摘　　要：在特定水声应用环境中需要双向传输高低压复合信号。传统基于同轴电缆的传输方法信号频分耦合网络复杂,工作时误码率高,可靠性较差。为此,提出了一种新的光电一体化复合水声信号传输体制,采用光电混合缆进行传输。文章对涉及的关键技术进行介绍,同时基于Manchester编码技术,初步对大容量数据的时分双向稳定传输进行实验,验证了光纤传输多路水声复合信号的可行性。In a specific environment,signals that consist of high-voltage and low-voltage should be transmit through a coaxial cable. Because of the compound signal, the frequency division coupled network of the conventional transmission method is so complicated that the system has a high bit error rate and low reliability. In order to solve these problem, a new transmission method based on optical power composite cable has been proposed. This paper analyzes and elaborates some key technologies involved in the process. Based on the Manchester coding and decoding technique, the time-multiplexed bidirectional transmission of the large-capacity data is preliminary finished. Also, through experiment, the feasibility of the multichannel underwater compound signals transmission based on optical fiber has been validated.
