I agree. HiFi forums are the absolute worst..
Me, getting a laptop specifically with 4 USB-A ports, and Ethernet port built in because I was fed up with Mac… Yeah, I'm not the average user, LOL. But I'd love to see a video on powerline adapters for internet anywhere in the house. I've been having issues with mine, but in theory, they're a useful thing.
One of the ISPs in my area keeps advertising fibre-optic internet with 500Mbps to even up to 800Mbps, where most of the cheaper non fibre stuff gets up to 100Mbps on a good day. We talked about some of the differences in a networks class I took and it was interesting to look at, but usually in IT, the consensus is that optics is faster. Unless it's optical disks…
Considering the "historical perspective" is very important. Looking back in history, remember that Bill Gates said, many years ago, that 640KB was "more than enough memory" for a personal computer.
Now EU decided to standardized the usb3 for all low voltage device also the brick socket
"What we in the industry call…itty bitty"
That's not true. We call it teeny weeny
6:45 I'm finishing my optics degree currently and have always heard "modal dispersion" used. There are other forms of dispersion and noise, of course, but that seems to be the most standard name for this particular form.
We could totally send power over optical without copper wires. Just make the light so intense, like a kilowatt laser, it can be converted into heat on the other end, which can be converted in to electricity. I’m only joking, but us humans LOVE inefficient things like wireless charging.
Another GREAT webcast: great simple ground loop explanation. I'm stealling UniLink 🙂 love the scarcasm as well.
POC power over cat just doesn't sound good
You can run several wavelenghts (colors) of light through single fiber to replace several copper wires. This is commonly used.
I like how you mentioned the Fiber USB cable and I remember seeing a video recently about that exact cable's successor that he used just recently that was otherwise secret. I can't recall what video it was but they're still going and improving fiber cables. Maybe one day it'll be more commonplace after all.
My company has used some XRF equipment that still puts usb mini on everything. We asked them why they are using an obsolete connector and they said they didn't think people who upgraded their devices would want to run a new cable to it. That kind of stupidity is why we still have to deal with so many cable connector types.
phone without audio jack? WoW.
Love it when you get all sassy
I can think of a reason to switch to optics instead of copper… material supply
Simple solution to the angle problem, start with furthest angle to begin with, ie a corner of the tube
Could cable durability be part of the reason why thunder bolt sticked with copper? I don't know about that plastic fiber, but the regular fiber would not have a good time being tossed around in a backpack
Please explain how optical amplifiers work!!!
iHAiUAHIAiUAHUAhAUAuihAIuhAiuh… Totally got me with the early THE END!
Having dealt with end users professionally for the past 10 years (and semi-professionally even longer than that), I feel safe in saying that most basic users would just be confused by having a single, unified cable standard for every application. Having a distinct, visual difference in cables – and more specifically, in their connectors – makes it easier for people to identify them once they are able to associate what each does. Think about how difficult it is already to identify what USB cable goes to what device, unless you had the foresight to label them at the ends or can visually trace them back. Where as for connectors like HDMI, VGA, RGB, and so on, you can just glance at the connector and immediately have at least a vague idea what it's going to.
Older video, but isn't copper just all around cheaper? Why need an LED when you can just blast the electricity down a wire?
I swapped to an optical HDMI cable for my 30ft HDMI needs, but it was more expensive than the other long HDMI Cable I had…
