首次构造并实验验证了一个允许双向信息传输的光纤混沌通信系统。利用两台半导体激光器的同步混沌输出作为通信载波，在10 km单模光纤信道上，两个通信终端之间可以对两个反向传输的高频模拟信息（3GHz和4GHz）进行加密和解密。此外，具有2.5Gb/s的比特率的两个数据流也可以以低于10-4的估计的比特错误率被双向加密和解密。
A fiber-optic chaos communication system for allowing bidirectional message transmission is first constructed and experimentally demonstrated. Using the synchronized chaos outputs of two authorized semiconductor lasers as communication carriers, two oppositely transmitted high frequency analog messages (3 and 4 GHz) can be encrypted and decrypted between two communication terminals over a 10-km single mode fiber channel. Furthermore, two data streams with bit rates of 2.5 Gb/s can also be bidirectionally encrypted and decrypted with bit-error-rates estimated below 10-4.
