Submarine optical cables are the main medium for submarine communications, connect all continents of the world, and become an important transmission medium for international communications and the realization of transoceanic links. It has the char- acteristics of stable transmission line, low attenuation, wide bandwidth, large capacity-, long relay distance, good confidentiality-, light weight, small outer diameter and so on. The intercontinental communication traffic has been increasing year by year, and has exceed- ed the traffic volume of satellite communication. To become the mainstay of modern intercontinental communications. Based on the databases of CPtlSABS and DWPI, and through the collection, indexing and combing of patent documents, this paper takes the patent application of submarine optical cable as the object of analysis, analyzes the application situation, the country of application, the dis- tribution of technology and the route of technology- development in this field, which is based on the databases of CPRSABS and DW- PI to provide a reference for the development of the industry.
