摘　　要：介绍了数字光端机的工作原理,利用在线系统可编程技术和现场可编程逻辑阵列FPGA进行复分接设计,包括硬件设计、软件设计和测试。详细介绍了复接和分接,设计一种同步按字节的二次复接方式,实现了视频、音频、数据、网络信号的可靠传输,对提高传输信道容量、节约光纤资源有一定的实用意义。The principle of digital optical translator and receiver is introduced and the design of multiplexing and de-mnltiplexing is accomplished with the in-system programmable technology and field programmable logic array FPGA. The whole design is mainly divided into the hardware design, software design and test. The parts of mul- tiplexing and de - multiplexing are emphasized. A method of secondary synchronous multiplexing by byte is pro- vided and the reliable transmission of video, audio, data and network signal is realized. The design has practical signification to enhance channel capability and save fiber source.
