Data travels up to 44.2 terabits per second. The results of the experiment, which took place in Melbourne, were published in the journal Nature Communication
Driven by the great global demand during the pandemic, scholars have developed a connection capable of making data travel a 44.2 terabits per second from a single light source, and to support high-speed connections for 1.8 million families in Melbourne and simultaneously billions of the world during peak periods.
Similar demonstrations so far had only been seen in the laboratory, but researchers have now reached this speed using existing infrastructure. They have changed how light frequencies are generated to carry bits along cables. The new method replaces 80 lasers with a single device – an optical chip known as a micro-comb – smaller and lighter than the hardware used for Internet communication.
“What our study shows is the ability of the fibers already in the field to be the backbone of communication networks now and in the future. We have developed something that is modular on future needs,” explained Corcoran. To prove the impact of these optical chips, the researchers installed 76.6 kilometers of optical fibers between the RMIT university and Monash campus, managing to send the maximum data from each channel and simulating peak use, with bandwidth of 4 terahertz. For the future they hope to create a network of integrated photonic chips by exploiting the connections of current optical fibers with minimal costs.
