摘 要: 文章比较了两种在自适应偏振模色散(PMD)补偿设备中控制信号的控制方法,即前馈(FeedForward)检测控制和反馈(Feedback)检测控制;分析比较了各种可用作控制的信号,包括偏振度(DOP)、信号频率分量、眼开代价、两正交主极态(PSP)上光信号分量间的相位差和副载波信号等。 We compared feed forward and feedback as control mechanisms in adaptive polarization mode dispersion compensators(APMDC) ; Different signals work as control input of APMDC, such as degree of polarization, spectral frequency component, eye-opening penalty, phase difference between frequency components on the orthogonal principal states of polarization, subcarrier tone added to data, are also analyzed and compared.
