China’s Sanan, Tsinghua and China Mobile Claim Micro‑LED Breakthrough That Could Push Short‑Range Optical Links Beyond 10Gb/s

Sanan Optoelectronics, with Tsinghua University and China Mobile, reports a Micro‑LED light source with >7 GHz 3 dB bandwidth and modeled NRZ‑OOK rates above 10 Gb/s, and has begun shipping samples to international customers. The advance, if validated in systems, could open new short‑range optical interconnect and LiFi opportunities, though manufacturing, packaging and ecosystem challenges remain.
