Hi there!
This time, I will share with you about 10G service maintenance suggestions.
Fault symptom
10G services on OSN 8800 layer interrupted
Three 10 G Services impacted for more than 20 seconds.
Handling Process
Discovered by inspection that the input optical power fluctuated for about 2.2dB in-line boards which were probably triggered by abnormal fiber conditions. Then lots of code errors appeared on receiving side of the 8030 sites, and finally resulting in service interruption. Both the working and protection line boards received many line code errors.
Handling Method
1. Checks the related fiber connectors. If the fiber connectors are dirty, clean or replace them.
2. If the alarm persists, check the fiber jumper. If the fiber jumper endures a large bending radius or it is damaged or aging, adjust or replace the fiber jumper.
3. The Huawei optical interface connector is well inserted.
4. The fiber connector is clean.
5. The cable is intact.
6. Add or remove some optical attenuators so that the optical power is proper.
7. Check whether the fiber is damaged. If yes, replace the fiber,
8. If bit errors still occur, replace the line board that reports bit errors at the local station.
Subsequent maintenance comments:
1. Please take into the process of the link optimization activity.
2. OSNR should be monitor on a routine basis.
That's all, I welcome everyone to leave a message and exchange in the comment area!
Thank you！
