The cable demonstrated data transmission over a distance of 63.5 km.
A research team from the National Institute of Information and Communication Technologies (NICT) and other renowned European universities has developed an optical fiber with 19 cores and a standard sheath diameter (0.125 mm). diameter according to TechExplore.
This cable demonstrated data transmission at a rate of 1.7 Petabits per second (1 Petabit equals 131,072 Gigabytes – ed.) at a distance of 63.5 km. A random core-to-core optical fiber design was used along with multiple input-output (MIMO) digital signal processing to eliminate signal crosstalk between cores to achieve high core density. This experiment set a world record for the throughput of a standard coating diameter optical fiber, as well as a world record for the longest transmission distance between data transmission experiments with an efficiency of 1 Petabit per second or more.
This result shows the possibility of significantly reducing the power consumption of digital signal processing in offshore systems. The technology will facilitate the realization of future long-range and capacitive optical communication networks.
Research into the development of advanced optical fibers is of great interest due to the increasing demand for data transmission worldwide and artificial intelligence in the global Internet era.
