🚀 1 petabit per second: this new record allows downloading Netflix's entire catalog in 1 second

A team of Japanese researchers has achieved a record data transmission speed, opening up unprecedented possibilities for telecommunications. This technological leap could transform our digital usage.


This breakthrough, achieved by the National Institute of Information and Communications Technology (NICT), far surpasses current network performances. At 1.02 petabits per second, this feat relies on a major innovation in optical fiber technology. Such a data transfer speed would allow downloading Netflix's entire catalog in just one second.

A technological evolution in optical fiber

The scientists used a special fiber that multiplies transmission channels. This novel architecture improves capacity without increasing cable bulk.

The process is based on wavelength division multiplexing, a technique that uses different light colors to carry data. Over 800 channels were combined, optimizing throughput while reducing energy losses.

This performance was validated over a distance of 1,800 km (about 1,120 miles), proving its viability for long-distance applications. Unlike previous records, this technology uses infrastructure compatible with existing networks.

Potential applications across multiple sectors

Such bandwidth would enable transferring entire data libraries in seconds. Research centers and businesses could gain a decisive advantage in massive information processing.

Artificial intelligence and virtual reality fields would greatly benefit from this advancement. Data exchanges between remote servers would become nearly instantaneous, eliminating current latency constraints.

While currently reserved for professional infrastructure, this technology could eventually influence the evolution of consumer networks. Future 6G standards might draw inspiration from it to offer unmatched speeds.
