无中继器海底光波系统连接被大海隔开的两个陆地位置，无需光信号的海底再生。为了实现尽可能长的跨度，该系统将包含高性能光电设备的地面终端与超可靠的海底电缆技术相结合。讨论了用于实现经济高效、大跨度无中继海底光波系统的光波技术。这包括海底光纤和电缆、激光器和接收器以及终端设备。介绍了该技术的首次应用——台湾台南至澎湖系统。研究了增加高容量无中继海底系统最大可达到跨度的可能性。关键要素是更高输出的发射器、更灵敏的接收器和改进的光纤。<<ETX>>
A repeaterless undersea lightwave system connects two terrestrial locations separated by the sea without the need for undersea regeneration of the optical signal. To achieve the longest span length possible, the system combines terrestrial terminals containing superior-performance optoelectronic devices with ultrareliable undersea cable technology. The lightwave technology used to achieve cost-effective, long-span repeaterless undersea lightwave systems is discussed. This includes undersea fiber and cable, lasers and receivers, and terminal equipment. The first application of this technology, Taiwan's Tainan to Peng-Hu system, is described. The possibilities for increasing the maximum attainable span length of high-capacity repeaterless undersea systems are examined. Key elements are higher-output transmitters, more sensitive receivers, and improved optical fibers.<<ETX>>
