智联深蓝——信息动脉背后的“向海图强”梦

Core Viewpoint - The article highlights the successful development and implementation of the world's first seven-core underwater optical cable, which significantly enhances data transmission capacity and supports the vision of a smart future for marine and urban integration in Zhuhai [4][5][22]. Group 1: Technological Breakthroughs - The seven-core underwater optical cable achieves a transmission capacity of 410.5 Tbit/s, capable of transmitting 4,000 4K movies in one second, setting a new record in underwater communication [4][5]. - The technology utilizes "space division multiplexing," creating seven independent transmission channels within a single fiber, akin to upgrading a rural road to a seven-lane highway [15][18]. - This project has successfully withstood real marine conditions, maintaining stable transmission over a distance of 25 kilometers, showcasing China's advancements in marine communication technology [19][21]. Group 2: Strategic Development - Zhuhai has launched 108 "new marine infrastructure" projects with a total investment exceeding 110 billion yuan, focusing on information, integration, and innovation [36]. - The Southern Marine Laboratory's innovative concept of "underwater data centers based on island corridors" aims to support the construction of a green computing hub in the Guangdong-Hong Kong-Macao Greater Bay Area [38][40]. - The laboratory is also developing a three-dimensional underwater map of Zhuhai, expected to be completed by the end of the year, to aid in planning new infrastructure projects [46][49]. Group 3: Environmental Monitoring and Disaster Prevention - A comprehensive observation system comprising over 30 devices has been established to monitor meteorological, hydrological, and water quality factors in the marine environment, enhancing disaster prevention capabilities [41][44]. - The laboratory is developing intelligent early warning systems for various marine hazards, providing robust technical support for the sustainable development of Zhuhai's marine economy [43][44]. Group 4: Future Applications - The advancements in underwater communication technology are expected to support remote island communities, enabling reliable networks for telemedicine, online education, and smart fisheries [24][25]. - Innovative equipment, such as fiber optic sensors for marine ecological monitoring and autonomous vehicles for complex marine scenarios, are being developed to enhance operational efficiency in marine environments [27][29][30].
