0x2e112006 The loss of frame of ONTi (LOFi) occurs Today i will discuss about 0x2e112006 The loss of frame of ONTi (LOFi) occurs alarm. System generates this alarm when the GPON port receives consecutive invalid delimiters from the ONT. [boxads] Attribute: Alarm ID Alarm Severity Alarm Type 0x2e112006 Warning Fault Impact on the System: The data channel is abnormal and cannot transmit data. The services of the ONT are interrupted. Possible Causes: The optical fiber is faulty. The ONT is abnormal. Procedure: Check the optical fiber. If the optical fiber is not connected properly, reconnect the optical fiber again to …

0x2e112003 The signal degrade of ONTi (SDi) occurs Today i will discuss about 0x2e112003 The signal degrade of ONTi (SDi) occurs alarm. System generates this alarm when a GPON port detects that the signals of an ONT deteriorates and that the BER check error code rate in the upstream direction of the ONT reaches the threshold. [boxads] Attribute: Alarm ID Alarm Severity Alarm Type 0x2e112003 Warning Fault Impact on the System: The data transmission is unstable, and packet loss of the ONT upstream service may occur. The service quality deteriorates. Possible Causes: The quality of the optical path is poor. …

Loss of GEM channel delineation (LCDGi) occurs: Today i will discuss about the loss of GEM channel delineation (LCDGi) occurs alarm. System generates this alarm when delimitation of the GEM frame header is incorrect. The OLT detects HEC check errors of the GEM header in consecutive frames and the ONT goes offline. [boxads] Attribute Alarm ID Alarm Severity Alarm Type 0x2e112002 Warning Fault Impact on the System: The loss of frame (LOF) occurs in the system, and the ONT goes offline. Possible Causes: The optical fiber is faulty. The ONT is faulty. Procedure: Check the optical fiber. If the optical fiber …

Optical module fault Alarm Huawei OLT: Today I will discuss Last down cause: Optical module fault alarm. When you connect a non brand SFP or SFP not match with your OLT version then OLT display Optical module fault Alarm. I face a problem, when i connect a new SFP in H805GPFD board then 0-7 port SFP is working but 8-15 port was not working. When we connect NeoPhotonics Class B+ SFP then it work fine. bellow are the both status. [boxads] Unsupported SFP Status: NMC_Huawei_OLT02(config-if-gpon-0/0)#display port state 8 —————————————————————————- F/S/P 0/0/8 Optical Module status Online Port state Offline xPON MAC …
