Enabling the Optical Module Alarm Threshold Standardization Function

You can enable the alarm standardization function for an optical module to prevent the optical module from reporting alarms when its optical power exceeds the threshold.


The system automatically obtains the vendor-defined power threshold of an optical module and compares it with the actual power. If the actual power exceeds the vendor-defined threshold, an alarm will be generated. However, the vendor-defined power threshold of an optical module may not meet user requirements. If the alarm standardization function is enabled, a unified power threshold is used, and the threshold is calculated based on the optical module transmission distance and bandwidth.

The device has two types of optical module power alarms: warning and alarm. A warning is reported when the difference between the actual power and vendor-defined threshold is not great. It can also be considered as a precaution. Some optical modules can continue working properly when the actual optical power is at the warning level. You can disable warning detection as required.
