Which of the following statements about solving the system OSNR limitation problem is correct? (Multiple choice)
The correct answer is A. Use advanced modulation and coding technology to reduce baud rate and improve OSNR tolerance. B. Coherent reception using local oscillator lasers of the same frequency to interfere with the received D. Use low noise figure NF, high performance EDFA and Ramani amplifier board as follows N13OAU106 or. See the full explanation below for the reasoning.
