The innovation of the Internet that can transfer 178 terabytes per second
A team at University College London has succeeded in building an Internet capable of transmitting data at a rate of 178 terabytes per second, which is similar to downloading every library of the famous “Netflix” series in less than a second, breaking the record for the fastest data transfer rate in the world.
The researchers in London achieved the new record by sending data over a network of much wider wavelengths than optical fibers, where conventional infrastructure uses up to 9 terhz (THz), while the team used 16.8THz.
The team started their way to fame by combining different communication enhancement techniques, which can enhance signal strength on a larger scale, and then increased the speed by developing a new engineering modulation to manipulate the characteristics of each individual wavelength.
The researchers chose this technology, because it can be added to the current infrastructure at a reasonable cost, as it will only require updating the optical fiber cables, as the cost of the new method is about $ 20,000, while the cost of installing new optical cables is about $ 600,000.
Team Leader Dr Galdino said: “While the current state of the art cloud data center connections are capable of transmitting up to 35 terabytes per second, we are working with new technologies that use the existing infrastructure more efficiently, making better use of the optical fiber bandwidth. “.
