AVERAGE LENGTH MAGNITUDE DETECTING APPARATUS, AND METHOD |
摘要 |
The present invention relates to an average length magnitude detecting apparatus and method, and an optical coherent receiver. The average length magnitude detecting method is adopted for detecting whether an average length of an averager used by a polarization crosstalk canceling apparatus in a receiver is long or short, comprising: determining a magnitude of a residual polarization crosstalk coefficient of the receiver; and determining an index that indicates whether the average length of the averager is long or short according to the determined magnitude of the residual polarization crosstalk coefficient.
