A common failure pattern is: the diode is emitting, but the light never makes it to where you measure it. Run the display esn interface command to check whether the optical module is a Huawei-certified one. Although a non-Huawei-certified optical module can be identified and used, its reliability and stability cannot be. This type of optical module failure mainly includes port not UP, port status is UP but do not receive or send messages, port frequently up or down and CRC error. The article Digital Diagnostic Function (DDM) For Optical Modules describes that DDM function can be used for real-time monitoring and fault location of the module's working status, in which the optical module's transmitting optical power and receiving optical power are the key parameters for.
