The evolution of communication networks is clearly visible. If a few years ago we had a slow Internet, in the order of Kbps or Mbps, today everything is different. However, digital platforms and services are also increasingly demanding and work/research is underway to make the Internet even faster.
According to recent information, there is a new chip capable of transmitting 1.84 petabits of data per second.
1.84 petabits of data were transmitted over a fiber optic cable
We all want to have an even faster Internet and the truth is that the technology already exists for it. A new chip guaranteed the transmission of 1.84 petabits of data per second over a fiber optic cable, according to a News Scientist article last Thursday.
With this capacity and for comparison purposes, it is possible to download 230 million photographs in a single second. The project was led by Asbjørn Arvad Jørgensen from the Technical University of Denmark in Copenhagen.
To achieve such a feat, it was revealed that...
First, the team split the data stream into 37 parts, each sent to a separate core in the fiber optic cable. Then each of these channels was divided into 223 blocks of data that existed in individual slices of the electromagnetic spectrum. This "frequency comb" of equidistant light peaks across the spectrum allowed data to be transmitted in different colors at the same time without interference, greatly increasing the capacity of each core.
The 1.84 petabits per second were transmitted over 7.9 km of fiber optic cable. This means that if it is used, it will not only be a technology for local networks.
This new survey sets a transmission record using a single computer chip as the light source. The technology can help reduce energy costs while dramatically increasing bandwidth.
