sheEthernetPortSfpRxPower
Module: SHE-ETHERNET-MIB
OID (symbolic): SHE-ETHERNET-MIB::sheEthernetPortSfpRxPower
OID (numeric): 1.3.6.1.4.1.231.7.1.2.2.1.5.1.1.1.25
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Measured RX received optical 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). Absolute accuracy is dependent upon the exact optical wavelength. For the vendor specified wavelength, accuracy shall be better than 3dB over specified temperature and voltage. This accuracy shall be maintained for input power levels up to the lesser of maximum transmitted or maximum received optical power per the appropriate standard. It shall be maintained down to the minimum transmitted power minus cable plant loss (insertion loss or passive loss) per the appropriate standard. Absolute accuracy beyond this minimum required received input optical power range is vendor specific.
Only valid if sheEthernetPortSfpDiagnosticValid entry is true.
What is sheEthernetPortSfpRxPower?
This read-only Unsigned32 (0-65535, in units of 0.1 microwatt per SFF-8472 table 3.17) reports the SFP's measured received optical power, valid only when sheEthernetPortSfpDiagnosticValid is true. An admin monitors this to catch a degrading fiber link, dirty connector, or failing remote transmitter before the link actually drops. A steadily declining sheEthernetPortSfpRxPower over time would tell an admin to inspect and clean the fiber connectors or check the remote-end transmitter before the link fails outright.
