Recently, China Mobile Communications Group Hunan Co., Ltd. (China Mobile Hunan) and Huawei jointly built the first 400G all-optical transport network in central China. They achieved this feat by deploying cutting-edge solutions such as ultra-high-speed 400G, all-optical cross-connect (OXC), automatically switched optical network (ASON), and iMaster NCE. The project aims to build a high-bandwidth, low-latency, highly reliable, flexible and agile all-optical bearing and grooming premium network throughout Hunan province, with the Changsha-Zhuzhou-Xiangtan City Group as the core. Its primary purpose is to contribute to the digital and intelligent development of the province.
