The switch s optical port cannot connect after a power outage

The optical module used is not a switch-certified optical module. I have a problem with the SFP module on my C3750 Switch. There is a File Server connected to one of the ports on the module (there are 3 Gi ports) and whenever there is a power outage the module stops working and there is no access to the File Server, i thought the port that the SFP module was. SFP issues are among the most common and frustrating problems in fiber optic and Ethernet networking environments. Whether you are dealing with a no link light, intermittent connectivity (link flapping), or a transceiver not detected error, the root cause is often not immediately obvious. In many. If you have physical access to the switch, it can save time to look at the port LEDs which give you the link status or can indicate an error condition (if red or orange). But when I got to the site, I completely unplugged the power again, rebooted the switch, and the ports will work well again, This is very strange.

Why do we need to connect an optical module to the optical port

In the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks. Protects optical fiber connectors, adapters, and ports from external contaminants and damage. Spring Ensures a secure connection between the optical module and the device's optical port.
