A new world record in data transmission was achieved by Danish researchers at DTU (Technical University of Denmark), specifically the HSOC (High-Speed Optical Communications) group at DTU Fotonik.
The team surpassed a previous record set by researchers at the Karlsruhe Institut für Technologie, demonstrating that it is possible to transmit 43 terabits/second with a single laser in the transmitter. The previous record set by the German team was 32 terabits/second.
The international competition over data transmission speed aims to develop technology that can respond to the new data of the ever-increasing data traffic on the Internet, which is estimated to increase by 40-50% annually. In addition, there is an environmental interest in the whole matter, as the carbon dioxide emissions corresponding to the energy consumption of the Internet constitute more than 2% of emissions due to human activity worldwide, as noted in the relevant announcement of the university - which emphasizes that other industries do not increase by 40% annually. "Therefore, it is necessary to find solutions for the Internet that entail significant reductions in energy consumption while at the same time increasing bandwidth," it is stated in this regard. It is worth noting that in the past, DTU researchers achieved the highest combined data transmission speed, of the order of one petabit/per second - however, this involved the use of hundreds of lasers.
In this case, the researchers achieved the new record using a new type of optical fiber that they "borrowed" from Japanese telecommunications giant NNT. This type of fiber contains seven cores instead of the one used in conventional fibers, which makes it possible to transfer more data. Although it contains seven cores, the dimensions are the same as those of conventional versions.
The HSOC team at DTU Fotonik has held this record before. In 2009, they broke the “terabit barrier”, achieving transmission of over one terabit/second, again using a single laser.
