摘要
为了优化光网络中光信号传输质量,文中针对灵活透明的波长交换光网络中传输信号物理损伤问题,将光链路作为控制研究对象,采用控制反馈系统确定光放大器的调节量,进而优化光信噪比和光网络信号传输质量。本文采用Optisystem和MATLAB软件对光链路进行仿真研究,基于控制调整手段优化光网络信号传输质量。仿真结果表明,引入控制技术可以动态优化光信噪比,提高光链路的传输质量。
In order to optimize transmission quality of optical signal in optical network, in this paper, aimed at the physical impairment issue of transmission signal in flexible and transparent wavelength switched optical network, we made optical link as subject to control and research. We adopted control feedback system to confirm the amount of regulation of optical amplifier and then optimized ONSR（Optical Signal Noise Ratio） and the transmission quality of signal in optical network. In this paper,we used softwares such as Optisystem and MATLAB to simulate and research the optical link and optimized transmission quality of signal in optical network based on control adjustment means. The simulation results indicated that introducing control technology can optimize ONSR（Optical Signal Noise Ratio） dynamically and improve the transmission quality of optical link.
