New Japanese Optical Fiber Reaches 1.02 Petabits Per Second and Could Revolutionize Data Transmission Worldwide

Japan has just set a new global milestone by developing an internet connection 4.25 million times faster than the Brazilian average. The achievement was announced by the National Institute of Information and Communications Technology (NICT), which reached the mark of 1.02 petabits per second, or about 127,500 gigabytes per second.

This advance comfortably surpasses previous records and promises to transform sectors such as artificial intelligence, cloud computing, and streaming. The achievement is even more impressive as it was accomplished with technology compatible with existing networks, which paves the way for practical large-scale application.

19-Core Fiber Ensures Historic Speed

To achieve this performance, NICT scientists developed a new optical fiber with 19 cores within a single cable that is only 0.125 millimeters in diameter — the same standard as the wires already used by providers. This compacting multiplies transmission capacity without requiring replacement of existing networks, representing a huge technical and economic advantage.

Speed Impresses Even in Practical Scenarios

The speed of 1.02 petabits per second represents an exponential leap compared to current available connections. For comparison, this transmission rate is 3.5 million times higher than the average internet speed in the U.S. and 4.25 million times above the Brazilian average, according to Speedtest Global Index data. In practice, it would be possible to download the entire Netflix catalog in less than one second.

This advancement is not just an academic feat. It has the potential to accelerate consumption of 4K and 8K content, cloud gaming, and artificial intelligence systems, in addition to allowing the safe and stable expansion of the so-called Internet of Things (IoT), where millions of devices exchange data in real time.

Technology Could Reach the Market Without Cable Replacement

According to NICT researchers, the new technology is compatible with existing infrastructures, which facilitates its progressive adoption by providers and data centers. This means that implementation in commercial and urban environments could occur without significant investments in network replacement — a common challenge in the telecommunications sector.

During the Optical Fiber Communication Conference (OFC 2025), held in Japan, the Photonic Networks Laboratory emphasized that the new fiber is also less vulnerable to light distortions, a common issue in long-distance transmissions. This extra stability is viewed as one of the greatest assets of the Japanese innovation.

Do you think Brazil should invest in technologies like this to overcome the lag in digital infrastructure?

Elon Musk’s internet comes to mobile: Starlink technology connects smartphones without an antenna via satellite, works even without carrier signal, already costs just US$10 extra in the US, and could arrive in Brazil as an included benefit.

Seven world powers including the US, China, and Russia are spending €22 billion on a reactor in the south of France that aims to confine plasma at 150 million degrees Celsius, ten times the temperature of the Sun’s core, using a magnetic field capable of lifting an entire aircraft carrier.

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

While Brazil has been discussing bullet trains for 16 years, China delivers 5 new high-speed lines in 2026, surpasses 50,000 km of HSR, and moves 1 billion passengers in a single year.

With a wingspan of 152 meters, 76 tires, and a capacity to carry 1,270 tons, the Boeing Pelican was the giant “flying ship” that promised to cross oceans close to the water on an invisible air cushion beneath its wings.

While countries spend billions to draw water from the sea, a Nobel-winning scientist creates a container-sized machine that extracts up to 1,000 liters per day from dry air and uses ultrasound to release water in minutes, even in the middle of the desert.

Belgium will sink 23 giant concrete caissons, each weighing 22,000 tons, in the North Sea to build the world’s first artificial energy island 45 km off the coast, forming offshore electrical walls.

Municipal buses in Rio will stop accepting cash starting May 30, and passengers will need to use a card or app to pass through the turnstile, in a change that promises to speed up boarding and reduce the handling of money by drivers.

São Paulo Metro takes a giant step: assembly of the cutting wheel of the “Hebe Camargo” Tunnel Boring Machine begins in Penha and promises to accelerate the expansion of Line 2-Green to Guarulhos.

Mars may rely on asteroids to come off the drawing board: scientists propose seeking metals in space, using other bodies as fuel stations, and facing journeys so slow that a Martian base would take generations to be built far from the current Earth.

Researchers in England have discovered an impressive mechanism in the brains of flies that could make robots and artificial intelligence systems much smarter, faster, and more accurate than the current technologies available on the market.

As Europe tries to reduce its dependence on fossil fuels, a plant in Spain begins producing renewable natural gas with green hydrogen and CO₂, injecting synthetic methane directly into the distribution network.
