Fiber optic cable transmits 255 terabits per second

New record

Dutch and American researchers have now succeeded for the first time in increasing data transmission in fiber optic cables by a factor of 21. It is now possible to send data at 255 terabits per second through the new fiber optic cable – a new record!

Florida (United States). Increasing bandwidth problems, especially for large data centers, are presenting more and more companies with large and expensive challenges. If the higher bandwidth was urgently required, a new cable had to be laid – and that at the expense of the company. However, since the financial outlay for this is enormous, only extremely large companies can afford this luxury. A new type of fiber optic cable developed by researchers at Eindhoven University of Technology and the University of Central Florida could solve these problems in the future. It enables the transmission of enormous amounts of data and brings data transmission in the petabit range within reach. A dream for every IT company.
Barely thicker but 21 times more efficient

The new fiber optic cable is barely thicker than the traditional fiber optic cable, although two additional orthogonal dimensions have been added. As a result, additional light signals are sent through the fiber optic cable at even closer intervals. In addition, the researchers were able to increase the number of light cores from two to seven, which is also a significant increase.

For comparison: With this new fiber optic cable, it is possible to transfer one gigabyte of data in just 31.24 microseconds.

However, it is questionable whether this new fiber optic cable will actually be used in the next few years. In Germany, for example, new fiber optic lines are currently being laid across the board. However, the old cables are still used here.
