On November 11, China Mobile announced that it had partnered with industry collaborators to achieve real-time transmission of a single-wavelength 1.6Tb/s signal over long-haul G.652.D backbone optical fiber, leveraging 230GBaud key technology. This milestone set a new record for the longest 960 km single-wavelength 1.6T transmission and marked a significant step forward in advancing the performance of 1.6T optical transmission systems. Driven by the explosive growth of AI technologies and applications, T-bit-level high-speed transmission technology for intelligent computing center interconnection is accelerating its evolution. As the next-generation rate target following 400G, 1.6T has gained industry consensus within standards organizations such as ITU-T and OIF.
