New hollow-core fiber test pushes internet speeds to 1.2Tb/s
China’s hollow-core fiber trial smashes speed records—could redefine AI-era data transmission limits
📍 How it ended
China’s hollow-core fiber trials demonstrated record-breaking speeds of 51 Tb/s over long distances without signal regeneration, marking a major advance in optical networking. A separate test achieved 1.2 Tb/s per-wavelength transmission, though no further updates on commercial deployment or broader adoption followed.
