摘　　要：为了更好地防护光网络,对波长阻断型可重构光分插复用器(WB-ROADM)中衰减余量信号可能造成的影响进行研究,指出利用衰减信号进行恢复窃听具有可行性。对衰减余量对上路同频信号造成的串扰程度进行定量分析,并通过仿真验证加以验证,结果皆表明,衰减余量的存在,使得WB-ROADM存在被窃听、传输质量下降的安全风险。In order to protect the optical network more effectively, potential influences caused by residual signal are investigated in Wavelength Blocker-Reconfigurable Optical Add-Drop Multiple- xer（WB-ROADM）. proposed. The cros The feasibility of using attenuation signal to recovery the eavesdropping is stalk extent caused by attenuation margin to same frequency signal of upload tively and simulated. Simulation results show that the existence of attenuation the WB-ROADM potential security risk of being eavesdropped and with re- quality.
