Check whether the receive power of the optical module is within a usable range. These thresholds are determined through extensive testing and verification. However, this is not recommended. If an opti...

Page 5 If the test result exceeds the upper limit of the Rx optical power, optical attenuator can be added on the ONU side to reduce the input optical power of the MA5833.
If the connected optical modules have the same wavelength and provide short-distance transmission but alarms indicating low or high optical power occur, the two optical modules may be from different
How Can I Determine Whether an Optical Module Is a Huawei-Certified Optical Module? A switch must use optical or copper modules that have been certified for use on Huawei switches.
Using the optical-module threshold tx-power command, you can set the lower and upper alarm thresholds of the transmitting optical power for the optical module on a passive optical network
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. The
The lower alarm threshold and upper alarm threshold of the transmitting optical power are set for the optical module. The recommended value of lower-limit is -1.00.

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
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 upper threshold
The A0 registers of some non-Huawei-certified optical modules are set incorrectly. As a result, parameters and diagnostic information cannot be read or read incorrectly by the data bus.
