Tremendous data transfer record clock of over 1 petabit per second

An anonymous reader cites a report from New Atlas. Japanese researchers Set new speed records for data transfer. — Incredibly fast 1.02 petabits per second (Pb/s). What’s more, innovation was achieved with fiber optic cables that had to be compatible with the existing infrastructure. For reference, 1 petabit is equivalent to 1 million gigabits. That means this new record is about 100,000 times faster than the fastest home internet speeds available to consumers. Even NASA could “only” get 400 Gb/s when ESnet6 launches in 2023. According to the team, at 1 Pb/s, it can theoretically broadcast 10 million channels of video per second in 8K resolution.

that much new record It was set up by researchers at the Japan Institute of Information and Communication Technology (NICT) using several new technologies. First, fiber optics contain four cores (glass tubes that transmit signals) instead of a regular core. Thanks to a technology called Wavelength Division Multiplexing (WDM), the transmission bandwidth has been extended to a record 20 THz. This bandwidth consists of a total of 801 wavelength channels spanning three bands: the commonly used C and L bands and the experimental S band. With the help of other new optical amplification and signal modulation technologies, the team achieved a record speed of 1.02 Pb/s transmitting data over 51.7 km (32.1 miles) of fiber optic cable.
