44.2 terabits per second: the new speed record for Internet speed

A team of Australian researchers set a new record by reaching 44.2 Tbps on a single optical fiber. Thanks to a tiny chip, they managed to transmit the equivalent of 1,000 HD movies in one second over standard optical fiber.

While the fastest fiber optic offers from French access providers are around one gigabit per second, Australian researchers have managed to establish a connection 44,000 times faster. In an article published in Nature Communications, a team from Monash, Swinburne, and RMIT universities created a new tiny optical chip that allowed them to reach a transfer speed of 44.2 terabits per second.

Unlike previous records, this rate has not been reached in a laboratory. The researchers used a single standard optical fiber 75 km long, which links the campuses of Monash and RMIT universities. The chip incorporates a technology called optical micro-comb, which makes it possible to transmit data more efficiently. The researchers opted for a specific class, called crystal of solitons .

An integrated chip to increase the capacity of existing networks

This discovery represents an inexpensive way to improve the networks already in place. “In the long term, we hope to create integrated photonic chips that would achieve this kind of data throughput on existing fiber optic links with minimal cost,” said Professor Arnan Mitchell of RMIT University .

The whole point of this research lies in the fact that operators could equip their current networks to increase their capacity without having to install new optical cables . The first interested in this technology will undoubtedly be the data centers . Produced on a large scale, this optical chip could one day be used to boost residential fiber connections.
