Design of Secondary Multiplexing and De-multiplexing of Digital Optical Translator and Receiver

The principle of digital optical translator and receiver is introduced and the design of multiplexing and de-multiplexing 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 multiplexing and de-multiplexing are emphasized.A method of secondary synchronous multiplexing by byte is provided 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.
