海底光缆系统因其容量增加很多,比起利用早期技术的系统来说,己显示出了一些值得注意的优点;此外,看来还可能会有一些更显著的优点。本文评述了目前的海底系统技术,接着讨论了继续对光纤和器件工艺进行深入研究而可能达到的结果,同时预测了至少到本世纪末每个阶段成本将进一步显著降低的情况以及无中继光缆长度和线路码速将进一步显著增加的情况。 Submarine cable systems, because of their increased capacity, have shown some noteworthy advantages over systems that utilize earlier technologies; in addition, it seems likely that there will be some more significant advantages. This paper reviews current seafloor system technologies and then discusses possible outcomes that continue to be explored in depth for fiber and device processes while predicting further significant cost reductions at each stage at least by the end of the century and the absence of repeater cable lengths And the line code rate will be further significantly increased.
