SmartAX MA5600T/MA5603T Multi-service Access Module Troubleshooting: ONU Frequently Goes Online and Offline: TC-C6214 ONU Frequent Going Online and Offline Because of a Too Large Split Ratio, also the MA5616 works, too.
Fault Description
Network topology: Originally, the system uses one-level optical split and the split ratio is 1:8. Later, the customer connects a 1:16 optical splitter to the 1:8 optical splitter. The three ONUs are connected to the 1:16 optical splitter.
During deployment in an office, three ONUs frequently go online and offline.
Alarm Information
None
Possible Cause
l The ONU receive optical power is larger than the overload optical power.
l The ONU receive optical power is smaller than the sensitivity.
l There is abnormal attenuation on ODN lines.
Procedure
Step 1 Test the ONU receive optical power. It is found that the receive optical power of the three ONUs is approaching the sensitivity.
Step 2 Analyze the total split ratio of the three ONUs. It is found that the total split ratio is 1: (16 x 8) = 1:128, which is too large and therefore causing too large attenuation, as shown in Figure 1.
Figure 1 Too large split ratio
Step 3 Change the 1:16 optical splitter to a 1:4 one. Then, the fault is rectified.
Step 4 Such a fault does not recur in the next week.
—-End
Suggestion and Conclusion
Bit errors will occur on an ONU if the ONU receive optical power is approaching the sensitivity and even the ONU may go offline. Reserve a 3 dBm attenuation margin in ODN planning.
NOTE
The specifications of the optical path attenuation are as follows (the following are theoretical values and the actual values vary with the environment):
l The optical attenuation on the ONU GPON port should be within the range of 15 dBm to 25 dBm.
l The attenuation on an optical fiber is about 0.3 dB per kilometer.
l The attenuation for an optical splitter is as follows:
l 1:2 optical splitter: 3 dBm
l 1:4 optical splitter: 6 dBm
l 1:8 optical splitter: 9 dBm
l 1:16 optical splitter: 12 dBm
l 1:32 optical splitter: 15 dBm
l 1:64 optical splitter: 18 dBm
5 ONU Frequently Goes Online and Offline(1) – a Rogue ONU
SmartAX MA5600T/MA5603T Multi-service Access Module Troubleshooting: ONU Frequently Goes Online and Offline: TC-C6217 ONU Frequent Going Online and Offline Caused by a RogueONU.
This topic describes how to troubleshoot the fault of ONU frequent going online and offline.
Fault Description
All ONUs connected to a port in an office frequently go online and offline after a flood.
Alarm Information
Rogue ONU alarm
Possible Cause
l The ONU receive optical power is larger than the overload optical power.
l The ONU receive optical power is smaller than the sensitivity.
l There is abnormal attenuation on ODN lines.
Procedure
Step 1 After communicating with the customer, we learn that there was once a flood some ONUs are flooded.
Step 2 Analyze the condition. Only certain ONUs are flooded. This should not cause all ONUs to go offline repeatedly. It is concluded that the optical modules of certain ONUs transmit signals abnormally because of flood and the ONUs become rogue ONUs.
Step 3 Check optical lines one by one near the optical splitter. It is found that one ONU works in the continuous mode, as shown in Figure 2.
Step 4 Replace the ONU. System services recover.
Step 5 Such a fault does not recur in the next week.
—-End
Suggestion and Conclusion
In normal conditions, ONU signal transmit timeslots are controlled by the OLT. A rogue ONU is an ONU that goes out of control of the OLT and works in the continuous mode or irregular mode. You can locate a rogue ONU manually or locate a rogue ONU by querying alarms generated on the OLT. If a rogue ONU is detected, replace it in time.
SmartAX MA5600T/MA5603T HG8010 GPON Terminal Multi-service Access Module Troubleshooting: ONU Frequently Goes Online and Offline: TC-C6208 ONU Frequent Going Online and Offline Because of a Too Small Fiber Bend Radius
This topic describes how to troubleshoot the fault of ONU frequent going online and offline.
Fault Description
Network topology: Optical split level: one level; split ratio: 1:32; backbone fiber: 8.6 km long; branch fiber: 1.5 km long. In an office, an ONU frequently goes online and offline.
Alarm Information
LOSi alarm and LOFi alarm
Possible Cause
l The ONU receive optical power is larger than the overload optical power.
l The ONU receive optical power is smaller than the sensitivity.
l There is abnormal attenuation on ODN lines.
Procedure
Step 1 Test the receive optical power on ONU optical ports. It is found that the receive optical power is only -28 dBm. This indicates that there is abnormal attenuation on ODN lines.
Step 2 Check field conditions. It is found that fibers are placed disorderly, the fiber bend radius is too small and the fiber is almost broken, as shown in Figure 1.
