SFP optical module has no optical power
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. 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. I noticed something odd with a fiber SFP module. But if I unplug it and then plug it back in, the light appears.
