I tore down oculus link cable - it's just copper internally.

Also oculus works fine over the "charging" type c cable + type-c to type-a + a classic copper usb3.0 extender of another 1.8 meters.

I use it for other things and it performs admirably. (In particularly my Sony camera has trouble with cheap cables) It is one of two "elite" USB-C cables I keep near my computer, the other one is the shorter cable that came with the Looking Glass Go.
