At the Optinet China Conference 2023, Li Han, director of the Basic Network Technology Research Institute of China Mobile Research Institute, revealed in a speech that China Mobile has confirmed the availability of 400G technology and will launch 400G product procurement at the end of this year to promote 400G into the commercial stage. "It's time for 400G, and the industry is eagerly anticipating it."
In March of this year, China Mobile announced that the 400G QPSK (Quadrature Phase Shift Keying) optical-electrical-optical relay transmission distance has set a new record, achieving a real-time transmission distance of 5616 kilometers on land. The 400G all-optical network technology verified this time is the core technology for the next-generation intergenerational evolution of backbone transport networks.
