The team is now setting its sights on quadrupling this performance to reach an unprecedented 1TB/s.
eeNews Europereports that the researchers used a stimulated Brillouin scattering laser to generate signals at 300GHz for6Gnetworks.
This laser employs interactions between sound and light waves to produce a precise signal.
However, this method becomes highly sensitive to noise when operating at the top end of these frequencies.
For efficient functioning, multi-level signal modulation relies on precise reference signals.
When these signals start to shift, phase noise negatively impacts the performance of the multi-level signal modulation.
This is the highest transmission rate obtained so far in the world using online DSP."
