摘要
基于三只参数相近的半导体激光器及单一光纤信道仿真并实验实现了全双工混沌激光保密通信。当两端发送的数据速率均为1.25 Gb/s时,在一条标准单模光纤中全双工保密传输距离达25 km,正反向恢复数据的Q因子分别为2.1和2.0。该方案大幅度节省了光纤链路和设备、降低了实现成本,提高了数据传输的保密安全性。
Abstract
The full duplex chaotic optical secure communication is simulated and experimentally realized based on three similar parameter semiconductor lasers and a single fiber channel. Two oppositely transmitted data streams with bit rates of 1.25 Gb/s can be encrypted and decrypted successfully between two communication terminals over a 25-km single mode fiber channel. The Q-factor values of recovered data in forward and backward transmission are 2.1 and 2.0, respectively. The proposed scheme largely saves optical fiber link and devices, reduces the cost of implementation, and improves the security of data transmission.
