Need a picture of the wire. It looks like land mine but the single thread is weird
Fibre optic jack that is a little damaged.
Sarcasm at its best. Lol
Seriously, can you post pictures of the end device? Something with part numbers if you can?
All I’m seeing is a circuit board with a cable attached …
It could be anything…
And curiosity about the other panels on the wall… what behind them?
Update
My friend says it may be a wide sfp. Some switches have a variant of a sfp that is about 2 times wider than a standard sfp…
Definitely Fiber like others pointed out, and it may be woth it to see what’s behind the covers next to the wall plate. If CAT 5 is available, and you have a Fiber internet provider, you could have Excellent speeds to wherever the CAT5 drops.
This is fresh spaghetti. There’s most likely a pasta machine inside the wall start diggin’!
Seriously, it’s fiber optics.
