質問 1

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

A. Line fiber quality monitoring function increases the monitoring accuracy by adding the averaged results to the average. The actual time required from the start detection to the software returning the test result will be greater than the "detection time" is set.

B. The total loss of the fiber will affect the actual detection distance. The dynamic range of the same detection mode is fixed. The larger the total loss of the fiber, the smaller the distance that can be detected.

C. Different modes of light pulse width are different in detection, pulse width affects distance accuracy and monitoring distance. The larger the pulse width, the larger the dynamic range, the longer the test distance and the higher the range measurement accuracy.

D. Increasing the pulse width increases the duration of the laser emission, which increases the energy injected, allowing for a larger dynamic range, but an increase in pulse width results in a larger dead zone.

正解: C

質問 2

A. FALSE

B. TRUE

A. FALSE

B. TRUE

正解: B

質問 4

D. MCA8

正解: A,D

質問 5

In the electrical layer overhead processing-sink function, the signal flow is from the OCh to the client direction, the PM ODUkP is detected first, and then the TCM ODUkT is detected.

A. FALSE

B. TRUE

正解: B

質問 6

Which of the following monitoring boards do not support the processing and transparent transmission of 1588V2 signals? (Multiple choice)

A. SC1

B. AST2

C. SC2

D. ST2

正解: A,C

質問 7

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

A. 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.

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. 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.

正解: B

質問 8

For the whole network error test in the commissioning test, which of the following statement is correct? (Multiple choice)

A. The number of OTU boards or tributary boards connected in series for the whole channel error test is recommended to be no more than 13

B. The duration of the full channel error test is 20 hours. If the error occurs within 20 hours, it needs to be retested for 20 hours after troubleshooting.

C. When the single channel error test is performed, the remote end needs to perform hardware loopback on the tributary board client side.

D. To ensure the smooth passage of all channel services across the entire network, a 10-minute error prediction is required for each single channel.

正解: C,D

質問 9

The ways of synchronize alarms are (). (Multiple Choice)

A. Manual synchronization

B. Automatic synchronization

C. Timing synchronization

正解: A,B

質問 12

Which of the following description of the single station commissioning is wrong?

A. Single station hardware check is complete, make sure all power switches are in the off position

B. It is strictly forbidden to plug and unplug the power plug and PIU board.

C. In case of power failure, the contact board can be used without anti-static wrist or anti-static gloves.

D. If the input voltage of the equipment is not within the required range, suggestions for rectification should be proposed.
