摘　　要：本文提出了一种利用扫频本地光源(LO)对光谱幅度码(SAC)标记进行相干探测识别的新型SAC标记交换系统,并利用仿真对所提方案进行了性能验证。首先,阐述了相干探测识别SAC标记的基本原理。随后,利用仿真软件,搭建扫频LO实现SAC标记相干检测的仿真系统模型。最后,通过仿真验证与结果分析,说明了所提方案的工作性能。结果表明:使用扫频相干探测法可以正确识别156Mb/s的SAC标记;当光带通滤波器(OBPF)带宽为60GHz时,净荷信号可实现最佳接收。此时对应系统接收灵敏度为-17.6d Bm。A novel coherent detected spectral amplitude codes (SAC) label switching system with a frequency swept local oscillator (LO) is proposed, and performance of the proposal is verified by computer simulation. Firstly, principle of coherent detected spectral amplitude codes label is described. Then, simulation setup of coherent detected SAC label switching system with the frequency swept LO is built up. At last, analysis on simulation results and conclusions are given. The simulation results indicate that 156 Mb/s SAC labels could be correctly recognized by frequency swept coherent detection; the payload signal reaches optimal performance with 60 GHz bandwidth optical bandpass filter (OBPF), and sensibility of this system is -17.6 dBm.
