japoneses multiplican el tráfico de Internet

Inspenet, December 10, 2023.

Japanese engineers have achieved a milestone by multiplying Internet traffic, reaching an impressive speed of 22.9 petabits per second over a single optical fiber, more than doubling their previous record of 10.66 petabits per second, according to a Press release.

This extraordinary speed is more than 20 times the total global Internet traffic in a single second. The term ‘global Internet traffic per second’ refers to the entire volume of data transmitted around the world over the global Internet network in a single second, covering diverse activities such as web browsing, video streaming, file downloads, online games and any other data exchange between devices connected to the Internet.

Although most of the world experiences Internet browsing speeds of a few hundred megabits per second, the remarkable speed achieved by Japan’s National Institute of Information and Communications Technology (NICT) significantly exceeds even consumer connections. faster.

In their effort to handle a greater volume of Internet traffic, NICT researchers explored multiplexing technologies that take advantage of space and wavelength in fiber optic communications. This is similar to the expansion of highways, using multiple lanes and traffic signals to make the Internet faster and capable of handling greater data flow.

Advancement in Internet traffic

The researchers found that each core of the fiber cable had the capacity to transmit data at speeds between 0.3 and 0.7 petabits per second. Combining all cores, the total speed reached a staggering 22.9 petabits per second.

The NICT team achieved this milestone by implementing cutting-edge technologies. Instead of relying on a single core for data transmission, its cable features 38 cores, each capable of transmitting data in three modes, generating an impressive total of 114 spatial channels. This expands the total transmission capacity by employing several independent data channels in different wavelength bands.

Each mode is located in its own spatial channel, with 750 wavelength channels in the S, C and L bands, resulting in a bandwidth of 18.8 terahertz.

The combination of these technologies results in a data transmission speed of 22.9 petabits per second. NICT specialists suggest that with further optimization in error correction, the system could potentially increase up to 24.7 petabits per second, exceeding the speed of current fiber optic communication systems by more than 1,000 times.

The demonstration is an important step toward realizing future high-capacity optical communication networks ,” the researchers said in the press release.

In contrast, NASA’s Internet speed appears to be as slow as a dial-up connection. The presentation of this document took place during the 49th European Conference on Optical Communications (ECOC 2023), which was held in October.
