Researchers develop optical fibre capable of over 1 petabit per second

Published

on

A coupler created by Macquarie University in Australia, combined with a fibre fabricated by Hokkaido University and equipment maker Fujikura, and a transmission system developed by the National Institute of Information and Communications Technology in Japan, has led to transmission speeds in excess of 1 petabit.

The new four-core, three-mode fibre was touted as being the same width as existing standard fibre, but was capable of 12 times the data speed. Macquarie University said the fibre was less prone to damage due to its narrower diameter, and could be used with existing equipment.

“The world’s insatiable demand for data means that we are approaching a ‘capacity crunch’ and need to find new ways to transport ever-larger volumes,” said Dr Simon Gross of the Macquarie Photonics Research Centre.

“This technology promises a solution to the bottleneck created by existing optical fibres. For the first time, we have created a realistic and useable-sized fibre which is resilient and can transport huge amounts of data.”

Uses of the fibre would be in backhaul networks, the university said, although it pointed out that the fibre’s capacity was “12 million times quicker than the fastest NBN connection”.

In September, NBN announced that it had doubled the capacity on its fibre-optic transit network to 19.2Tbps per fibre link.

The upgraded capacity kicked off in Sydney between Eastern Creek and Asquith, with the 3,600km route between Darwin and Brisbane to follow in December — to support growth on the Sky Muster satellite service — and will then be switched on progressively across the nation.

“The capacity upgrade has been made possible with the successful installation of new optical transmission technology — from network equipment maker Coriant’s CloudWave Optics — that supports per-wavelength transmission rates of 200 gigabits per second (Gbps) on optical transport backbone networks,” NBN explained.

Earlier in the year, Japanese giant NEC teamed up with Google to work out how to use artificial intelligence to boost the spectral efficiency across the FASTER subsea cable system to 6 bits per second per hertz for a capacity of more than 26 terabits per second.

Galaxy Z Fold 4 Under-Display Camera May Get A Stealthy Makeover

Published

on

According to a tweet from the account @SamsungRydah, which was first spied by SamMobile and has since been removed by Twitter based on a copyright claim (seemingly lending credibility to the leak), the Galaxy Z Fold 4 will rectify the poor invisibility of the UDC. The model will reportedly use a different arrangement of pixels to make it denser, providing a 132ppi circle, up from the Galaxy Z Fold 3 model’s measly 94ppi. The result is that the hole will hopefully be less visible, and text should be less distorted in that area. Unfortunately, it’s not completely invisible, at least not based on the leaked slide.

What isn’t clear, however, is whether Samsung is also upgrading the camera sensor itself to something more than just 4MP. Increasing the sensor’s own pixel count could help offset whatever side effects the UDC panel might have in terms of quality. While the Galaxy Z Fold 3 foldable’s internal camera was moderately usable for video calls, it just didn’t sit well with buyers considering how much they’d paid for the premium phone.

An upgraded internal camera would be in line with upgrades to the other cameras expected for the Galaxy Z Fold 4. These include a 50MP main sensor and a 10MP telephoto with 3x optical zoom. These are moderate upgrades, of course, but Samsung seems to be taking a page from Apple’s book here by improving quality through software and other minor tweaks rather than going all out on what would be a bulky sensor that wouldn’t fit the Galaxy Z Fold 4 model’s slim profile.

Today’s Wordle Answer #416 – August 9, 2022 Solution And Hints

Published

on

The answer to today’s Wordle puzzle (#416 – August 9, 2022) is patty. Its meaning varies across cultural contexts — to the British, it’s a small pie or pastry; to North Americans, it’s a small, round, and flat chocolate-covered peppermint sweet. More generally to Americans, it’s a small flat cake of minced or finely chopped food, especially meat (via Merriam-Webster). To Mr. Krabs of SpongeBob, it’s a veggie burger (and a moneymaker). Seeing as the word patty has roots in the French word “pat,e” which means dough, Mr. Krabs obviously knew what he was doing. 

We solved the puzzle in four tries today, just like yesterday and the day before. We began guessing with the word roate, which is an uncommon but excellent first guess (even the WordleBot thought so). After following up with fluid, we hit a lucky strike with catty — only one letter short of the correct answer.

The Reason Ford Won’t Build A Mustang GT500 Convertible

Published

on

Ford won’t be making a convertible Mustang GT500 because… it’s too powerful.

Hau Thai-Tang, Ford’s chief product platform, and operations officer confirmed the S550 platform on which the Mustang was built had reached “the top end of the capabilities” (via Muscle Cars & Trucks).

Dave Pericack, former Director Enterprise Product Line Management — Ford Icons, backs up those comments even more bluntly. “The real reason” Ford isn’t making a convertible model is because, by removing the roof, the car would lose all its structure and stiffness in the chassis and body. The power of the GT500 is simply too much for a convertible car to handle.

The only way it could make a convertible model would be to “spend a lot of money in exotic material” to compensate for the loss of the roof and the structural integrity it provides (via Ford Authority). Ford is not prepared to do that, considering the S550 platform is nearing the end of its road. The S650 platform — the seventh generation of Ford Mustangs — is on its way and will, in all likelihood, be the last Mustang with an internal combustion engine.

Fear not Ford faithful. The Blue Oval is already looking to the future and has already built a 900hp electric Mustang to show the world that an EV can also be a muscle car.
