At the 2026 Global Optical Fiber and Cable Conference, the world's first international standard for multicore fiber was officially released, jointly drafted by FiberHome, Hengtong Optic-Electric, ZTT, Yongding, Far East Communication, and Shanghai University. The standard specifies technical conditions for multicore fiber geometry, transmission characteristics, mechanical and environmental performance, promoting weak-coupling multicore fiber from laboratory trials to large-scale commercial use.
