New fibre optic data transmission speed record of 450Tbps (ucl.ac.uk)

Researchers led by UCL have set a new fibre optic transmission record of 450 terabits per second over an existing, commercially installed optical fibre link between London data infrastructure. The result uses additional wavelength bands beyond the standard C- and L-bands to expand the number of channels, with the team sending data over a 39-kilometre round trip. While it is not expected to change home internet speeds soon, the work is positioned as a proof of concept for upgrading capacity between data centres, with possible commercial adoption in several years.
