Exame Informática | Researchers break fiber data transmission record: 44.2 Tbps

A ‘traditional’ fiber optic cable that connects the university
Melbourne and the Clayton campus of Monash University
team of researchers passing data at 44.2 Terabits per second, a record
worldwide. In theory, this rhythm allows you to download the contents of 50 discs
Ultra HD Blu-ray with 100 GB each in just one second.

The researchers involved published their findings
at Nature Communications and explain that the cable in question covers 75
kilometers between the two campuses and reflecting the bandwidth infrastructure
broadband used by the Australian National Broadband Network (NBN). The world record
speed has been achieved using a new technology called micro-comb,
that allows a more efficient and compact way for data transmission and that
was used on the ground for the first time.

Professor Arnan Mitchell, from RMIT University,
stresses that “in the long term, we hope to create integrated photonic chips that allow
that this type of transmission rates may be possible through fiber links
existing optics with minimal cost ”.

The work was done by university researchers
from Swinburne, Monash and RMIT, three Australian institutions.

Despite the advance, it is not to be believed that consumers
may have direct access to these speeds in the near future. The
first intervention sites should be connections between servers. After all,
gigabit networks have been a reality for some years and are still rare in use
domestic.
