A remarkable new optical fiber technology has set a record-breaking data transfer speed, allowing users to download the entire Netflix library in less than a second. This achievement is made possible by a revolutionary fiber optic cable that features 19 cores within a compact diameter of just 0.125 millimeters, which is the same size as conventional single-core cables. This innovative design enables the transmission of 19 times more data while minimizing data loss by ensuring uniform light conduction. To achieve transmission over a distance of 1,120 miles—similar to the distance between New York and Chicago—the signal was amplified an impressive 21 times.
This new record marks a significant increase from last year’s figure of 50,250 gigabits per second (GB/s), more than doubling previous speeds. Although the NICT team accomplished comparable speeds in 2023, they did so over only a third of the distance. The advancements in signal amplification and the reduction of data loss have paved the way for this remarkable achievement. Moreover, the new technology is designed to seamlessly integrate with existing fiber optic infrastructures.
As the demand for data continues to surge globally, with volumes increasing by approximately 50 percent annually according to Nielsen’s Law, this innovation could address pressing data needs. The capability to retrofit these new cables into current networks is particularly promising for countries where fiber optic growth has stalled. While the record has yet to be independently verified, it demonstrates the potential of fiber optics to influence the future of internet connectivity in transformative ways.
