China Mobile and partners used 230GBaud technology to complete a real-time
single‑wavelength 1.6Tb/s transmission over G.652.D backbone fiber, setting a
record 960km single‑wave 1.6Tb/s distance. The trial advances 1.6Tb/s optical
transmission system performance and underlines accelerated evolution of
Tbps‑class interconnects for smart-computing centers driven by AI demand.
1.6Tb/s is positioned as the post‑400G next‑generation rate and has reached
industry consensus in standards bodies including ITU‑T and OIF.
