"interface shows its connected" what you mean by connected ?
as per your screenshot the interface down,
1. check both SFP are able to detect.
2. check the fibre distance.
3. check the lights in fibre, if you see light in the right connector. ( if not swap the fibre connector)
Look at the Fibre as suggested above my post it may be worth trying and see if it fixes the issue.
should be like this :
Light ---------------- (No Light)
(No Light) ----------------- light
Hope fully we are talking here dark fibre inside campus.
Inside the sfp module the red light is blinking
I hope someone has explained or warned about looking into the laser with a naked eye.
Cisco SFP-10G-SR module
The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.
Report your results.
Set the port on both sides to autonegotiate the speed/duplex meaning DONT hard code either side, if the mdix is disable use a crossover cable between the two switch's.
