Fiber-optic Data Transfer Hits Blistering 301 Tbps — A Mind-Boggling 1.2 Million Times Faster Than Average Broadband
In a groundbreaking achievement, researchers have shattered records by achieving data transfer speeds of 301 terabits per second (Tbps) through existing fiber-optic cables. This rate, equivalent to streaming 1,800 4K movies in a single second, dwarfs the typical home broadband connection by a staggering 1.2 million times.
The breakthrough, detailed in a recent publication by the Institute of Engineering and Technology (IET), marks a significant leap forward in fiber-optic technology. By harnessing an untapped transmission band known as “E-band,” scientists were able to push the limits of data transfer speeds beyond anything previously imagined.
Traditionally, commercial fiber-optic connections operate within the C-band and L-band portions of the infrared spectrum. However, with the exponential growth of internet traffic, these bands are projected to become congested, necessitating the exploration of additional transmission bands like the E-band.
The E-band, while promising for its expanded bandwidth, presented significant challenges due to high levels of data loss caused by the absorption of hydroxyl (OH) molecules. To overcome this hurdle, researchers developed innovative optical amplifiers and gain equalizers, ensuring stable data transfer at unprecedented speeds.
Professor Ian Phillips, from Aston University in the U.K., highlighted the significance of their achievement, noting that their system successfully emulated E-band channels in a controlled manner, a feat previously thought impossible.
While the achieved speed of 301 Tbps is remarkable, it’s worth noting that other research teams have pushed the boundaries even further. For instance, a team at NICT achieved a world record speed of 22.9 petabits per second in November 2023, utilizing wavelength division multiplexing (WDM) technology over a distance of 8 miles.
In summary, this breakthrough not only showcases the incredible potential of fiber-optic technology but also underscores the relentless pursuit of faster and more efficient data transmission methods in the digital age.
