1. 引言 随着海洋事业的发展,为满足地震、勘探、石油和国防等方面的需要,我国的海底光通信有了长足的进步。 采用水下光缆远距离传输信号,对缆线、供电、敷设、防腐、防潮、环境、容器和系统的可靠性及工艺性都提出了很高的要求。美国、日本、法国、瑞典和芬兰等国家在这些方面取得了较满意的结果。而我国则刚刚起步,还缺乏经验。本文仅就海底光缆远距离传输信号,如何保证中继、终端电源供给,使小继放大器及终端站等有关部件乃至整个系统的可靠运行,作一探讨。
1. Introduction With the development of marine undertakings, China has made great strides in undersea optical communications to meet the needs of earthquakes, exploration, petroleum and national defense. The use of underwater fiber optic cable to transmit signals over long distances poses high demands on the reliability and manufacturability of cables, power supply, laying, corrosion protection, moisture protection, environment, containers and systems. Countries such as the United States, Japan, France, Sweden and Finland achieved more satisfactory results in these areas. Our country has just started, but also lack of experience. In this paper, only the submarine cable long-distance transmission of signals, how to ensure the relay, the terminal power supply, so that the next amplifier and terminal stations and other related components and even the reliable operation of the entire system for a discussion.
