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 i s accomplished wi th the in system programmable technology and field programmable logic array FPG A .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 transm issio n of video,audio,data and network signal is realized. The design has practical s ignification to enhance channel capability and save fiber source.
