| Abstract: |
| The principle of digital optical translator
and receiver is introduced and the design of multiplexing and demultiplexing i
s accomplished wi
th the insystem 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. |
| Key words: optical communication digital multiplexing and de-multiplexing digital optical translator and r
