When the OSN 8800 needs to access GE signals, the boards that can be used are: (Multiple Choice)

Which of the following description are wrong about the path method to create a Client path?

A.If the route to be automatically calculated is different from the planned path, you can set the "constrained node" or "must pass through the node" to perform routing constraints.
B.Create a client service path by using the path method. After the creation, the optical layer OCh path is automatically generated to reduce the secondary teaching of the path creation.
C.The creation or search of a new path must be possible if its upper service layer path already exists.
D.Select the "Activate" checkbox. After the path is successfully created, it will be delivered to the NE layer. Otherwise, the path configuration text will only be saved on the network management side.

Which of the following description of the PM_BIP8 related alarm is correct?

A.The PM_BIP8_DEG alarm indicates the PM segment signal degradation alarm in the ODU layer.
B.The PM_BIP8_SD alarm indicates the PM segment signal degradation alarm in the OTU layer.
C.The PM_BIP8_OVER alarm indicates that PM error amount has exceeded in the ODU layer.

Which of the following are not part of the 400G originating modulation technology?

Which of the following statements about the line fiber quality monitoring performance parameters is wrong?

A.The total fiber loss will affect the detection distance and the dynamic range is fixed for the same detection mode. Therefore, a larger total fiber loss indicates a smaller detection distance.
B.Measurement is performed multiple times within the detection time. The average value is obtained based on the measurement results to improve the measurement precision. The actual duration from the time when a detection event starts to the time when the detection results are returned will be longer than the Detection time.
C.The pulse width of emitted optical pulses varies according to monitoring modes, and affects the detection distance and measurement precision. A greater pulse width provides a larger dynamic range, longer detection distance and better measurement precision.
D.When the pulse width increases, the light emitting time increases and consequently a larger energy is obtained. This means that a larger dynamic range can be acquired but also larger dead zones will result.
