提出了采用直接调制激光器传输10 Gb/S光纤,通过电子预补偿避免了线内色散补偿。为了将这种电子色散预补偿技术应用于直接数字激光系统,提出了一种基于人工神经网络的新方法。在实验室实验中实现了190公里标准单模光纤的传输。仿真结果表明,最大补偿距离可达350公里。
We present 10-Gb/s transmission with a directly modulated laser (DML) avoiding inline dispersion compensating by electronic precompensation. To apply this technique of electronic dispersion precompensation to DMLs, a new approach based on artificial neural networks will be introduced. We realized a transmission of 190-km standard single-mode fiber in a laboratory experiment. Simulations show that compensation of up to 350 km can be achieved.
