Module: CIENA-CES-PORT-XCVR-MIB
OID (symbolic): CIENA-CES-PORT-XCVR-MIB::cienaCesPortXcvrLowTxPwAlarmThreshold
OID (numeric): 1.3.6.1.4.1.1271.2.1.9.1.1.1.1.14
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Indicates the lower threshold for the Tx power alarm. Units are micro watts.
What is cienaCesPortXcvrLowTxPwAlarmThreshold?
This is usually the more operationally important direction: a transmit-power reading dropping below this threshold on a specific transceiver is a leading indicator of laser degradation, and since it measures the transceiver's own output before the signal even reaches the fiber, it isolates the problem to this optic rather than the cable plant. For example, TxPower falling from a nominal 1000 microwatts to below a 500 microwatt threshold clearly isolates a degrading laser inside this specific transceiver rather than a dirty connector further down the fiber path.
