An optical microcircuit invented that increases Internet speed to 44.2 Tbps

A team of Australian researchers has developed a chip with multiple infrared lasers that allows huge amounts of data to be transmitted over existing infrastructure.

The fastest commercial Internet available in Singapore today, with an average download speed of 197.3 Mbps. In most other countries, this figure is in the region of 40-50 Mbps. As the complexity of the content increases, increases and the need to increase the data transfer rate. For example, during the period of increased quarantine, some providers deliberately degraded the quality of traffic in order to avoid congestion..

However, scientists from the Universities of Monash, Swinburne and Royal Melbourne University of Technology announced the development of technology that allows data to be transmitted over fiber optic cables at speeds of up to 44.2 Tbit / s. According to them, a record figure was achieved thanks to a new optical microcircuit of the type «micro-crests».

The presented chip is smaller and lighter than existing telecommunications devices, but replaces 80 lasers, generating many tiny equidistant signals of different frequencies in the infrared spectrum, each of which serves as a separate communication channel..

This system is fully compatible with existing fiber-optic Internet infrastructure, so it was tested on an active 76-km network between the campuses of Royal University of Technology, Melbourne and Monash Clayton University. To simulate the peak internet usage during testing, the researchers sent the maximum amount of data through each channel at 4 THz.

The development team expects that in the next 2-3 years, researchers from all over the world will significantly improve the technology and in 5 years its commercial application will begin..

Although today users do not need an Internet speed of 44.2 Tbps, since it is a million times faster than the current average and allows you to download 1000 HD movies per second. However, as the Internet of Things, cloud computing, virtual and augmented reality, and unmanned vehicles evolve, network bandwidth will need to expand, especially for companies..

We also previously reported that scientists were able to transfer data at a speed of 1 Tbps through a pair of copper wires.
