Under very limited and controlled laboratory conditions, it has been possible to reach a dizzying figure of 178 Terabits per second in data transmission from the internet.
Researchers from the UCL (University College London) have managed to set a new world record in terms of data transmission speeds from the internet. Making use of a single fiber optic cable with an extended spectral range, they have been able to transfer data at a speed of 178 Tbps, or what is the same, 22.25 TBps. At this speed, the entire Netflix library can be downloaded in its entirety in less than a second, we would only have to have enough space, the adequate network infrastructure, and storage units that support that download.
Normally, when operating with fiber optics, frequencies with a bandwidth of 4.5 to 9 THz are used, but the UCL researchers have increased this bandwidth to 16.8 THz by using modified amplifiers and developing new algorithms for the reading data from extended frequency waves. In this way, the previous record in this area has been left behind and its figure increased by 18% (the previous one stood at 150 Tbps). Although the information has only traveled 40 km from its departure to its arrival, these speeds are still inconceivable for the user on foot.
