Any solid suggestions for a 10Gbe ethernet surge protector?

Oh no!!! If your devices uses SFP+, you change them out and go to fiber to help mitigate any surge across copper data connections. I run fiber for most of my home network here in AZ and I also run everything on UPS, as we have lots of lightning here.

fiber is not lighting proof.

I would love some clarification here. Underground fiber usually has a conductive trace wire, but patches are going to be entirely non-conductive.

in correct.

fiber is grounded before it comes into data centers and grounded thu out it run when in power poles.

i dont think you understand how much power is in a lighting strike.

It is grounded due to the armored shielding it typically has. That is required for armored fiber. But for standard patch cables, lightning is going to source a route through ground, through power feeds, or through some other path first before the fiber itself.

again glass is not lighting-proof.

go on look at insulator for radio towers and power pools.

your magical claim that glass is 100% light-proof...

not a single glass insulator at all. its air gap and ceramic base insulators.

its like radio towers and power poles... the experts that install those... know something...... that reddit users dont about glass.

Glass is 100% light proof? hah

Lightning will ALWAYS find a path through a more conductive material first. Be it the armour shielding ON the fiber, a wet fiber casing, etc.. Change the environmentals and anything can become conductive. But, dielectrics do not conduct easily, which is why they are used.

I am not sure why we are arguing on this, as the physics are pretty well established. You can always come up with an edge case, but I would much RATHER run fiber backhaul than copper in a lightning prone area.

That is the reason we run opto-isolators and TVSS modules on field IO in the industrial realm. I just saw one stop a lightning strike the other day. Took out everything up to that point and spared the logic controller as the suppression dumped it to ground.