Figure 1 Too small fiber bend radius
Step 3 Replace the fiber and test the ONU receive optical power again. -18 dBm optical power is obtained and services recover. This indicates that the too small fiber bend radius causes abnormal attenuation on ODN lines and consequently causes the ONU to go online and offline frequently.
Step 4 Such a fault does not recur in the next week.
—-End
Suggestion and Conclusion
Make sure that the fiber bend diameter is larger than 8 cm when bending a fiber.
SmartAX MA5600T/MA5603T Multi-service Access Module Troubleshooting: ONU Frequently Goes Online and Offline: TC-C6207 ONU Frequent Going Online and Offline Because ofMismatching Fiber Connector, and how to solve the similar product MA5606T, MA5616 troubleshooting, you can referce from this chapter, too.
Fault Description
Network topology: Optical split level: one level; split ratio: 1:32; connector: SC/APC connector. In an office, an ONU frequently goes online and offline.
Alarm Information
LOSi alarm and LOFi alarm
Possible Cause
l The ONU receive optical power is larger than the overload optical power.
l The ONU receive optical power is smaller than the sensitivity.
l There is abnormal attenuation on ODN lines.
Procedure
Step 1 Test the receive optical power on ONU optical ports. It is found that the receive optical power is -27 dBm. This indicates that there is abnormal attenuation on ODN lines.
Step 2 Perform a test on the optical splitter. It is found that the connector of the optical splitter is an SC/APC connector but that of the ONU fiber is an SC/PC connector. When an APC-endface fiber is connected to a PC-endface fiber, at least 3 dB attenuation will be generated, as shown in Figure 1.
Figure 1 Interconnection of PC and APC connectors
Step 3 Remove the SC/PC fiber (blue) and splice it to an SC/APC fiber (green). Test the ONU receive optical power again. It is found that the receive optical power becomes -23.5 dBm, which is within the normal range. This indicates that the mismatching fiber connector causes abnormal attenuation on ODN lines and consequently causes the ONU to go online and offline frequently.
Step 4 Such a fault does not recur in the next week.
—-End
Suggestion and Conclusion
It is recommended that you connect an SC/PC connector to an SC/PC connector (or an SC/APC connector to an SC/APC connector). The biggest difference between an SC/PC connector and an SC/APC connector lies in that the endface of an SC/PC connector is a plane but the endface of an SC/APC connector is a slop. If an SC/PC connector is connected to an SC/APC connector, at least 3 dB attenuation will be generated.
SmartAX MA5600T/MA5603T Multi-service Access Module Troubleshooting: ONU Frequently Goes Online and Offline:
The ONU frequently going online and offline failure is a fault in which an ONU connected to aPON port of an OLT frequently goes online and offline and therefore the OLT reports a large number of ONU LOS and ONU signal recovery alarms.
There are several reasons if the ONU frequently goes online and offline, we will tell the detailed on this blog.
1 TC-C6007 An ONU Goes Online and Offline Repeatedly Because of
Unstable Voltage
This topic describes how to troubleshoot the fault when an ONU goes online and offline
repeatedly and alarms that the ONU goes online and offline repeatedly are generated on the OLT because of unstable voltage.
Fault Description
An ONU connected to an OLT in an office goes online and offline repeatedly and irregularly.
Alarm Information
Alarms that the ONU goes online and offline repeatedly are generated on the OLT.
Cause Analysis
l The optical fiber attenuation is very large.
l The hardware of the ONU is faulty.
l The boards on the OLT are faulty.
Procedure
Step 1 Other ONUs connected to the PON port are normal, which indicates that the PON board of the OLT is normal.
Step 2 Use an optical power meter to test the optical fiber attenuation on the ONU side. It is found that the optical fiber attenuation is -20 dB, which is normal. This indicates that the line is normal.
Step 3 Replace the ONU with another ONU. The fault, however, persists, which indicates that the hardware of the ONU is normal.
Step 4 The ONU on which the fault occurs is located in a remote mountain area. Therefore, it is suspected that the fault is caused by the surroundings. Log in to the ONU in the telnet mode, and then run the display alarm list all command to carefully view the alarms. It is found that the ONU resets in peak hours from 7:00 a.m. to 8:00 p.m. in four consecutive days. Therefore, it can be preliminarily determined that the fault is caused by the voltage.
Step 5 Use a multimeter to test the voltage on site. It is found that the ONU resets repeatedly due to unstable voltage. Replace the ONU with another ONU with the DC module. As a result, the fault is rectified.
—-End
Suggestion and Conclusion
The ONUs of Huawei support AC power supply and DC power supply. If an ONU uses the AC power supply, the ONU resets repeatedly when the voltage is unstable. If the voltage is abnormal and the normal voltage cannot be guaranteed, it is recommended that you use an ONU with the DC module.
