Researchers at Japan’s National Institute of Information and Communications Technology have achieved a world record for the fastest Internet speed<\/strong><\/a>, demonstrating more than one petabit per second (Pbps) transmission capacity.<\/p>\n

The same institute previously achieved a 1 Pbps speed record in December 2020.<\/p>\n

While they had used a standard cladding diametre for the system to achieve that speed, it employed 15-mode optical fibre, which is not used in conventional fibre architecture.<\/p>\n

That required complex multiple-input-multiple-output (MIMO) digital signal processing to unscramble data signals multiplexed during transmission.<\/p>\n

To use such a system, MIMO needs dedicated integrated circuits, making it practically unfeasible for large-scale deployment.<\/p>\n

The researchers said they believed their new 1 Pbps system would be compatible with conventional cable infrastructure, helping to address the explosive increase in data traffic from information and communication services beyond 5G.<\/p>\n

How it worked<\/h3>\n

The latest system used fibre cables consisting of four cores with the standard 0.125mm cladding diameter.<\/p>\n

Through wide-band wavelength division multiplexing (WDM) technology, the researchers enabled 801 parallel wavelength channels, giving them access to a record 20THz optical bandwidth.<\/p>\n

That consisted of 335 wavelengths in the S-band, 200 in the C-band, and 266 in the L-band, each providing 25GHz.<\/p>\n

They also used mixed optical amplification systems to account for data loss over distance.<\/p>\n

With the combination of technologies, they could transmit at 1.02 petabytes per second over 51.7km.<\/p>\n

That figure is equivalent to 1.02 million Gbps per second \u2014 a million times faster than the fastest Internet speed available to South African home fibre users.<\/p>\n

The table below shows how the latest system compares to the previous noteworthy speeds the researchers hit with other demonstrations.<\/p>\n
