Title: Apparatus and method for monitoring change of polarization state resulted from optical link, and optical receiver
Inventor: QI YANHUI
IPC: H04B10/07
Filed: 2020-02-07
Abstract: To provide an apparatus and method for monitoring a change of a polarization state resulted from an optical link, and an optical receiver.SOLUTION: A change of a polarization state resulted from only an optical link, irrelevant to the polarization state of an input signal of the optical link, may be dynamically monitored in real time by obtaining zero frequency channel response matrices at two moments, based on zero frequency response matrices and phase information on a received signal at the two moments and by determining a parameter characterizing a change of a polarization state resulted from the optical link, based on a change matrix. In addition, by using the zero frequency response matrices and the phase information, the response state of the optical link may be completely reflected, and more accurate monitoring results for the polarization state may be obtained. Further, there is no need to add additional hardware and control elements, thereby simplifying the structure and saving cost.SELECTED DRAWING: Figure 1
