CAR is deployed on PTN equipment. Which of the following descriptions is wrong?

A.

The value of PIR is required to be greater than or equal to CIR

B.

The unit of CBS/PBS is Bytes

C.

CBS bursts are marked in yellow

D.

Supports setting the processing mode for CAR-processed packets

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

A.

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.

B.

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

C.

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

D.

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