The Spanish government is introducing a porn passport to help porn platforms verify users' ages. Slashdot reader fjo3 shares a report from Politico: Officially (and drily) called the Digital Wallet Beta (Cartera Digital Beta), the app Madrid unveiled on Monday would allow internet platforms to check whether a prospective smut-watcher is over 18. Porn-viewers will be asked to use the app to verify their age. Once verified, they'll receive 30 generated "porn credits" with a one-month validity granting them access to adult content. Enthusiasts will be able to request extra credits.

While the tool has been criticized for its complexity, the government says the credit-based model is more privacy-friendly, ensuring that users' online activities are not easily traceable. The system will be available by the end of the summer. It will be voluntary, as online platforms can rely on other age-verification methods to screen out inappropriate viewers. It heralds an EU law going into force in October 2027, which will require websites to stop minors from accessing porn. Eventually, Madrid's porn passport is likely to be replaced by the EU's very own digital identity system (eIDAS2) -- a so-called wallet app allowing people to access a smorgasbord of public and private services across the whole bloc.

Ahead of its one-year anniversary, Meta CEO Mark Zuckerberg announced that Threads has reached more than 175 million monthly active users. The Verge reports: Back when it arrived in the App Store on July 5th, 2023, Musk was taking a wrecking ball to the service formerly called Twitter and goading Zuckerberg into a literal cage match that never happened. A year later, Threads is still growing at a steady clip -- albeit not as quickly as its huge launch -- while Musk hasn't shared comparable metrics for X since he took over.

As with any social network, and especially for Threads, monthly users only tell part of the growth story. It's telling that, unlike Facebook, WhatsApp, and Instagram, Meta hasn't shared daily user numbers yet. That omission suggests Threads is still getting a lot of flyby traffic from people who have yet to become regular users. I've heard from Meta employees in recent months that much of the app's growth is still coming from it being promoted inside Instagram. Both apps share the same account system, which isn't expected to change.

The FTC has issued warnings to several tech firms, including PC manufacturers ASRock, Gigabyte, and Zotac, regarding potential violations of the Magnuson-Moss Warranty Act. The agency expressed concerns that the companies' warranty and repair policies may be infringing on consumer rights. PCWorld adds: While the specific concerns vary by company, the FTC reminded the three companies that they can't, for example, place stickers on a laptop that caution consumers that opening or repairing the laptop violates warranty policies.

Neither can they state or imply that their products can only be repaired via an authorized service from the company. In the letter sent to Gigabyte (PDF), the FTC said that its staff is "concerned" by the Gigabyte written warranty, which includes the phrase: "If the manufacturing sticker inside the product was removed or damaged, it would no longer be covered by the warranty."

Tech companies scouring the country for electricity supplies have zeroed in on a key target: America's nuclear-power plants. From a report: The owners of roughly a third of U.S. nuclear-power plants are in talks with tech companies to provide electricity to new data centers needed to meet the demands of an artificial-intelligence boom. Among them, Amazon Web Services is nearing a deal for electricity supplied directly from a nuclear plant on the East Coast with Constellation Energy, the largest owner of U.S. nuclear-power plants, according to people familiar with the matter. In a separate deal in March, the Amazon subsidiary purchased a nuclear-powered data center in Pennsylvania for $650 million.

The discussions have the potential to remove stable power generation from the grid while reliability concerns are rising across much of the U.S. and new kinds of electricity users -- including AI, manufacturing and transportation -- are significantly increasing the demand for electricity in pockets of the country. Nuclear-powered data centers would match the grid's highest-reliability workhorse with a wealthy customer that wants 24-7 carbon-free power, likely speeding the addition of data centers needed in the global AI race. But instead of adding new green energy to meet their soaring power needs, tech companies would be effectively diverting existing electricity resources. That could raise prices for other customers and hold back emission-cutting goals.

Ars Technica's Eric Berger writes: On the day before Christmas last year, a Falcon 9 rocket launched from California and put two spy satellites into low-Earth orbit for the armed forces of Germany, which are collectively called the Bundeswehr. Initially, the mission appeared successful. The German satellite manufacturer, OHB, declared that the two satellites were "safely in orbit." The addition of the two SARah satellites completed a next-generation constellation of three reconnaissance satellites, the company said. However, six months later, the two satellites have yet to become operational. According to the German publication Der Spiegel, the antennas on the satellites cannot be unfolded. Engineers with OHB have tried to resolve the issue by resetting the flight software, performing maneuvers to vibrate or shake the antennas loose, and more to no avail. As a result, last week, German lawmakers were informed that the two new satellites will probably not go into operation as planned.

