On: Creating a bespoke data diode for air‑gapped networks

[MisterTea]

The point is you don't need the opto isolator at all.

That's a separate point. Are you agreeing that if an air gap was needed an optoisolator would be suitable?

No. "An air-gapped computer or network is one that has no network interfaces, either wired or wireless, connected to outside networks" https://en.wikipedia.org/wiki/Air_gap_(networking)#Use_in_cl...

"For this reason, some new hardware technologies are also available like unidirectional data diodes or bidirectional diodes (also called electronic airgaps), which physically separate the network and transportation layers and copy and filter the application data. "
