Fiber optic ‘twisted’ light could make the Internet 100 times faster


There is a new breakthrough in the world of the Internet, more precisely in fiber optics, which can achieve internet speeds up to 100 times higher than the current ones.

The research was announced in the Nature Communications journal, and according to scientists will allow to increase the speed of existing networks, increasing their efficiency in the process.

The fiber optic cable uses light to transmit information, but until now, it was only possible to send differentiated information by the color of the light beam and its orientation, but all this changes as we can bend the light and turn it into a spiral, thanks to a group of scientists from RMIT University in the United States, who was able to create a third dimension for the light to be able to carry information, known as the level of orbital angular momentum, rotation.

To better understand, in terms of appearance it is quite similar to the double helix representing the DNA, and the more this ‘twist’ is used, the more is the volume of information that can be stored and sent. Although curved fiber optic cables have already been created for some time, it was only now with this research that it was possible to create a detector of acceptable dimensions to read the information.

The previous detector technology, for comparison, was roughly the size of a dining table, while the new technology has roughly the width of a hair.

This can be a breakthrough for both business and residential connections, but it will only take effect in areas that have a complete fiber optic system, from the supplier to the end customer, since many of the fiber facilities only have fiber between the transformer and the customer, the connection of the station to the plant being made through the use of copper cable.

The only drawback is that although the new fiber system can work in a mixed mode, in order to enjoy its full efficiency, it would be necessary to replace the existing fiber networks, and possibly copper ones, in order to take advantage of all the speed that this new type of fiber can offer.