The three-satellite constellation known as SARah -- the SAR is a reference to the synthetic aperture radar capability of the satellites -- was ordered in 2013 at a cost of $800 million. The first of the three satellites, SARah 1, launched in June 2022 on a Falcon 9 rocket. This satellite was built by Airbus in southern Germany, and it has since gone into operation without any problems. The two smaller satellites built by OHB, flying with passive synthetic aperture radar reflectors, were intended to complement the SARah 1 satellite, which carries an active phased-array radar antenna. [...] According to the Der Spiegel report, the Bundeswehr says the two SARah satellites built by OHB remain the property of the German company and would only be turned over to the military once they were operational. As a result, the military says OHB will be responsible for building two replacement satellites. Shockingly, the German publication says that its sources indicated OBH did not fully test the functionality and deployment of the satellite antennas on the ground. This could not be confirmed.

Longtime Slashdot reader fahrbot-bot shares a report from CNN, written by Olesya Dmitracova: Nyobolt, based in Cambridge, has developed a new 35kWh lithium-ion battery that was charged from 10% to 80% in just over four and a half minutes in its first live demonstration last week. [...] Nyobolt's technology builds on a decade of research led by University of Cambridge battery scientist Clare Grey and Cambridge-educated Shivareddy, the company said. Key to its batteries' ability to be charged super-fast without a big impact on their longevity is a design that means they generate less heat. It also makes them safer as overheating can cause a lithium-ion battery to catch fire and explode. In addition, the materials used to make the batteries' anodes allow for a faster transfer of electrons. Nyobolt is currently in talks to sell its batteries to eight electric car manufacturers. At 35 kWh, the battery is much smaller than the 85 kWh in a more typical American electric vehicle (EV). Yet the technology may be used in larger battery packs in the future.

Independent testing of Nyobolt's batteries by what it called a leading global manufacturer found that they can achieve over 4,000 fast-charge cycles, equivalent to 600,000 miles (965,600 kilometers), while retaining more than 80% of capacity, Nyobolt said in its Friday statement. William Kephart, an e-mobility specialist at consultancy P3 Group and a former engineer, said EV batteries of the kind Nyobolt has developed could "theoretically" be charged as fast as the firm is promising, but the challenge was manufacturing such batteries on an industrial scale. A crucial chemical element in Nyobolt's batteries is niobium but, as Kephart pointed out, last year only an estimated 83,000 tons (94,500 tons) was mined worldwide. Compare that with graphite, commonly used as anode material in lithium-ion batteries: an estimated 1.6 million tons (1.8 million tons) was produced in 2023. In addition, there are currently "a lot of unknowns" with the niobium battery technology, he told CNN. "The industry will work it out (but) it's not seen by the industry as a scalable technology just yet," he added.

Brazil's national data protection authority ruled on Tuesday that Meta must stop using data originating in the country to train its artificial intelligence models. The Associated Press reports: Meta's updated privacy policy enables the company to feed people's public posts into its AI systems. That practice will not be permitted in Brazil, however. The decision stems from "the imminent risk of serious and irreparable or difficult-to-repair damage to the fundamental rights of the affected data subjects," the agency said in the nation's official gazette. [...] Hye Jung Han, a Brazil-based researcher for the rights group, said in an email Tuesday that the regulator's action "helps to protect children from worrying that their personal data, shared with friends and family on Meta's platforms, might be used to inflict harm back on them in ways that are impossible to anticipate or guard against."

But the decision regarding Meta will "very likely" encourage other companies to refrain from being transparent in the use of data in the future, said Ronaldo Lemos, of the Institute of Technology and Society of Rio de Janeiro, a think-tank. "Meta was severely punished for being the only one among the Big Tech companies to clearly and in advance notify in its privacy policy that it would use data from its platforms to train artificial intelligence," he said. Compliance must be demonstrated by the company within five working days from the notification of the decision, and the agency established a daily fine of 50,000 reais ($8,820) for failure to do so. In a statement, Meta said the company is "disappointed" by the decision and insists its method "complies with privacy laws and regulations in Brazil."

"This is a step backwards for innovation, competition in AI development and further delays bringing the benefits of AI to people in Brazil," a spokesperson for the company added.

