摘要
对比研究了三种光双二进制码(Optical Duobinary Code,ODC)的发射机结构,并仿真了三种ODC的单信道系统传输性能。仿真结果表明,改进型ODC较普通ODC和滤波成型ODC具有更好的色散及非线性效应抑制能力,该仿真结果为光双二进制码实际应用提供了理论参考。
In the paper, the transmitter structures of three kinds of Optical Duobinary Code (ODC) were compared, and their transmission performance was studied in single channel system. Simulation results show that the modified ODC has better suppression ability of dispersion and nonlinear effect than that of common ODC and filter shaping ODC. The simulation results provide a theoretical reference for the practical ODC application.
