If possible, remove and reinstall the optical modules to check whether the fault is rectified. 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. Is this related to DS110DF111? How can it be solved I wouldn't expect repeated insertion/removal of the optical module to. 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. Optical modules, including the advanced 25G SFP28 transceiver, play a pivotal role in modern communication systems, facilitating the transmission of optical signals. These five values tell you exactly where the problem is — if you know how to read them.
Solution: Check whether the working parameters, interface information and receiving and sending of the optical module are normal, and then check the optical fiber jumper, or try to replace the optical fiber
