Entire Netflix Downloaded In Seconds: Japan Breaks Internet Speed Record
It's a headline that could make any tech lover do a double-take. Researchers at Japan's National Institute of Information and Communications Technology (NICT) have achieved the fastest internet speed ever recorded, a mind-blowing 1.02 petabits per second. To put that into perspective, this is one million gigabytes per second, fast enough to download the entire Netflix library in a blink.
What's more astonishing is how they did it. Japanese engineers didn't use futuristic, oversized technology. Instead, they used fiber optic cables that are exactly the same size as those already in global use, meaning this isn't science fiction; it's a real breakthrough with very real-world potential.
'This speed is so fast that you can download 1,27,000 years of music or stream 10 million 8K videos at the same time," researchers said.
Although this lightning-fast internet isn't available for household use yet, the implications are enormous. The breakthrough lays the groundwork for the next generation of internet infrastructure, including 6G mobile networks and high-capacity undersea data cables – both critical to supporting the world's ever-growing appetite for data.
How They Did It
The record-breaking speed was achieved using an advanced 19-core coupled optical fiber system. Unlike conventional cables that have a single data path, these specially engineered fibers allow for multiple parallel data streams. The researchers successfully transmitted data at 1.02 petabits per second over a distance of 1,808 kilometres (1,118 miles) using standard-sized fiber.
This development is being hailed as a significant milestone in the ongoing evolution of digital connectivity. While consumer rollout is still years away, such research signals a major shift toward more powerful, scalable networks.
So, while you may not be able to download your favourite show at petabit speeds just yet, this breakthrough brings us one step closer to an era where buffering and lag become relics of the past.

India's Astronaut Shubhanshu Shukla Prepares To Return Home, ISS Undocking Today
Last Updated: The crew will return aboard SpaceX's Dragon spacecraft, with splashdown expected off the California coast on July 15 at around 3:00 pm IST Group Captain Shubhanshu Shukla, India's first astronaut to visit the International Space Station (ISS), is set to undock from the orbiting lab today at 4:30 pm IST. Shubhanshu Shukla participated in the Axiom-4 (Ax-4) mission along with three international crew members: Commander Peggy Whitson, and Mission Specialists Sławosz Uznański-Wiśniewski and Tibor Kapu. The crew will return aboard SpaceX's Dragon spacecraft, with splashdown expected off the California coast on July 15 at around 3:00 pm IST. Shukla's return marks the end of a landmark mission that highlighted India's growing role in international space collaboration and scientific research. During their 18-day stay on the ISS, the Ax-4 crew conducted over 60 scientific experiments across biology, AI, materials science, and human health. Among Shukla's key contributions was the Sprouts Project, which examined how microgravity influences seed germination and early plant growth — research aimed at supporting future space agriculture. He also led experiments on microalgae, assessing their ability to generate food, oxygen, and biofuels in space. Additionally, the crew tested glucose monitoring devices in microgravity to support future astronauts with diverse health needs. Other experiments included studies on mental health and evaluating next-generation spacesuit materials. Shukla had a video interaction with Prime Minister Narendra Modi and a phone call with ISRO Chairman V Narayanan during the mission, discussing scientific progress and the upcoming Gaganyaan human spaceflight project. At a farewell ceremony aboard the ISS on July 13, Shukla thanked ISRO, his crewmates, and the people of India. 'This mission is not just a personal milestone, but a proof to what humanity can achieve together. I hope our work inspires young minds in India and across the world to dream beyond boundaries," he said. Reflecting on India's space journey, Shukla added, 'Today, India looks ambitious from space, fearless, confident, and proud. India is still saare jahan se accha." Following undocking, the crew will spend approximately 21 hours travelling back to Earth. After splashdown, Shukla will undergo a week-long rehabilitation program to help his body adjust to gravity. His family is preparing a warm welcome as he returns home after making history. The Ax-4 mission is seen as a key step in India's preparations for the Gaganyaan mission and the country's broader ambitions in human spaceflight. view comments First Published: July 14, 2025, 08:41 IST Disclaimer: Comments reflect users' views, not News18's.

Our homegrown talent to power electronics leap
Recent reports of foreign engineers being withdrawn from India's electronics supply chain have triggered concern. But let's not confuse the symptom with the real issue. The question isn't who's entering or exiting — it's whether India's domestic talent pool is strong enough to power the country's electronics manufacturing ambitions. I've had the privilege of building India's electronics story from the ground up with some like-minded people — starting with Nokia, where we brought in over 33 global suppliers, and now at Zetwerk. But my roots go deeper — I'm a fifth-generation Chennaiite, with my family in Madras since the 1880s. I've seen the evolution of Indian industry firsthand, and one thing is clear: we have the people. But we must skill and scale them differently. The electronics industry needs more than engineers. It needs system thinkers who understand both individual processes and how they fit together. Let me illustrate this. At our factory launch in Tamil Nadu, IT Minister Ashwini Vaishnaw visited and struck up a conversation with a young associate on the line — they were soon chatting fluently in Odia. This wasn't a photo-op. It was a reflection of our mobile, multilingual, and motivated workforce. India is a full-spectrum employee base. From Bihar to Odisha to Rajasthan, young workers are showing up across factories — ready to learn.

We need: SMT (Surface Mount Technology) line operators Cleanroom and ESD-safe assembly technicians Test engineers trained for 5G systems Automation specialists and robotic cell programmers Equipment and tooling maintenance experts Program managers and supply chain professionals who can manage material dynamics and just-in-time inventory For instance, while India has strong support for standard machines, special purpose machines (SPMs) — often used for advanced testing or calibration — require targeted training and vendor support. In 2005, while at Nokia, I called a meeting with electrical equipment vendors and asked a simple question: "Where is your support team going to be based?" If the answer was "outside India," they were out. Then I asked, "Where will your L2 spare parts — the more expensive, non-consumable ones — be supplied from?" With help from companies like NMTronics, we built that local capability. That's the model we need to replicate today. At Nokia, we sent our test engineers to Korea for three weeks, where they were trained — and even hosted by a friend who cooked them vegetarian meals. The point is: if the machine is Japanese, we send engineers to Japan. If it's Chinese, we arrange short-term stints with a clear process. But building strong local bench strength is essential. We saw this in action during the transition from 4G to 5G phones amid the Covid-19 pandemic. Test systems were made by the team in India and validated remotely — and our Indian team managed it successfully. We don't need long-term dependency on training from abroad. If temporary support is needed, fine. But let's ensure knowledge transfer is built in. We already have successful precedents. Nokia localized 35% of phone components in India — long before PLI. Today, with better policy support, we can go further. Here's how: Electronics-specific skilling academies with curricula co-created by industry Certification programs benchmarked to global standards, much like how India's software boom standardized Java and Python Twinning programs with Taiwan, Japan, Korea — sending engineers for hands-on training National registry of certified electronics technicians and process engineers Incentives for in-house training academies run by OEMs and ODMs We now need scale. We must build not just shop-floor readiness, but capability to design the next generation of factories and machines. India's past success in software was built on a foundation of policy, people, and purpose. We now need a similar Y2K moment — for electronics hardware. Supply chains are going "blended" — with components made in one country, modules in another, and assembly elsewhere. India can play across all three — but only if we equip our workforce.
