So, I recently experienced cable issues when I wanted to get into my VR experience like probably a good amount of people have experienced it. To be clear, I'm no expert by any means. I can only share what I read and found out myself. I would love to hear back what can be done or what exactly is going on. Preferably from someone who actually worked or works on these things at Oculus. Enough of the introduction, let's get into it. My cable broke somewhere inside, give it a little wiggle and it drops out. Give it another and you maybe get a connection back until it wiggles a bit again. I'm very excited for the replacement coming in. Thank you for that already. First off, maybe thicker wiring would improve overall strength of the cable, but would come with the tradeoff of being less flexible probably. Really depends how thick you're going. Second off, this Headset is Cable only (at least as the time of writing this) and therefore this is a part that most likely gets the most wear and tear in the whole system, depending on the user. It definitely is a part that can and will break at some point. So, if there is any way of getting to buy one or multiple, in case someone wants to keep spares, that would be awesome. Not only would Oculus do some sales (in my opinion, don't know how if it would be a big profit maker, but definitely gets you some reputation points for sure), they would also improve reputation and make them more appealing to recommend to others. If you can't get replacements for something that would break at some point for sure, what's the point in buying it to then be left alone in the long run. To be fair, I got a replacement and the support is great, but options for people to buy it, would be so much appreciated. Coming back to the actual cable build quality. I run computer fans on my ceiling and probably will add more in the future. Yes, not everyone would do that and certainly there probably isn't many people doing that. But what I found out is, 12 Volts can easily disrupt the visual signal if it gets too close to the cable. Running DC fans, they ramp up in voltage depending on their Speed. Up until 12 Volts. I've tested DC and PWM. The more you get to 12 Volts, the more I could see green, blue and red pixels dancing around or being static. Atleast for the last pieces of signal I could get out of the cable. This becomes especially noticeable if it happens in the middle of the screen for example. PWM btw always runs on 12 Volts. My conclusion from that is shielding. I didn't took the cable apart. So I can't guarantee my assumption is correct. But I assume either foil shielding or no shielding (which would surprise me tbh and isn't really acceptable by any means.) From my Experience and work with CAT 7 Ethernet Copper cables (Yes fiber is better at some point and Ethernet and Displayport isnt the same, but at the end of the day they both carry a fair amount of data at a given point) You're best with an S/FTP cable. Especially when you route it next to a power line (for example 220-240 Volts in my country). S would be the indicator for a metal or copper braided shielding. F is the indicator for foil shielding and TP means twisted pair. In an S/FTP cable, the foil shielding is around every twisted pair. This means, multiple foils and one copper braiding around all of that. Getting back to the Rift S cable, I don't know how much more effective a braided shielding is to be honest, but that could be a consideration. If its not much different (which I doubt but I could be wrong), we definitely need more layers then. Maybe a braiding inside the cable could also improve cable strength. As for the other parts of the cable goes, besides shielding, from specifications the Rift S is rated for 1 Amp on 5 Volts. USB 3.0 (USB 3.1 Gen 1, thank you Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel for that nonsense) on the other hand, officially spits out a maximum of 0,9 Amps on 5 Volts. If that would help with signal strength or generally better power supply to everything, add another USB Cable for power delivery or something like that. From what I found and roughly calculated, the Rift S is around 8Gbits of Bandwidth on 1440p at 80Hz. That comes close to cat 7 copper (10Gbit). Probably need thicker wiring, going from the cables I worked with, being solid and also not really soo thin. Im sure someone is a better expert than me and knows better, but that is my input on that. Thank you for reading it all, I know its a ton of text, but I hope it helps. And for Oculus reading this, you probably can match all this information to the correct support ticket, don't want to call out anyone officially, but give the person I wrote that much text a raise. Or something. They were very nice to talk to and I really appreciate the input and response about my information given. To be fair, people in support probably can't give out technical information or other information, they probably also don't even know or have access to. But atleast it's reached in and maybe and hopefully gets some thoughts about it. Again, hopefully someone can respond with more technical information about this, if they are allowed to. If not, atleast mention that you can't talk about it :) Thank you, I hope this helps
