Chinese team claims astonishing new fiber transfer speed world record — incredible 3.2 Petabits per second transfer is the same as downloading over 20,000 4K movies in a second
Chinese researchers report 3.2 Pb/s real-time transmission across a 24-core fibre, surpassing their earlier record but remaining below higher laboratory benchmarks
Researchers in China have achieved a groundbreaking data transmission speed of 3.2 Petabits per second using a 24-core optical fiber. This remarkable feat, reported by Chinese researchers, is equivalent to downloading over 20,000 4K movies in a single second. The team, comprising specialists from various institutions, utilized spatial division multiplexing and S+C+L multi-band transmission to surpass their previous record of 2.5 Petabits per second.
The S, C, and L bands use different wavelength ranges, enabling simultaneous transmission across a wider section of the optical spectrum. While the Chinese group's claim is notable, it does not surpass laboratory research that has reached 5.29 Petabits per second using similar technology. However, the latter may rely on advanced processing methods and specialized equipment unsuitable for routine network deployment.
The Chinese team's use of commercially compliant hardware is significant, but the lack of official deployment schedule, pricing information, and independent assessments means that the technology's practical viability remains uncertain.
