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.

How To Easily Find Electric Car Charging Points Near You

Published

on

Electric cars are the future of the automobile industry, with virtually every manufacturer already building electric vehicles (EVs). Many manufacturers have even gone a step further, committing to an all-EV lineup in the near future.

Despite how quickly the industry is pivoting to EVs, range anxiety is still the biggest issue slowing down faster adoption. For example, one study showed that 1 in 5 California plug-in EV owners end up going back to gasoline-powered vehicles over range anxiety and the difficulty involved in quickly charging an EV.

If you’re a current EV owner or considering becoming one, knowing how to easily find all available EV charging points near you is an important step in easing range anxiety and enjoying your EV. Fortunately, there’s a couple of easy ways to do it.

Use Google Maps In Your Vehicle

One of the easiest ways to find nearby EV charging stations is by using Google Maps.

Google’s in-vehicle version of Google Maps offers a number of features designed to reduce range anxiety. For longer trips, the software can help plan your route according to available charging stations, and even make recommendations on when and where you should stop for a charge.

“Now when you enter a destination that requires two or more recharge stops, algorithms in Maps will search and filter through tens to thousands of public charging stations to find the most efficient route — all in less than 10 seconds,” writes Alex Donaldson, Product Manager, Google Maps. “You can see how long each charge will take and your updated total trip time, so your final ETA will never again be a mystery.”

Unfortunately, at the time of writing, the list of EVs with Google’s software built-in is still relatively short but includes the Polestar 2 and Volvo XC40 Recharge.

Use Google Maps On Your Phone

If you don’t own one of the vehicles that have Google’s mapping software built-in, you can still use Maps on your phone to access many of the same features.

Beginning in 2019, Google started adding EV charging information into Maps, and users can now find charging locations, as well as important information about each location. For example, you can find out what kind of charging ports are supported, what charging speeds are offered, and how many stations are currently available.

“Simply search for ‘ev charging stations’ to see up to date information from networks like Chargemaster, EVgo, SemaConnect and soon, Chargepoint,” writes Donaldson. “You’ll then see how many ports are currently available, along with other helpful details, like the business where the station is located, port types and charging speeds. You’ll also see information about the station from other drivers, including photos, ratings, reviews and questions.”

Use Apple Maps

Similarly, Apple Maps provides an easy way to find nearby charging stations. Beginning with iOS 14, Apple added the ability to plan your route according to your vehicle and compatible charging locations.

“Electric vehicle routing adds charging stops along a planned route based on current vehicle charge and charger types,” notes Apple in the iOS 14 press release.

Thanks to Google and Apple, overcoming range anxiety has never been easier. All the information you need to plan your trip or go about your day’s activity is right at your fingertips.

Apple CarPlay on a Tesla made possible with this hack

Published

on

Tesla might be most controversial for its misunderstood and misused self-driving features, but for a certain number of car owners, its biggest is simpler. Tesla still refuses to play ball with Apple and add support for CarPlay or even Apple Music, no matter how loud its customers clamor for it. It doesn’t seem that things will be changing soon, so a developer tried to take matters into his own hands with relative success.

Pi Power

Although initially intended to be more of an educational tool, the Raspberry Pi has become the darling of makers, hackers, and developers who need an affordable yet almost complete computer that’s the size of a credit card (but way, way thicker). It can run a variety of operating systems, including even Windows, and with some add-ons, it can do almost everything that a regular PC can and more.

That’s what Polish developer Michał Gapiński did when he set out to solve one of the biggest pain points about Tesla: its lack of support for Apple CarPlay or Music.

He installed an Android-based ROM on the single-board computer (SBC) and turned it into a Wi-Fi access point. Connecting the Tesla’s browser to the Raspberry Pi gives access to CarPlay and all its features, making it look like Apple’s in-vehicle infotainment system is actually running on Tesla’s dash. It even works with steering wheel controls

Tesla and Apple

For reasons still unknown, Tesla refuses to support even Apple Music on its cars. Both companies want full control of the software running inside vehicles, so it’s not surprising that their ideologies clash. That said, almost all carmakers today support Apple CarPlay or even just streaming from Apple Music, leaving Tesla as the odd one out.

Gapiński’s workaround is hardly ideal, but the lack of any official solution leaves people with very few options. The developer is working on refining the system, but it will always be a hack in many other ways. Gapiński promises to make it available to the public once it reaches a more decent state.
