The solution is to unplug the fiber and reinsert it into the SFP module interface until a “click” sound is heard, indicating the fiber connector and SFP module are properly connected. Contamination or damage on the fiber end face requires the use of a fiber end-face. The optical module cannot be properly identified and optical module information cannot be obtained. After an optical module is inserted, the console port displays alarm information. These faults can affect network stability and, in severe cases, cause network interruptions, resulting in losses. Therefore, it is important to be proficient in identifying and troubleshooting. Customers in the use of optical modules will more or less encounter a variety of failure problems, such as optical module model selection is correct, the use of jumper is correct and some common problems, customers have the ability to judge and have a clear solution, but for some of the use of. SFP transceivers are essential components in modern networking, enabling seamless communication between switches, routers, and optical fibre networks.