An anonymous reader quotes a report from the Financial Times: Google's greenhouse gas emissions have surged 48 percent in the past five years due to the expansion of its data centers that underpin artificial intelligence systems, leaving its commitment to get to "net zero" by 2030 in doubt. The Silicon Valley company's pollution amounted to 14.3 million tons of carbon equivalent in 2023, a 48 percent increase from its 2019 baseline and a 13 percent rise since last year, Google said in its annual environmental report on Tuesday. Google said the jump highlighted "the challenge of reducing emissions" at the same time as it invests in the build-out of large language models and their associated applications and infrastructure, admitting that "the future environmental impact of AI" was "complex and difficult to predict."

Chief sustainability officer Kate Brandt said the company remained committed to the 2030 target but stressed the "extremely ambitious" nature of the goal. "We do still expect our emissions to continue to rise before dropping towards our goal," said Brandt. She added that Google was "working very hard" on reducing its emissions, including by signing deals for clean energy. There was also a "tremendous opportunity for climate solutions that are enabled by AI," said Brandt. [...] In Tuesday's report, Google said its 2023 energy-related emissions -- which come primarily from data center electricity consumption -- rose 37 percent year on year, and overall represented a quarter of its total greenhouse gas emissions. Google's supply chain emissions -- its largest chunk, representing 75 percent of its total emissions -- also rose 8 percent. Google said they would "continue to rise in the near term" as a result in part of the build-out of the infrastructure needed to run AI systems.

Google has pledged to achieve net zero across its direct and indirect greenhouse gas emissions by 2030, and to run on carbon-free energy during every hour of every day within each grid it operates by the same date. However, the company warned in Tuesday's report that the "termination" of some clean energy projects during 2023 had pushed down the amount of renewables it had access to. Meanwhile, the company's data centre electricity consumption had "outpaced" Google's ability to bring more clean power projects online in the US and Asia-Pacific regions. Google's data centre electricity consumption increased 17 percent in 2023, and amounted to approximately 7-10 percent of global data center electricity consumption, the company estimated.Its data centers also consumed 17 percent more water in 2023 than during the previous year, Google said.

Longtime Slashdot reader regoli shares an obituary from the Wall Street Journal: When Alan Ashton was a computer-science professor at Brigham Young University in the mid-1970s, the director of the school's marching band knocked on his door and said he wanted to use a computer to choreograph the band's halftime shows. Ashton was easily persuaded; he was a trumpet player whose Ph.D. dissertation at the University of Utah was "Electronics, music and computers." Bruce Bastian, the graduate student who was working as BYU's marching-band director, turned out to be a quick learner. "He was very conscientious, very thorough," Ashton said in an interview, "and just absolutely brilliant." Within a few years, the two were at work on a program that would turn them into two of the richest people in the nation, founders of the company that made WordPerfect, the dominant word-processing software in the 1980s and early '90s and one of the first pieces of software many Americans bought when they brought home their first PCs.

But behind the hundreds of millions of dollars and blockbuster success, Bastian's personal life, he later said, was in "free fall." Between the time he and Ashton released what would later be known as WordPerfect to the public in 1980 and when they sold the company for $1.4 billion in 1994, Bastian told his wife, four sons and his Mormon community that he was gay and leaving both his marriage and the church. When he died, June 16, at the age of 76 from complications associated with pulmonary fibrosis, he had been living a different life: A longtime advocate for LGBTQ rights, Bastian was married to a man, and had found a way to maintain relationships with his family, who remained dedicated members of the church that rejected his sexual orientation. "I kind of have three parts of my life," he said in 2010 during one of several extensive interviews he gave to the Mormon Stories podcast, "the pre-WordPerfect life, the WordPerfect years, and now the LGBT years." Other publications remembering Bruce Bastian include: The New York Times, The Salt Lake Tribune, University of Utah, and Human Rights Campaign.

The Supreme Court has agreed to hear a challenge to a Texas law requiring age verification to access online pornography, which opponents argue violates the First Amendment by discouraging adults from viewing such material due to privacy concerns. A federal judge blocked the law citing its chilling effect on free speech, but a divided appeals court upheld it, emphasizing the government's interest in protecting minors; the case will now be reviewed by the Supreme Court. The Texas bill in question, HB 1181, was passed into law last June. The New York Times reports: The Supreme Court agreed on Tuesday to hear a challenge to a Texas law that seeks to limit minors' access to pornography on the internet by requiring age verification measures like the submission of government-issued IDs. A trade group, companies that produce sexual materials and a performer challenged the law, saying that it violates the First Amendment right of adults. The law does not allow companies to retain information their users submit. But the challengers said adults would be wary of supplying personal information for fear of identity theft, tracking and extortion. [...]

