摘　　要：CMI(coded mark inversion,传号反转码)码是数字光纤通信传输码型中的一种。介绍了CMI的编译码原理,并用Pro-tel99软件对CMI码的编译码进行了电路设计,在此基础上用Multisim8软件做了仿真。CMI code is one code of digital fiber communication transmission system. Here, the principles of CMI＇s encoding and decoding is introduced, and designed a circuit to realize the function mentioned above with the help of Prote199 software. Based on the circuit, simulations were done with the help of Multisim8 software.
