Which of the following descriptions about solving the system OSNR limitation problem is correct? (Multiple choice)
The correct answer is A. Use the coherent reception where the local oscillator laser of the same frequency interferes with the D. Adopt advanced modulation and coding technology to reduce baud rate and improve OSNR tolerance. See the full explanation below for the reasoning.
