The results of the data transmission experiment were presented at the International Conference on Laser and Electro-Optics (CLEO) 2022 on May 19th, 2022.

Researchers from the National Institute of Information and Communications Technology (NICT) managed to transmit 1.02 petabits of data per second using multi-core fiber (MCF) with a standard cladding diameter of 0.125 millimeters. The NICT broke the one petabit per second data transmission rate first in December 2020 but did so with a 15-mode optical fiber.

Such a transmission system requires complex MIMO (multiple-input and multiple-output) digital signal processing to make sense of the signals and limits its practical applications. The latest transmission system uses 4-core MCF and can transmit 1.02 petabit per second over 51.7 kilometers (32.1 miles), compared to the 610 terabits per second previously achieved in a similar fiber.

"4-core MCFs are thought to be the most likely of the new advanced optical fibers for early commercial adoption. This demonstration shows their information carrying potential and is a significant step toward the realization of backbone communication systems that supports the evolution of Beyond 5G information services," the NICT wrote in a press release.

Adam grew up watching his dad play Turok 2 and Age of Empires on a PC in his computer room, and learned a love for video games through him. Adam was always working with computers, which helped build his natural affinity for working with them, leading to him building his own at 14, after taking apart and tinkering with other old computers and tech lying around. Adam has always been very interested in STEM subjects, and is always trying to learn more about the world and the way it works.
