Huawei H31-341 Online Questions & Answers

• Question 51:

  In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites.The OTU at station A accesses four channels of R_LOS signals on the client side. After being processed in the middle part and on the WDM side of the OTU at station A, the alarm signals are then sent to station B. The ODUk_PM_AIS alarm of the corresponding channel is generated in the middle part of station B. The ODUk_PM_AIS alarm is detected in the client device.

  A. True
  B. False
  B. False

• Question 52:

  If no bit error test is performed on a optical channel for 10 minutes, the local end uses the SDH analyzer to connect to the client-side port on the OTU board, the client-side port on the opposite OTU board need to be self-looped by a fiber. In the case of self-loop, a fixed attenuator must be added.

  A. True
  B. False
  A. True

  B. -2dBm
  C. +7dBm
  D. +4dBm
