Which of the following statements about 100G coherent PDM-QPSK modulation is incorrect?

The essence of QPSK modulation is to reduce the baud rate of the optical signal by half without reducing the line rate by selecting 4 possible values in the phase of the optical field.
The essence of QPSK modulation is to reduce the baud rate of the optical signal by half without reducing the line rate by selecting 4 possible values in the phase of the optical field.
PDM-QPSK technology is the main modulation code technology for 100G transmission, which can reduce the line rate of 112Gb/s to the baud rate of 28Gbaud/s, greatly reducing the loan requirements for (optical) electrical devices.
