We note that this new 3.2 Pb/s real-time optical transfer speed world record comfortably eclipses the 2.5 Pb/s record set by the same teams earlier this year. The improvement represents an almost 30% performance uplift within a year.
According to the source, these speeds could mean, if and when they are successfully rolled out, “3.2 million households simultaneously enjoying gigabit broadband.” Or you could say this speed is roughly 3.2 million times faster than a typical one-gigabit internet connection . Both are probably more useful and practical comparisons than knowing that one person would be able to download 20,000 4K movies in a single second.
In technical terms the 3.2 Pb/s test proved the success of the spatial division multiplexing and S+C+L multi-band transmission technology used by the team. Major hurdles faced by the researchers included crosstalk interference, and handling the varying spec requirements of the S+C+L transmission bands.
The new 3.2 Pb/s transmission record was achieved using commercially compliant hardware architectures in real-time. Thus, the headlining result could be practical and deployable in the real world in the not-too-distant future, with enough will and effort.
