Polarization Control Technology: in the system of coherent optical communication, the polarization of the signal light and local-oscillation light is definitely required in the same deviation, so as to achieve a good mixing effect and to improve the quality of the receiving.
I-Polarization Control Technology: ohlelweni lokuxhumana oluhambelanayo, ukukhanya kwesibonakaliso sokukhanyisa nokukhanyisa kwendawo yendawo kuyadingeka ekuphambukeni okufanayo, ukuze kutholakale umphumela omuhle wokuxuba nokuthuthukisa izinga lokuthola.
