sheEthernetPortSfpTxPower
Module: SHE-ETHERNET-MIB
OID (symbolic): SHE-ETHERNET-MIB::sheEthernetPortSfpTxPower
OID (numeric): 1.3.6.1.4.1.231.7.1.2.2.1.5.1.1.1.24
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Measured TX output power. Represented as a 16 bit unsigned integer with the power defined as the full 16 bit value (0 .. 65535) with LSB equal to 0.1 W, yielding a total range of 0 to 6.5535 mW (~ -40 to +8.2 dBm). Data is assumed to be based on measurement of laser monitor photodiode current. It is factory calibrated to absolute units using the most representative fiber output type. Accuracy is vendor specific but must be better than 3dB over specified temperature and voltage. Data is not valid when the transmitter is disabled.
Only valid if sheEthernetPortSfpDiagnosticValid entry is true.
What is sheEthernetPortSfpTxPower?
This read-only Unsigned32 (0-65535, in units of 0.1 microwatt per SFF-8472 table 3.17) reports the SFP's measured transmit output power, noted as invalid when the transmitter is disabled and valid only when sheEthernetPortSfpDiagnosticValid is true. An admin monitors this to confirm the local transmitter is putting out enough optical power for the fiber link's budget. A sheEthernetPortSfpTxPower value well below the module's rated output would tell an admin the local transmitter is degrading and may soon cause link errors at the far end.
