New fiber optic core increases an Internet speed by 100 times

A scientists group from the RMIT has improved the fiber-optic data transmittance technology using “swirling light”, reports one of the most read daily Newspapers in the UK The Guardian.
Fiber optic cables transmit information in light pulses form. “Swirling light” is a light beam that does not just fly forward, but also revolves around its movement direction. This method allows more rays to be transmitted over a single cable, increasing the Internet bandwidth. If you depict this “spun light” schematically, it will look like a DNA spiral.
Earlier, American researchers have already developed optical fiber to transmit “swirling light”, but scientists from RMIT optimized this technology for use in a mobile application. Previously, reading “twisting” information required bulky large equipment, and the new chip – less than 80 micrometers.
According to the developers, when this method is commercialized, it will increase the Internet speed at least 100 times.
Data transfer based on this technique has already been carried out previously:
1. Summer 2012 – some group of researchers from Boston University and the southern California University using the “twisting” light method, received a transfer rate of 2.56 tbit/sec in the open air
2. Summer 2013 – the same scholar group implemented data transmission at a rate of 1.6 terabits per second through a fiber optic cable one kilometer long.
3. In 2017 a researchers team from different countries built a network of the last mile with a 1.6 km total length, in which data is transmitted using a “spun ” light.
4. November 2016 – another important step was taken in the study of the “spun” light potential as a means of data transmission. Austrian and Canadian physicists were able to forward it at 143 km — the longest channel of this type in the history of research.
