Um...so this is still optical cable, yes?

[Dos_Box]

I'm a bit baffled by this. Special lasers, ok, got it, but not much mention of the actual cable, which I suspect is just going to be xxth gen fibre?

i suspect its poor wording you cant go ftl but you can send more data per time unit or more data with thinner strands so you can get more data in a given cable diamater

[djm968]

I don't think they have actually got to the point where they are sending data, they have just managed to find a way of modulating light emitted in the terahertz range using acoustic waves, but this will definitively require a new fibre cable specification and wireless equipment. https://arxiv.org/ftp/arxiv/papers/1506/1506.03175.pdf Edited February 12, 2020 by djm968

It's science reporting in a newspaper - so your base expectation should be that it's 100% incorrect

so your base expectation should be that it's 95% incorrect

but you've no idea which 5% may be on track.

Current – very fast – ethernet connections work at 100 megabits a second, a thousand times less quick

 

Um, no.

I thought 00:35 was an ethernet cable poking into a garden fence till I looked properly

 

 

Eh ?!?

Um, no.

 

That's what I thought!

 

How to make the headline look good - base the comparison on very quick 100mb ethernet, not 1gb ethernet!

It's science reporting in a newspaper - so your base expectation should be that it's 100% incorrect

 

And that it causes cancer.

The study saw researchers make a breakthrough in the control of terahertz quantum cascade lasers, which they say could be used to transmit data wirelessly over short distances at a speed of 100 gigabits. Current ethernet connections work at 100 megabits a second, a thousand times less quick.

 

short distances is a small phrase doing a lot of work right there

 

Ethernet hasn't been at 100mbps as standard for about a decade

 

If they've only just done the proof-of-concept work, it's about 10-15 years away at least, by which time 10Gbps may well be the common standard, and then this is far less impressive

 

In short: tabloid reporting!

[bald_pig]

It's the usual guff that tabloids pick up, I suspect that there may well be a thunderf00t video tearing it to shreds soon.

Newspapers just reprint the press releases from universities really
