Which of the following are the benefits of polarization multiplexing technology? (Multiple choice)

The correct answer is A. PDM-QPSK technology reduces the optical harmonic width of the optical signal, making 50GHz B. PDM-QPSK modulation code can reduce the line transmission baud rate, greatly reducing the C. The reduction of optical signal spectrum width will reduce the OSNR requirements of the optical. See the full explanation below for the reasoning.
