Oculus' consulting technology chief John Carmack continues to tweet about VR technology. This time: Oculus Link.<\/strong><\/p>\n

On the paper offers the PC connection for Quest with Oculus Link<\/strong> 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<\/a> do not notice.<\/p>\n

Independent of this, Oculus technician John Carmack is adding more on Twitter Improvements for Oculus Link<\/strong> 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.<\/p>\n

\n

I have hoping to add a USB3.1 bandwidth that would have been out of hand.<\/p>\n

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.<\/p>\n

This problem is solvable, says Carmack, also is the current Oculus Link version not yet at the resolution limit<\/strong>to improve compatibility with PCs. "It will go up as soon as we have more data," promises Carmack<\/a>.<\/p>\n

Extra long Oculus link cable thanks to fiber optics<\/h2>\n

Meanwhile, first users try the technical Limits of the cable connection<\/strong> 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.<\/p>\n

Theoretically, cable lengths are supposed to be that way from up to 250 meters<\/strong> be possible with whom you can VR goggles<\/a> could use across multiple rooms or on the sports field.<\/p>\n

\n

So I did a thing with #OCULUSLINK<\/a>, 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<\/a><\/p>\n

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<\/strong> at a length of five meters. The price is 80 US dollars.<\/p>\n

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<\/a>).<\/p>\n
