Japan still holds the fastest internet speed recorded in history at 319 terabits per second

-

  • Researchers at Japan’s National Institute of Information and Communications Technology, who have been attempting to push the limits of online information transfer, achieved a new world record with an internet speed of 319 Terabits (TBs) per second.
  • The researchers attained previously unseen speeds by employing modern fiber-optic technology and a 4-core optical fiber with a standard outer diameter of 0.123 mm for the test.
  • According to reports, the test exceeded the previous record of 178 Tb/s set by Japan and the United Kingdom in 2020.

A study given at the International Conference on Optical Fiber Communications in June 2021, engineers in Japan broke the global record for the fastest internet speed.

Researchers at Japan’s National Institute of Information and Communications Technology, who have been attempting to push the limits of online data transfer with an internet speed of 319 Terabits (TBs) per second.

The new record was set on a 1,864-mile-long (3,000-kilometer-long) network of fibers. And, most importantly, it is compatible with modern cable infrastructure.

The researchers attained previously unseen speeds by employing modern fiber-optic technology and a 4-core optical fiber with a standard outer diameter of 0.123 mm for the test.

According to reports, the test exceeded the previous record of 178 Tb/s set by Japan and the United Kingdom in 2020.

To put things in context, the new speed is about 7 million times quicker than the average internet connection in the United States. And a staggering 24 million times faster than India’s average speed.

The experiment in Japan was accomplished in a lab, where the researchers built a recirculating transmission loop by joining two earth-doped fiber amplifiers.

With the help of erbium and thulium doped fiber amplifiers and distributed Raman amplification, the scientists were able to extend the signal for almost 3,000 kilometers.

“The 4-core MCF with standard cladding diameter is attractive for early adoption of SDM fibers in high-throughput, long-distance links, since it is compatible with conventional cable infrastructure and expected to have mechanical reliability comparable to single-mode fibers,” the Japanese research institute said the paper published earlier this month.

The most significant positive conclusion of the study was that the testing was mostly conducted on fiber optic infrastructure, which is already the primary cable for internet connection in the majority of countries.

Optical fibers are substantially faster than traditional copper wires as it’s commonly used by ISPs like Philippine’s PLDT, Converge ICT, and more.

Meanwhile, PLDT Home remains undisputed as the fastest broadband network in the Philippines, dominating telco rivals with a Speed Score™ of 77.24 at the Ookla® Speedtest Awards™ for Q3-Q4 2021.

Latest data from the global benchmarking company also showed PLDT besting all other internet service providers (ISPs) in the country with top upload and download speeds of 217.07 Mbps and 203.97 Mbps, respectively.

In November 2021, PLDT Home launched the country’s first-ever 10,000 Mbps fiber-optic service in the Philippines, putting the country alongside first-world nations that have access to such ultra-fast home internet speeds such as South Korea, Japan, Sweden, Norway, Italy, New Zealand and USA.

In Manila, PLDT bested major ISPs – including Converge, Globe and Sky – with upload and download speeds of 54.52 Mbps and 58.57 Mbps, respectively. In Cebu, PLDT recorded 76.14 Mbps and 74.22 Mbps upload and download speeds, respectively. In Davao, PLDT is the fastest fixed network over ISPs Globe and Sky, with upload and download speeds of 70.06 Mbps and 71.50 Mbps, respectively.
