Which of the following descriptions about solving the system OSNR limitation problem are correct? (Multiple choice)
The correct answer is A. Use advanced modulation and coding technology to reduce the baud rate and improve OSNR B. Use the local oscillator laser of the same frequency to interfere with the received optical signal to D. Use low noise figure NF, high performance EDFA and Ramani amplifier board, such as. See the full explanation below for the reasoning.
