Oculus' consulting technology chief John Carmack continues to tweet about VR technology. This time: Oculus Link.
On the paper offers the PC connection for Quest with Oculus Link not the same image quality as a native PC connection, as the PC content is streamed as a compressed video rather than native. This compression should theoretically reduce image quality and add latency. Theoretically, because both disadvantages in Oculus Link Test do not notice.
Independent of this, Oculus technician John Carmack is adding more on Twitter Improvements for Oculus Link in the prospect: There are plans for a transmission mode, which fully exploits the advantages of USB 3.1. The upgrade is still a few months away from the release.
I have hoping to add a USB3.1 bandwidth that would have been out of hand.

A potential bottleneck at higher USB transfer rates is the limited processing power of the Quest processor, which needs to decompress the compressed video stream without increasing latency.
This problem is solvable, says Carmack, also is the current Oculus Link version not yet at the resolution limitto improve compatibility with PCs. "It will go up as soon as we have more data," promises Carmack.
Extra long Oculus link cable thanks to fiber optics
Meanwhile, first users try the technical Limits of the cable connection auszureizen. The Twitter user "Ilja Z" was able to successfully route the Oculus Link's USB-3 signal via a fiber optic converter through a 30-meter-long fiber-optic cable to the Quest glasses.
Theoretically, cable lengths are supposed to be that way from up to 250 meters be possible with whom you can VR goggles could use across multiple rooms or on the sports field.
So I did a thing with #OCULUSLINK, I connected through 30m optical fiber and it works. Theoretically it can go up to 250 meters on a single cable. Freedom! pic.twitter.com/V0oCzIyU3r

However, fiber optic converters and long fiber optic cables cost many hundreds of extra euros. Oculus' original cable for Link also sets Fiber optic technology at a length of five meters. The price is 80 US dollars.
USB 3.0 compatible fiber optic cables with integrated converter with a length of 50 to 100 meters cost between 400 and 500 Euro (Amazon Examplelink).
