Danish scientists achieve 1.84 Petabit per second data transfer over single fiber optics cable

[Redaktion]

The entire Internet's bandwidth almost twice over was squeezed through a single fiber optics cable with the aid of a revolutionary photonic chip that splits a laser beam into different colors.

Computer has 1Gbit, 100 Mbit and 480 Mbit USB 2, WiFi 867Mbit but 4G internet not getting even one MB with ping 1000 milliseconds.

A longstanding and rhetorical question - when the hell will the IT industry switch to optical HDMI and DP cables? Yes, it's time for USB. Consumers constantly struggle with finding high-quality cables of the required distance (try, for example, to find a high-quality 15m HDMI 2.1 cable for a projector, even for 2.0b this is a problem), because high-quality copper cables are many times more expensive than optical cables at the right distances and have long become obsolete. The world must already switch to optics.

On the other hand, the speed of communication protocols with monitors and peripherals is severely limited by the speed of RAM. And this shameful part of all PCs over the past 13 years has grown only 2-3 times in bandwidth (from 20-25 GB / s to 40-70). And it should have been 10 times higher - at least 200 GB / s, and for the most ordinary computer and laptop on some i3, not to mention I5 and higher. DDR memory has completely outlived itself as a technology, but the IT industry, which is entering a complete, fundamental technological impasse, does not have solutions and answers to this that meet the requirements of time and progress.

Somewhere out there, in the quiet of laboratories, egghead-corypheus scientists show super results, but in an ordinary laptop there is still a 1Gb/s link, instead of at least 5 Gb/s, and most routers are the same for sale, miserable, outdated.
The same scientists promised us over the past 15 years 100500 (I lost count a long time ago, according to this lie from small startups, which, having mastered grants with an appetite, eventually disappear somewhere) super-improvements of lithium-ion batteries, but we still use smartphones with the need to charge in 1-2 days . Instead of once a week or month...

Yes, it is nuts. Just put optical fiber and copper in the same wire so it can do power delivery or legacy modes if needed. If it's expensive, well, any DP/HDMI 3.0 or USB5 cable was likely to be expensive and the customers will not care if they actually need the speed.

USB4 Version 2.0 staves off the inevitable by doing 120 Gb/s in one direction, and I don't see why they can't get that to 160 Gb/s. After that, hopefully their bag of tricks runs out.

Capitalists are not interested in rapid progress, because it limits profits. This comes into conflict with the interests of civilization, but humanity has not yet come up with another more effective economic and social structure of society (which takes into account the natural human vices of its ordinary members), except for the chimera with communism (which in practice always turns into a normal one by bastards). feudal-slave-owning system with false slogans and ideology), etc. nonsense. Unfortunately, capitalism, in its natural form with perfect competition and respect for the rights between the participants, also does not exist on the planet - but there is imperialism (i.e. the dominance of large trans-national companies that own huge layers of intellectual property in the mode of patent trolls). The problem is in the patent system. It must be changed, reducing the ability of old and very large companies to hold rights for a long time. This should be significantly limited in favor of start-ups, but it is necessary to somehow combat the widespread use of pseudo-scientists and pseudo-science in science, which is increasingly optimized for drinking grants, and not for the efficient use of investors' resources. The more intellectual the activity, the more ground for abuse and fraud - the audit is more and more difficult ...
