0x2e11a001 The feeder fiber is broken or OLT can not receive any expected optical signals(LOS) Today i will discuss about 0x2e11a001 The feeder fiber is broken or OLT can not receive any expected optical signals(LOS) alarm. System generates this alarm When no signal is detected on the PON port. [boxads] Attribute: Alarm ID Alarm Severity Alarm Type 0x2e11a001 Major Fault Impact on the System: The PON port cannot receive any signal and cannot transmit data. Therefore, services of all the ONTs connected to the PON port are interrupted. Possible Causes: The laser of the port is shut down. The backbone …