In urging the Supreme Court to leave the law in place while it considers whether to hear the case, Ken Paxton, Texas' attorney general, said pornography available on the internet is "orders of magnitude more graphic, violent and degrading than any so-called 'girlie' magazine of yesteryear." He added: "This statute does not prohibit the performance, production or even sale of pornography but, more modestly, simply requires the pornography industry that make billions of dollars from peddling smut to take commercially reasonable steps to ensure that those who access the material are adults. There is nothing unconstitutional about it."

An anonymous reader shares a report: ChromeOS Flex extends the lifespan of older hardware and contributes to reducing e-waste, making it an environmentally conscious choice. Unfortunately, recent developments hint at a potential end for ChromeOS Flex. As detailed in a June 12 blog post by Prajakta Gudadhe, senior director of engineering for ChromeOS, and Alexander Kuscher, senior director of product management for ChromeOS, Google's announcement about integrating ChromeOS with Android to enhance AI capabilities suggests that Flex might not be part of this future.

Google's plan, as detailed, suggests that ChromeOS Flex could be phased out, leaving its current users in a difficult position. The ChromiumOS community around ChromeOS Flex may attempt to adjust to these changes if Google open sources ChromeOS Flex, but this is not a guarantee. In the meantime, users may want to consider alternatives, such as various Linux distributions, to keep their older hardware functional.

Design startup Figma is temporarily disabling its "Make Design" AI feature that was said to be ripping off the designs of Apple's own Weather app. TechCrunch: The problem was first spotted by Andy Allen, the founder of NotBoring Software, which makes a suite of apps that includes a popular, skinnable Weather app and other utilities. He found by testing Figma's tool that it would repeatedly reproduce Apple's Weather app when used as a design aid. John Gruber, writing at DaringFireball: This is even more disgraceful than a human rip-off. Figma knows what they trained this thing on, and they know what it outputs. In the case of this utter, shameless, abject rip-off of Apple Weather, they're even copying Weather's semi-inscrutable (semi-scrutable?) daily temperature range bars.

"AI" didn't do this. Figma did this. And they're handing this feature to designers who trust Figma and are the ones who are going to be on the hook when they present a design that, unbeknownst to them, is a blatant rip-off of some existing app.

Digital audio broadcasting (DAB+) and internet radio have largely replaced traditional FM radio in Switzerland, with digital radio holding an 81% share of use in spring 2023. Due to the high costs of maintaining FM transmitters and declining financial resources, Switzerland plans to fully transition to digital radio by the end of 2026, phasing out FM broadcasting completely. From a report: DAB+ and the internet offer better quality and a larger program selection, are more energy and cost efficient, and can provide additional information in text and images, it said. To receive DAB+ requires a corresponding device or adapter, and new cars have been equipped with digital technology as standard for several years. In addition, the Federal Roads Office (FEDRO) will upgrade all tunnels on the national road network for digital radio reception by the end of the year and switch off FM transmitters.

FM was originally expected to be switched off throughout Switzerland by the end of 2024. The government extended FM licenses for the radio industry for the last time in October 2023 to the end of 2026, after which radio stations in Switzerland will no longer be able to broadcast via FM, only digitally. OFCOM announced at the time that the final extension would give the radio industry the flexibility to complete the transition process from analogue to digital radio.

An anonymous reader quotes a report from Ars Technica: Meta continues to hit walls with its heavily scrutinized plan to comply with the European Union's strict online competition law, the Digital Markets Act (DMA), by offering Facebook and Instagram subscriptions as an alternative for privacy-inclined users who want to opt out of ad targeting. Today, the European Commission (EC) announced preliminary findings that Meta's so-called "pay or consent" or "pay or OK" model -- which gives users a choice to either pay for access to its platforms or give consent to collect user data to target ads -- is not compliant with the DMA. According to the EC, Meta's advertising model violates the DMA in two ways. First, it "does not allow users to opt for a service that uses less of their personal data but is otherwise equivalent to the 'personalized ads-based service." And second, it "does not allow users to exercise their right to freely consent to the combination of their personal data," the press release said.

