Fiber optic transmission reaches new heights

Add as a preferred source on Google

Bandwidth junkies rejoice! A group of engineers at the University of California, San Diego, reported in Science earlier this week that they have successfully surpassed the fiber optic transmission capacity limit.

“This advance,” writes the UC San Diego News Center, “has the potential to increase data transmission rates for the fiber optic cables that serve as the backbone of the Internet, cable, wireless and landline networks.”

To be clear, this now means optic signals can be transmitted over longer distances without obstruction, according to BGR. The breakthrough is the result of an optical engineering experiment in which university researchers were able to boost the intensity of the fiber optic signal by 2,000 per cent. Consequently, the optic signals were transmitted over 7,456 miles without any hindrance in quality, a record-breaking achievement.

While high power in optic signals typically provoke interruption, referred to by scientists as “crosstalk”, such conflicts are easily predicted among highly-regarded engineers. Ergo, researchers knew just when to reverse the signal as it approached its target.

Nikola Alic, one of the researchers who partook in the study, described its significance in a published report:

Today’s fiber optic systems are a little like quicksand. With quicksand, the more you struggle, the faster you sink. With fiber optics, after a certain point, the more power you add to the signal, the more distortion you get, in effect preventing a longer reach. Our approach removes this power limit, which in turn extends how far signals can travel in optical fiber without needing a repeater.

Still, while this is a crucial accomplishment to ensure the eternality of the World Wide Web, there’s a lot more room for improvement that will need to be addressed before introducing this advancement to the everyday Internet user. On the bright side, this could mean a great deal for the future of data transmission speeds in relation to service pricing over the next several years.

South Korea wants to give every citizen free, unlimited access to its own AI chatbot
The government-backed service could turn generative AI into public infrastructure instead of another monthly subscription

South Korea wants to give every citizen free access to an AI chatbot with no usage limits. That puts the technology closer to a public utility than another premium service demanding a monthly subscription.

The Ministry of Science and ICT announced the AI for Everyone project on July 13. Private companies will build the platform around locally developed models, while a separate AI agent will help people navigate government services. It’s a more practical job than generating emails or settling arguments nobody wanted to research themselves.

Ever since AI chatbots arrived on the scene, there has been one aspect that has worried lawmakers and experts a lot: humans forming emotional connections with chatbots. There have been plenty of cases where over-reliance on these AI companions or partners has resulted in medical emergencies, lost lives, and triggered multiple lawsuits against the likes of OpenAI and Meta.

Russian hackers keep finding their way into critical networks through neglected routers
A multinational warning says outdated firmware, weak passwords, and insecure settings are giving state-backed attackers an easy opening

Russian state-backed hackers have spent more than a decade exploiting a stubborn weakness in critical infrastructure networks. Organizations are still leaving poorly configured and outdated routers exposed to the internet.

In a joint cybersecurity advisory, the NSA, CISA, FBI, and international partners warn that hackers linked to Center 16 of Russia’s Federal Security Service are continuing to target vulnerable networking equipment. Energy, healthcare, and government networks are among the sectors facing the highest risk.
