Question 292

Which of the following descriptions about optical power commissioning is wrong?

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.

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

The single-wave optical power at the receiving end can be calculated accurately according to the total power

Too high optical power will cause nonlinear effects. The lower the optical power into the fiber, the smaller the nonlinear effects.

Question 293

Which of the following descriptions about EDFA is wrong?

When the output power of the EDFA reaches saturation, increase the input optical power, and the gain of the EDFA will decrease

The optical monitoring channel of 1510nm can be effectively amplified by EDFA

Noise figure, saturated output power, gain flatness, gain, etc. are all important parameters to characterize EDFA

The amplification of optical signals by EDFA is pure optical amplification without photoelectric conversion.

Question 295

Which of the following descriptions about single-site commissioning is wrong?

After the hardware inspection of the single station is completed, make sure that all power switches are in the off position

It is strictly forbidden to plug and unplug the power plug and PIU single board while electrified

In the case of power failure, you can contact the board without wearing an anti-static wrist or antistatic gloves

If the input voltage of the equipment is not within the required range, a rectification suggestion should be put forward, and power-on is strictly prohibited

Question 296

When manually configuring network element data, you need to add a single board to the network element board bitmap. Adding a single board can add a physical single board that is actually in place on the network element, but cannot add a logical single board that does not exist on the actual device.
