If so, rectify the peer optical module fault first. Check whether the peer optical module and the local optical module are of the same type. If not, replace the local optical module with a new one

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

Upper and lower alarm thresholds are set for the transmit power of the optical module on the interface. This document describes the principles and configurations of the Device Management features, and

When the receive or transmit power of an optical module exceeds the upper threshold or falls below the lower threshold, the optical module may fail to work properly.

When the transmit/receive power of the optical ports is too high, optical modules on the ports may be damaged. In this case, connect an attenuator to the optical modules.

Although these optical modules have the same wavelength, optical power alarms occur because different vendors design different optical power indicators for these optical modules.

You can set optical power alarm so that the device generates alarms if the transmit or receive power of an optical module exceeds a threshold. An alarm may indicate that the optical module is faulty.
