Influence of the incident polarization state drifting off TE mode on composite second order distortion (CSO) and composite triple beat distortion (CTB) of an optical fiber AM CATV externally modulated transmitter is analysed theoretically.

• 从理论上分析了入射到调制器的偏振态偏离TE模时对外调制光发射机组合二次失真（CSO）和组合三次差拍（CTB）的影响。
