摘要 提出了一种利用相位调制器实现一阶边带抑制的光标记交换(OLS)技术的新方案,在中心载波和其余生成的多个副边带分别进行强度调制,实验产生10Gb/s非归零(NRZ)光载荷和2.5Gb/s垂直频分复用(OFDM)光标记信号,并分别在单模光纤中传输了50km。分析了基本原理,进而建立了一简单的系统理论模型,最后通过仿真和实验相结合的方法验证了方案的可行性。 A new scheme of the first-order carrier suppress optical label switching technology is proposed using phase modulator.Amplitude modulation is employed in generating central optical carrier and other order carriers.The 10 Gb/s none-return-zero signal and 2.5 Gb/s optical OFDM label are generated.The feasibility of the new scheme has been demonstrated by both simulation and experiment.
