I recently visited friend at his lab. I cannot say much but they work on patent for something he calls “pantone fiber”. Basically within one cable they are able to squeeze about 16,000 different shades of R/G/B “working” next to each other. When I grasp the idea it blew my mind - he looked at me and smiled saying - “yeah about 10,000 times faster than current fiber”. He said two things tho - one state of tech is not ready for such speeds and latency - unlesn you have 16K def TV. Second he said they wont release it until much more cable has been layed out. So that of course they can restart relaying new cable again and make more $ ;)
- akg_67 8y agoDid your friend say 10,000 times faster or 10,000 times bandwidth? By using different color simultaneously , you can stuff more data but I can’t imagine it becoming faster than speed of light it already travels at.
- eastdakota 8y agoFor a bit, yes. For N bits, more bandwidth means more effective speed.
- swombat 8y agoWell, no, not unless you define speed as “bandwidth”. If it takes 1ms for the 1 bit to get to the other side, it’s still going to take 1ms for N bits to get to the other side, even N-multiplexed. It’s the bandwidth that’s improved with multiplexing.
- stingraycharles 8y agoWhile you're technically correct, isn't it pretty much an accepted fact that when people refer to the "speed" of internet, they are actually talking about bandwidth? E.g. "how fast is your internet", etc. It's of little value to the end user to know how fast a bit travels, all they care about is how fast they can download.
- 00deadbeef 8y agoI'm sure he knows that and is just being pedantic for the sake of it
- swombat 8y agoOn HN? Never!
- robkop 8y agoIsn't this just an advancement on wavelength division multiplexing? https://en.m.wikipedia.org/wiki/Wavelength-division_multiplexing https://en.m.wikipedia.org/wiki/Wavelength-division_multiple...
