1 dBm.
What is dcpInterfaceTxPower?
This value reports the optical power transmitted out the interface's Tx port, expressed in units of 0.1 dBm. An admin checks it to confirm the local transceiver is putting out enough light for the far end to receive a clean signal, and to spot a failing laser. For example, a healthy SFP might read 20 (2.0 dBm), while a value trending toward 0 or negative over time suggests the transmitter is degrading and due for replacement.
