Aston University researchers are part of a team that has sent data at a record rate of 402 terabits per second using commercially available optical fibre.

This beats their previous record, announced in March 2024, of 301 terabits or 301,000,000 megabits per second, using a single, standard optical fibre.

“If compared to the internet connection speed recommendations of Netflix, of 3 Mbit/s or higher, for a watching a HD movie, this speed is over 100 million times faster.

The speed was achieved by using a wider spectrum, using six bands rather than the previous four, which increased capacity for data sharing. Normally just one or two bands are used.

The international research ...

An optical fiber about the thickness of a human hair can now carry the equivalent of more than 10 million fast home internet connections running at full capacity.

A team of Japanese, Australian, Dutch, and Italian researchers has set a new speed record for an industry standard optical fiber, achieving 1.7 Petabits over a 67km length of fiber. The fiber, which contains 19 cores that can each carry a signal, meets the global standards for fiber size, ensuring that it can be adopted without massive infrastructure change. And it uses less digital processing, greatly reducing the power required per bit transmitted.

Macquarie University researchers supported the invention by developing a 3D laser-printed glass chip that allows low loss acce...

An optical fiber that uses the mathematical concept of topology to remain robust, thereby guaranteeing the high-speed transfer of information, has been created by physicists.

Optical fibres are the backbone of our modern information networks. From long-range communication over the internet to high-speed information transfer within data centres and stock exchanges, optical fibre remains critical in our globalised world.

Fibre networks are not, however, structurally perfect, and information transfer can be compromised when things go wrong...

The secret to building superconducting quantum computers with massive processing power may be an ordinary telecommunications technology – optical fiber.

Physicists at the National Institute of Standards and Technology (NIST) have measured and controlled a superconducting quantum bit (qubit) using light-conducting fiber instead of metal electrical wires, paving the way to packing a million qubits into a quantum computer rather than ...
