20世纪中后期,光通信技术的发展使光缆成为海底通信主角,海底不再平静。最近几年,随着全球经济一体化进程的加快和各国间信息交流需求的迅猛增长,海底光缆的铺设成为各国广泛关注、各大电信公司竞相角逐的焦点。海底光缆通信之所以能得到如此迅速的发展,主要有以下几方面原因:全球呈现的信息一体化趋势使各国间的通信和信息流量激增,为海底光缆通信提供了广阔的市场空间;Inter-net和多媒体通信的崛起对各国间的通信带宽提出了更大的需求,这给海底光缆发展带来了新机遇,也对海底光缆通信提出了巨大的需求;
In the middle and late 20th century, the development of optical communication technology made optical fiber cable the protagonist of submarine communications and the seabed was no longer calm. In recent years, with the acceleration of the global economic integration process and the rapid growth in the demand for information exchange among countries, the laying of submarine optical cables has become the focus of attention of all countries and the competition among major telecommunications companies. The reason why submarine fiber-optic cable communications can be developed so rapidly is due to the following reasons: The global trend of information integration has led to a surge in communications and information flows among countries, providing a vast market space for submarine fiber-optic cable communications; Inter-net The rise of multimedia communications has placed greater demands on the communication bandwidth among countries. This has brought new opportunities for the development of submarine cable, and has also placed great demands on submarine cable communications.
