报道了一个140 Mbit/s光DPSK系统实验，该系统采用90 °光混合器实现同相和正交检测。概述了光学混合器的原理，并将偏振失调对光学性能的影响与标准零差/外差检测进行了比较。
A 140 Mbit/s optical DPSK system experiment employing a 90 degree optical hybrid to achieve in-phase and quadrature detection is reported. The principle of the optical hybrid is outlined and the effect of polarisation misalignment on the optical performance is compared with that for standard homodyne/heterodyne detection.
