新型改进光双二进制传输的编解码方案 提出了改进型光双二进制信号在高速率(≥10Gbit／s)传输时预编码的一种新方案。通过分析编解码过 程，证明该信号传输时不易受码间干扰影响，能用二进制强度调制一直接检测的系统接收信号。仿真产生了该信 号的2种码型。结果表明，采用色散补偿技术能使MD NRZ和MD．RZ信号在长距离传输后克服眼图失真，MD-RZ 信号比MD．NRZ信号在传输后有更低的误码率。(Abstract：Anovel pre-coding schemeformodified optical duobinary signalswasproposed．It couldbe applied to缸ansmit high speed data mte signals(≥ 10Gbit／s)．Through analyzing the process of coding and decoding，It Was demonstrated thatmodified opticalduobinary sign alshave capabilityin reductionofpulse—to-pulseinteraction ， and couldbe di． recaymeasured through aconventionalbinaryintensitymodulationdirectdetection(IM—DD)receiver．Twomodified optical duobinary sign als’formats were simulated to generate．Sim ulation results show that MD．NRZ and MD-RZ signals’ formats Can avoid the eye diagrams’distortion for long—distance transmission，if the dispersion Can be compe nsated in each amplifier span．Moreover,theMD-RZ signalhaslowerBER than theIVID-NRZ signal afterlong-distance comm．unication．)