Now, Meta will have a chance to review the EC's evidence and defend its policy, with today's findings kicking off a process that will take months. The EC's investigation is expected to conclude next March. Thierry Breton, the commissioner for the internal market, said in the press release that the preliminary findings represent "another important step" to ensure Meta's full compliance with the DMA. "The DMA is there to give back to the users the power to decide how their data is used and ensure innovative companies can compete on equal footing with tech giants on data access," Breton said. A Meta spokesperson told Ars that Meta plans to fight the findings -- which could trigger fines up to 10 percent of the company's worldwide turnover, as well as fines up to 20 percent for repeat infringement if Meta loses. The EC agreed that more talks were needed, writing in the press release, "the Commission continues its constructive engagement with Meta to identify a satisfactory path towards effective compliance." Meta continues to claim that its "subscription for no ads" model was "endorsed" by the highest court in Europe, the Court of Justice of the European Union (CJEU), last year.

"Subscription for no ads follows the direction of the highest court in Europe and complies with the DMA," Meta's spokesperson said. "We look forward to further constructive dialogue with the European Commission to bring this investigation to a close."

Meta rolled out its ad-free subscription service option last November. "Depending on where you purchase it will cost $10.5/month on the web or $13.75/month on iOS and Android," said the company in a blog post. "Regardless of where you purchase, the subscription will apply to all linked Facebook and Instagram accounts in a user's Accounts Center. As is the case for many online subscriptions, the iOS and Android pricing take into account the fees that Apple and Google charge through respective purchasing policies."

A new study suggests at least 10% of scientific abstracts in 2024 were processed using large language models, researchers from the University of Tubingen and Northwestern University report. Analyzing 14 million PubMed abstracts from 2010-2024, the team identified an unprecedented surge in certain "style words" following LLMs' widespread adoption in late 2022.

Words like "delves" and "showcasing" saw a 25-fold and 9-fold increase respectively in 2024 abstracts compared to pre-LLM trends. Common terms such as "potential" and "findings" also spiked in usage. The researchers drew parallels to studies measuring COVID-19's impact through excess deaths, applying a similar methodology to detect "excess word usage" in scientific writing.

Apple's decision not to launch its own AI features in the EU is a "stunning declaration" of its anticompetitive behavior, European Commission Vice-President Margrethe Vestager said. From a report: About two weeks ago, Apple announced it will not launch its homegrown AI features in the EU, saying that interoperability required by the EU's Digital Markets Act (DMA) could hurt user privacy and security. A few days later, the Commission accused Apple's App Store of DMA breaches. Apple's move to roll back its AI plans in Europe is the most "stunning, open declaration that they know 100% that this is another way of disabling competition where they have a stronghold already," Vestager, the Commission's vice president for a Europe fit for the digital age and Commissioner for Competition, told a Forum Europa event.

The "short version of the DMA [Digital Markets Act]" is that to operate in Europe, companies have to be open for competition, said Vestager. The DMA foresees fines of up to 10% of annual revenue, which in Apple's case could be over $32.2 billion, based on its previous financial performance. For repeated infringements, that percentage could double.

In 1994, college student Jim Hall created FreeDOS (in response to Microsoft's plan to gradually phase out MS-DOS). After celebrating its 30th anniversary last week, Hill wrote a new article Saturday for OpenSource.net: "What I've learned about Open Source community over 30 years."

Lessons include "every Open Source project needs a website," but also "consider other ways to raise awareness about your Open Source software project." ("In the FreeDOS Project, we've found that posting videos to our YouTube channel is an excellent way to help people learn about FreeDOS... The more information you can share about your Open Source project, the more people will find it familiar and want to try it out.")

But the larger lesson is that "Open Source projects must be grounded in community." Without open doors for new ideas and ongoing development, even the most well-intentioned project becomes a stagnant echo chamber...

Maintain open lines of communication... This can take many forms, including an email list, discussion board, or some other discussion forum. Other forums where people can ask more general "Help me" questions are okay but try to keep all discussions about project development on your official discussion channel.
The last of its seven points stresses that "An Open Source project isn't really Open Source without source code that everyone can download, study, use, modify and share" (urging careful selection for your project's licensing). But the first point emphasizes that "It's more than just code," and Hall ends his article by attributing FreeDOS's three-decade run to "the great developers and users in our community." In celebrating FreeDOS, we are celebrating everyone who has created programs, fixed bugs, added features, translated messages, written documentation, shared articles, or contributed in some other way to the FreeDOS Project... Here's looking forward to more years to come!
Jim Hall is also Slashdot reader #2,985, and back in 2000 he answered questions from Slashdot's readers — just six years after starting the project. "Jim isn't rich or famous," wrote RobLimo, "just an old-fashioned open source contributor who helped start a humble but useful project back in 1994 and still works on it as much as he can."

