Experimental photonic chip completes crazy 44 Terabit speed test

A team of researchers in Australia recorded the fastest speed ever – a staggering 44.244 Terabit (terbit) per second. This is more than 44,000 times faster than the current maximum speed of the civil connection. This incredible feat was achieved by a new optical chip. The key to this breakthrough is a new device called micro-optical communication, which is undergoing its first field test.

The device uses 80 independent infrared lasers, each of which can be used as a separate communication channel. The team, made up of researchers from Monash University, Sweeburn University and the Royal Melbourne Institute of Technology, tested the technology using 76.6km (47.6 miles) of fiber, which was installed between two university campuses in Melbourne, Australia.

At 4THz bandwidth, the network is capable of transmitting data at an astonishing speed of 44.2Tb/s. At present, the most common consumers can use the user terminal the fastest network speed is fiber optic access, the speed of 1Gb/s. ESnet, the U.S. Department of Energy’s dedicated science network, has previously achieved a maximum speed of 400 Gb/s, but it was specifically designed for organizations like NASA.

The results suggest that once photonic chips can be integrated together, they can be expanded relatively easily to public use. “In the long run, we want to create integrated photonic chips that will allow us to achieve this data rate on existing fiber links at minimal cost,” said Arnan Mitchell, lead researcher on the study. “Initially, these technologies will provide the possibility for hyperfast communication between data centers. However, we can imagine that this technology will become so low-cost and compact that it can be deployed for commercial use by the general public in cities around the world. “

The study was published in the journal Nature Communications.
