Troubleshooting Optical Module Issues Symptom An optical port cannot go Up. The optical module cannot be properly identified and optical module information cannot be obtained. After
To further troubleshoot and clear this alarm, perform the following steps: Check the channel plan at the system level and verify if the OTS-OCH power levels of the amplifier meet the expected
If it is not a Huawei-certified optical module, replace it with a Huawei-certified optical module. If the optical module is installed on a GE port, run the display interfaceGigabitEthernet x/x/x command to
What Does Alarm Information Mean in Optical Module Information? When you run the display transceiverinterfaceinterface-type interface-numberverbose command to view information about a
Check whether the receive power of the optical module is within a usable range. If so, run the transceiver diagnosis threshold rx-power command to change the receive power lower threshold
This article helps engineers quickly identify optical module installation issues and take targeted measures to restore network operations. We recommend saving this article as a tool
Quick reference for interpreting Digital Optical Monitoring (DOM) values on fiber optic modules (SFP, SFP+, QSFP, etc), identifying acceptable, caution, and unacceptable levels, and general issue
Check the diagnostic information, which shows that the received optical power is low, with a threshold of -3 to -23.01, currently at -22.84. Once it exceeds the threshold, an alarm will be
When the port status is UP, but it does not receive or send messages, troubleshoot from the following three aspects: The first step is to check the port message statistics. Check whether the

The Equipment Failure alarms is rasied on an optical module equipment that has an internal failure or is not able to commucate with the NCS1001 chassis. Clear the EQPT-FAIL-<n> Alarm
The possible cause of the LASER_MODULE_MISMATCH alarm is as follows: 1.The optical port type supported by the physical board does not match the type of the opticalmodule
How to clear Unavailable Optical Module Alarm | SFP Module Alarm | ZTE BBU Current Alarms In this video you can learn that How to clear Unavailable Optical Module Alarm.
Check whether the peer port is physically Up and whether there is no alarm indicating that the transmit power is too low. If so, perform an external loopback test on the interface.

Context If optical modules that are not certified for Huawei data center switches are used on devices, the devices will generate a large number of alarms to prompt users to replace these optical modules with
1. TxFault optical module status is automatically detected by the XFP module inside and send it out via pin NR (NOT READY), software is responsible for the results of the display module
Have you ever experienced an unexpected network outage due to the failure of an SFP/SFP+ optical transceiver? Network outages can bring your ability to communicate and work to a
Impact on the System If this optical module was delivered from Huawei early, this alarm does not affect the system. If not, the optical module may not work normally.
First, check whether the status of the optical port is on, and then check whether the optical module parameters of both ends are matched (such as wavelength,
If an alarm appears, it means that the optical module is faulty or the optical module does not match the optical interface type. Optical Power-Use the optical power meter to test whether the
Check whether the transmit optical power and receive optical power of the optical module are within the normal range. If the transmit optical power is beyond the normal range, replace the
Based on typical issues encountered with optical modules in daily switch applications, this document summarizes basic troubleshooting steps for resolving common faults:
The alarm does not include the SN or BOM code of the component. This alarm is generated when the system failed to obtain the temperature of the optical module on the mainboard. Alarm object:
However, vendor information of Huawei early-delivered optical modules may not be recorded. Therefore, non-Huawei-certified switch optical module alarms are generated. These optical
Impact on the System This alarm does not affect system operating if the interface on which the optical module is installed works properly.
Possible Causes Cause 1: The optical module is not a Huawei-customized optical module. If this optical module was delivered from Huawei early. Cause 2: Temperature of the
In this article, we discuss the main reasons and solutions for optical transceiver connection failures, which may help you with diagnosing common module issues.
