AT&T Breaks Major Fibre Speed Barrier
techradar.pro, June 13th, 2022
AT&T says 20Gbps services possible in the future

US broadband operator AT&T has become the first in the industry to achieve a 20Gbps symmetrical speed on a production fibre network, claiming the milestone could mean even faster speeds for consumers and businesses in the near future.

The company achieved the transmission rate on 25GS-PON in its broadband lab in Austin, Texas and says the technology can work with its existing fibre network.

The company achieved 10Gbps in lab tests earlier this year and has a commercial 5Gbps 'Hyper Gig' broadband offering in the US.


Chip-level design breakthrough provides bandwidth boost for supercomputers and artificial intelligence (AI) applications

IT vendors typically race to deliver incremental improvements to existing product lines, but occasionally a truly disruptive technology comes along. One of those disruptive technologies, which is beginning to find its way into enterprise data centers, is High-Bandwidth Memory (HBM).

HBM is significantly faster than incumbent memory chip technologies, uses less power and takes up less space. It is becoming particularly popular for resource-intensive applications such as high-performance computing (HPC) and artificial intelligence (AI).


Team Blue's new lithography seems to be yielding impressive results

Intel has given us our first proper look at its 14th-generation desktop and mobile CPUs, codenamed 'Meteor Lake', which are due to launch in 2023. These will be the first processors to utilize the new 'Intel 4' process node, which is replacing the Intel 7 design used in the company's current CPUs.

Intel 4 is a 7nm process technology, while Intel 7 was 10nm (yes, we agree that the naming convention is silly). The exciting part is that Intel 4 will use a new type of processor lithography called 'advanced extreme ultraviolet' lithography, or EUV for short. This replaces the conventional deep-UV immersion lithography used in current processor production.


Star Trek's glowing circuit boards may not be so crazy

Science fiction is littered with fantastic visions of computing. One of the more pervasive is the idea that one day computers will run on light. After all, what's faster than the speed of light?

But it turns out Star Trek's glowing circuit boards might be closer to reality than you think, Ayar Labs CTO Mark Wade tells The Register. While fiber optic communications have been around for half a century, we've only recently started applying the technology at the board level. Despite this, Wade expects, within the next decade, optical waveguides will begin supplanting the copper traces on PCBs as shipments of optical I/O products take off.
