H12-931-ENU Exam Question 6

The ODU product label is shown in the picture. Which of the following statements is correct? (multiple choice).

A.The receiving frequency range is: 7582-7638MHz

B.The transceiver interval of this ODU is 154MHz

C.The transmitting frequency of this ODU is located in sub-band A of 7GHz

D.This ODU can be used as low station

H12-931-ENU Exam Question 7

Which of the following descriptions are correct for error alarms (multiple choice)

A.OTUk_ES (OTUk_BEE ), ODUk_PM_ES (ODUk PM_BBE) are OTUk/ODUk errored seconds (background error block), the count is the error count of the OTUk/ODUk signal that is counted, non-zero means OTUk/ODUk signal The second in which a bit error occurred (the number of errored blocks).

B.FEC_BEF_COR_ER enables the FEC function to be effective, FEC error rate before error correction, indicating the error statistics of the received OTUk signal (including OTUk overhead), and the error rate before error is not zero, indicating the error rate introduced by the transport layer The bit error may have affected the OTUk signal.

C.FEC_AFT_COR_ER enables the FEC function to be valid. The error rate after FEC error correction indicates the error statistics of the OTUk signal (including OTUk overhead) after FEC encoding and error correction. The error after correction is not zero, which means transmission The bit error introduced by the layer may have affected the OTUk signal.

D.OTUk_SES and ODUk_PM_SES are OTUk/ODUk severely errored seconds, and the count is not zero, indicating that the OTUk/ODUk signal has generated a large bit error in seconds (1 second counting error bits more than 15% of the maximum transmission byte)

H12-931-ENU Exam Question 8

The TN13FIU board does not support optical power detection, but supports reporting MUT_LOS alarms through alarm synthesis

A.TRUE

B.FALSE

H12-931-ENU Exam Question 9

For WDM networks, the following descriptions are correct

A.For OAU boards, you can roughly judge the type of DCM module connected to the site according to the upper threshold of nominal gain (dB) on the network management system-the upper threshold of actual gain (dB)

B.For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 10G

C.For OAU boards, the type of DCM module connected on site can be roughly judged based on the difference between the output of POUT and the input of BAIN

D.For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 100G

H12-931-ENU Exam Question 10

Throughput refers to the maximum rate of the network without frame loss. During the test, the test starts from the maximum line rate frame rate Xmax that the device can support. When the device starts to lose frames, reduce the frame rate. When the device does not lose frames Time, increase the frame rate
