海底光缆工程发展20年

对全球第一条海底光缆问世后20年来海底光缆工程发展的历程作了简要回顾。随着光纤传输技术的不断进步,海底光缆的通信技术得到了飞速发展,近20年来,其商用系统已经历了四代。海底光缆工程发展的重要标志,还体现在海底光缆施工技术的日趋完善,水下定位、海底数字式高分辨率的地球物理探测、海底原位测试等高新技术在海缆路由调查与埋设评价调查中的广泛应用。此外,对海底光缆市场与行业结构所经历的深刻变化作了分析,并预测了国际海底光缆网络的发展和市场前景。

Development of submarine optic cable engineering in the past twenty years

This paper has reviewed the development of submarine optic cable engineering in the past twenty years since first submarine optic cable construction.With the progress of transmission technology,the communication technology of submarine optic cable has been made a great headway.In the past twenty years,the commercialization system has gone through four generations.Important marks of development of the submarine optic cable engineering are embodied also in perfecting for the construction technology and in applications of high and new technology,such as underwater positioning,high resolution digital geophysical survey,in situ seabed measurement et al.,which are for the use of submarine cable route survey and burial assessment survey.This paper also analyzed the main deep variations on the business and the market of submarine cable line and forecasted international submarine optic cable net development and the market prospecting.
