CAICT's Ao Li: AI Computing Drives Evolution of Optical Communication Technology
Start here
On October 19, 2026, Ao Li, deputy director of the China Academy of Information and Communications Technology (CAICT), analyzed the evolution of optical communications driven by AI computing. He said the optical communication industry is shifting from being driven by traditional telecom to being driven by AI computing, with next-generation communication networks and optical communication networks evolving in tandem. On the technology front, 1.6T is at the early commercialization stage globally; hollow-core fiber has been applied to low-latency dedicated lines and cross-domain computing interconnection scenarios; and multi-core fiber is entering high-density data center cable scenarios. On future architecture, Ao Li said optical circuit switching systems will form an optoelectronic hybrid architecture with electrical switching, while the relevant technology roadmaps are still developing in parallel.