As the years piled up, Slashdot ran posts celebrating FreeDOS's 10th, 15th, and 20th anniversary.

And then for FreeDOS's 25th, Hall returned to Slashdot to answer more questions from Slashdot readers...

America's Justice Department "is pushing for Boeing to plead guilty to a criminal charge," reports Reuters, "after finding the planemaker violated a settlement over fatal 737 MAX crashes in 2018 and 2019 that killed 346 people, two people familiar with the matter said on Sunday." Boeing previously paid $2.5 billion as part of the deal with prosecutors that granted the company immunity from criminal prosecution over a fraud conspiracy charge related to the 737 MAX's flawed design. Boeing had to abide by the terms of the deferred prosecution agreement for a three-year period that ended on Jan. 7. Prosecutors would then have been poised to ask a judge to dismiss the fraud conspiracy charge. But in May, the Justice Department found Boeing breached the agreement, exposing the company to prosecution.
A guilty plea could "carry implications for Boeing's ability to enter into government contracts," the article points out, "such as those with the U.S. military that make up a significant portion of its revenue..." The proposal would require Boeing to plead guilty to conspiring to defraud the U.S. Federal Aviation Administration in connection with the fatal crashes, the sources said. The proposed agreement also includes a $487.2 million financial penalty, only half of which Boeing would be required to pay, they added. That is because prosecutors are giving the company credit for a payment it made as part of the previous settlement related to the fatal crashes of the Lion Air and Ethiopian Airlines flights. Boeing could also likely be forced to pay restitution under the proposal's terms, the amount of which will be at a judge's discretion, the sources said.

The offer also contemplates subjecting Boeing to three years of probation, the people said. The plea deal would also require Boeing's board to meet with victims' relatives and impose an independent monitor to audit the company's safety and compliance practices for three years, they said.
"Should Boeing refuse to plead guilty, prosecutors plan to take the company to trial, they said..." the article points out.

"Justice Department officials revealed their decision to victims' family members during a call earlier on Sunday."

An anonymous Slashdot reader shared this report from the Verge: Threads will now let people like and see replies to their Threads posts that appear on other federated social media platforms, the company announced on Tuesday.

Previously, if you made a post on Threads that was syndicated to another platform like Mastodon, you wouldn't be able to see responses to that post while still inside Threads. That meant you'd have to bounce back and forth between the platforms to stay up-to-date on replies... [I]n a screenshot, Meta notes that you can't reply to replies "yet," so it sounds like that feature will arrive in the future.
"Threads is Meta's first app built to be compatible with the fediverse..." according to a Meta blog post. "Our vision is that people using other fediverse-compatible servers will be able to follow and interact with people on Threads without having a Threads profile, and vice versa, connecting communities..." [If you turn on "sharing"...] "Developers can build new types of features and user experiences that can easily plug into other open social networks, accelerating the pace of innovation and experimentation."

And this week Instagram/Threads top executive Adam Mosseri posted that Threads is "also expanding the availability of the fediverse beta experience to more than 100 countries, and hope to roll it out everywhere soon."

Tom's Hardware reports that Japan's National Institute of Information and Communications Technology (working with the Aston Institute of Photonic Technologies and Nokia Bell) set a 402 terabits per second data transfer record — over commercially available optical fiber cables. The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. One of the amplifiers this was demonstrated with is a thulium-based doped fiber amplifier, which uses C-band or C+L band systems. Additionally, semiconductor optical amplifiers and Raman amplifiers were used, which achieved 256 Tb/s data rate through almost 20 THz. Other amplifiers were also used for this exercise which provided a cumulative bandwidth of 25 THz for up to 119 Tb/s data rate.

As a result, its maximum achievable result surpassed the previous data rate capacity by over 25 percent and increased transmission bandwidth by 35 percent.
"This is achievable with currently available technology used by internet service providers..." the article points out.

"With 'beyond 5G' potential speeds achievable through commercially available cables, it will likely further a new generation of internet services."
