acdSfpThreshRxPwrLowWarn
Module: ACD-SFP-MIB
OID (symbolic): ACD-SFP-MIB::acdSfpThreshRxPwrLowWarn
OID (numeric): 1.3.6.1.4.1.22420.2.4.3.1.22
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Low Warning RX input 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 acdSfpThreshRxPwrLowWarn?
This OID specifies the low warning threshold for received optical power, alerting to weakening signals before they cross below the critical alarm point (0–6.5535 mW range). Early warnings allow network teams to investigate fiber degradation or optical component aging before the link goes down. A threshold of 2000 (0.2 mW or -7 dBm) warns when received power is fading but still usable, prompting fiber inspection or cleaning.
