acdSfpThreshTxPwrLowWarn
Module: ACD-SFP-MIB
OID (symbolic): ACD-SFP-MIB::acdSfpThreshTxPwrLowWarn
OID (numeric): 1.3.6.1.4.1.22420.2.4.3.1.18
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Low Warning TX output power in mW. Represented as a 16 bit unsigned integer with the power defined as the full 16 bit value (0 to 65535) with LSB equal to 0.1 micro-Watt, yielding a total range of 0 to 6.5535 mW (~ -40 to +8.2 dBm).
What is acdSfpThreshTxPwrLowWarn?
This OID specifies the low warning threshold for TX optical power, triggering advisories about marginal transmit signal strength (0–6.5535 mW, roughly -40 to +8.2 dBm). Early warning of weakening laser output allows teams to schedule maintenance before the link becomes unstable. A threshold of 5000 (0.5 mW or -3 dBm) alerts when transmit power is below optimal, giving time to clean optics or replace the module.
