dot3ExtPkgOptIfTransmitAlarm
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3ExtPkgOptIfTransmitAlarm
OID (numeric): 1.3.6.1.2.1.155.1.4.1.5.1.13
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: When getting true(1) there is a non-valid optical signal at the transmit of the interface, either a higher level or lower level than expected. When getting false(2) the optical signal at the transmit is valid and in the required range. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface.
What is dot3ExtPkgOptIfTransmitAlarm?
This reports whether the transmit optical signal on this interface is currently outside its valid power range, either too high or too low (true), or normal (false). A true value flags a laser problem that needs attention before it causes downstream ONUs to lose signal.
