What’s going on in Japan?

The new date of a few weeks, but had rather passed under radars. Moreover. Therefore, It was around a tweet again on July 10, 2025 that the subject rebounded: ” Japan breaks the world’s internet speed record with 1.02 petabit per second, is enough to download the full Netflix in a second », Is it written.

This message, relayed more than 14,000 times on X (ex-Twitter) and given more than 3.2 million times, is spectacular, although Anexact. Similarly, It actually refers to an announcement spent at the end of May by the National Institute what’s going japan? new of Information. Furthermore, Telecommunications Technologies (NICT), the main research center of Japan in the fields of IT what’s going japan? Nevertheless, and digital.

The NICT teams welcomed themselves to have been able to reach a ” global record for capacity. In addition, transmission distance With an optical fiber. Furthermore, Indeed, there was talk of a flow that reached the rate of 1.02 petabit per second. Similarly, This, over a distance of 1,808 kilometers, with a fiber with 19 optical cores (in a standard sheath diameter).

Many figures, which require comparison points to grasp what we are talking about. Furthermore, This is roughly the distance which separates Paris from Tallinn. However. Furthermore, in Estonia, or, as indicated in the press release, a Berlin-Naples, a sapporo-fukuoka (that is quite close to the length of the Japanese archipelago) or even a Missouri-Montana, across the Atlantic.

If one could easily represent the distance in what’s going japan? new play in this test. Meanwhile, including without needing these geographic references, the flow is less obvious to identify, without some technical knowledge. what’s going japan? However. We can however try a few perspective, to give some fork ideas of what it would be possible to do.

What represents 1.02 petabit/second? – What's going japan? – What's going japan? new

1.02 Petabit is 0.1275 Petaoctet (petabyte in English).

However, according to an article from what’s going japan? The Verge in 2013, the Netflix TV films and TV emissions occupied a space of 3.14 petacts. This means that with the optical fiber in question. we could transfer the entire catalog of the SVOD giant in the space of 25 seconds.

Indeed, 1 byte (Byte) is equivalent to 8 -bit. Consequently, 3.14 petacts are worth 25 petabits.

Obviously. nothing says that the Netflix catalog still occupies this same space in 2025. there is not the question – especially since, as the Verge notes, the value indicated more than 10 years ago was already reduced to 2.75 in (petacts) via compression and optimization of content for devices. It is the order of magnitude that matters and. in any case, the servers of Netflix would not support such an absorption flow.

Moreover. even if we doubled the weight of the Netflix catalog starting from the principle that it has increased sharply over the years. this would not quite change the world. We would go to a waiting period which would reach around 50 seconds. The prospect of recovering everything in less than a minute is enough to dream.

But what’s going japan? new we can what’s going japan? establish other rapprochements. The total size of the digital storage of the Congress Library, in the USA? 174 in estimated transfer time, with such a fiber? Around 23 min. The annual data (30 in) of the great collision of Hadrons (LHC)? It is completed in almost 4 min.

In his commentary, the NICT points out that the fiber optical records have been regularly broken. His table also combines data that seem messy. The Japanese Institute notes that it should not be looked at that the flow. but it is also what’s going what’s going japan? new japan? necessary to take into account the distance.

However, if larger speeds have been reached in the past (1.7 petabit in March 2023), it was over an almost anecdotal distance in comparison (63.5 km) in fact. the April 2025 record, made public in May, constitutes the best relationship capacity x distance with a threshold at 1.86 exabit/s · km (against 1.71 in October 2023).

The success of the NICT. remarkable, are obviously very far from what the all-new uses daily via the internet fiber optic plans. To have an idea, the average fiber flow in France is currently 456 Mbit/s for download – say 500 Mbit/s. Compared to the Japanese record, the ratio is… 2,040,000.

In other words, a flow rate of 1.02 petabit/s is therefore approximately 2.04 million times faster than a general public fiber of 500 Mbit/s. It’s just dizzying. But. it is also the blatant demonstration that what’s going japan? new fiber what’s going japan? optics still has resources and that its performance can largely be improved over time.

« This is an important step in carrying out future long -distance. large capacity optical communication systems “, Besides, commented the NICT. This success ” should contribute significantly to […] the long -term extension of the optical communication infrastructure in the future. when demand increase ». That’s good: this is the case.
