Marine Optical Cable: Technology and Maintenance of Underwater Communication Backbone
Marine optical cables are the core of cross-sea and offshore communication, undertaking the task of transmitting data between continents and connecting offshore oil platforms, islands, and other remote areas. Compared with land optical cables, marine optical cables face more severe challenges, such as deep-sea pressure, seawater corrosion, marine organism damage, and ship anchoring risks. Therefore, marine optical cables have higher requirements for structural design and material selection.
The structural design of marine optical cables usually includes a central strength member, fiber core, water-blocking layer, armor layer, and outer sheath. The armor layer, made of high-strength steel wire, can resist deep-sea pressure and external impacts; the outer sheath is made of corrosion-resistant materials to prevent seawater erosion. The installation of marine optical cables requires professional equipment and technology, such as cable-laying ships and underwater robots, to ensure that the cables are laid smoothly and avoid damage. In terms of maintenance, real-time monitoring systems are used to detect faults such as cable breaks. Once a fault occurs, professional salvage and repair teams are dispatched to carry out emergency repairs, which is costly and time-consuming.
Marine optical cables are an important part of the global communication network. Improving their technology and maintenance capabilities is crucial for ensuring the stability of cross-sea communication and promoting the development of marine resources.
