NEW QUESTION 113
Which of the following descriptions about optical power commissioning is wrong?
- A. In the case of ensuring that the optical power flatness meets the index requirements, the optical power flatness can be sacrificed to ensure the signal-to-noise ratio flatness
- B. Too high optical power will cause nonlinear effects. The lower the optical power into the fiber, the smaller the nonlinear effects.
- C. During the commissioning process, it is necessary to pay attention to the range of the spectrum analyzer and the OUT board to avoid damage to the board and the spectrum analyzer due to excessive input optical power.
- D. The single-wave optical power at the receiving end can be calculated accurately according to the total power
Answer: D
