I never knew that USB-C extensions are not allowed for a reason
There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.
You're viewing a single thread.
If you want a more detailed explanation, USB-C is a small connector that was designed primarily for data transfer, extended power range delivery (240w) was essentially hacked on to the standard. Electricity arcing between the contacts on the connector is the biggest challenge with this hack, since the contacts are small and very close together, which could burn out the circuit board and start fires. For EPR to work safely, there needs to be a lot of extra components on the circuit board/female connector side, which there simply isn't enough space for on an f2m extension cable.
As for why USB-C cables are so short, it's simply a matter of physics, carrying high speed data over larger distances would result in higher losses and requires thicker conductors and more shielding, which is why you don't see USB4 Gen3 cables over 1 meter unless they are optical, and longer "charging cables" are only rated at USB 2.0 speeds, because more often than not they don't even have the USB 3.x data pins on their connector.
You are a brilliant woman of many talents, Margot Robbie!
That's esteemed Academy Award nominated character actress Margot Robbie to you!
Also, thank you.
You're such a joker
I would say more like a Harley Quinn.
I have this cable: https://www.spigen.com/products/arcwire-usb-c-to-usb-c-cable-pb2202
It's 2 meters long, 240 watts and supports Thunderbolt 4/USB 4 (40 gbps).
I couldn't test the 240 watts charging as I don't have any device pulling more than 100 watts, but the Thunderbolt 4 part definitely works.
Apple sells a 3 meter Thunderbolt 4 cable (albeit limited to 100 watts of power) that isn't optical either (I think there's some special circuitry in the plugs though).
You're right. Those are active cables which I forgot to mention earlier that have special circuits that amplify signals, but are also a lot more expensive as a result.
Will I get banned if I don't call this person Margot Robbie, because they claim to identify as a famous Hollywood actress?
I believe that Margo Robbie identifies as esteemed Academy Award nominated character actress/esteemed Academy Award nominated character actresses.
$90 for a cable and it’s not even braided is wild to me.
I prefer not braided. Both for cables and hair. More of a ponytail kinda guy myself.
Braiding doesn't really increase the cable quality per se though..?
It's $90 because it has fairly thick wiring and as Margot said is likely an active cable (with a chip in the plug). It's actually fairly cheap considering the feature set.
A shielded braid reduce the noise on the data lines and gives a better signal integrity. So it doesn't increase the quality of the material, but increase the signal to noise ratio (SNR), which is very important for data transmission.
Braided cables are just higher quality imo because they can’t tangle easily and take a lot of effort to bend.
I don't seem to be able to upvote this twice.
You could always buy more copies of "Barbie" on Blu-ray for Christmas.
Just saying.
Absolute gold 🤣
It's amazing for a "standard" that there can be so many non-standard ways to do it. Your explanation is great and just reminded me that cable tester tools are a really good idea to have at home. There was one in Kickstarter earlier this year, I think, that was a really smart idea. I don't recall what it was nqmed though. Maybe you have heard of it? I'll see if I can find it.
Regardless, there are some devices that really need a specific type of usb-c cable to function properly and/or not burn the circuitry. (i.e. Nintendo Switch, the original release model (though, they may have fixed it in later hardware revisions))
Edit: Found it! That cable tester that I was referring to was called the BLE CaberQU. I think it is a really neat idea.
Nice! I’ve wanted a tool exactly like that many times. I’ll back it and see.
The closest I could find before were essentially pin to pin continuity checkers, which are useful for telling if a cable is PD only, 2.0 vs 3.x, or has a line break, but most of those can be eyeballed, otherwise metered. So these just checkers just add precision and speed to something you already know how to do.
The runner ups were the (now ubiquitous) inline inductive energy trackers, because they can tell you a bit more about the gauge of the wires in the cable which can be important, especially high amperage 5v like pi 4.B
But to test quality of shielding for high rate data transfer, DP and PCI-E tunneling, etc., the only option was manually user testing with adequately powerful devices.
I'm glad someone is smart cause I sure ain't
Nice explanation, thanks!
It's a great explanation. However you have some pretty egregious use of commas that made it a lot more confusing. I had to read it over multiple times to fully understand.
It may seem like nitpicking but these subtle issues end up making it harder to comprehend and overall results in more time and effort for everyone you're trying to inform.
You know you explained a topic pretty damn accurately when the Stranger On The Internet can only use the good ol' "too many commas'" argument to bring you down.
Why are you assuming he's trying to bring the guy down? He could genuinely have a problem parsing the comment and you're here just dismissing his experience.
I didn't know that assuming your experience applies to everyone is generally accepted in Lemmy nowadays, considering the voting ratio.
I don't agree with his point that there are too many commas, but implying that his experience is faked and his comment is made due to malicious intent is just particularly stupid.
My comment was intended more to praise OP than to deride the person who replied. It was probably worded badly. I guess I should have said something more along the lines of 'You know your argument is good when the only fault to be found by internet strangers is too many commas'.
Yeah, that actually conveyed your meaning much better than your original wording. I understand what you meant now. That means my comment was way too aggressive for what you wanted to convey, so I will apologize.
What the fuck did you just fucking say about me, you little shit? Ill have you know I graduated top of my class in the Navy Seals, and Ive been involved in numerous secret...
Oh. Oh wait. I think the shock of what I just read reverted me to default internet discussion... Was that just a polite exchange where we saw the others point of view, then both admitted we could have done better? Nice!
Didn't have any issues reading it. Come off it
Some languages have a very different usage of comas. Maybe OP's mother tongue is one of those
