When debugging the WDM system, it is mainly to ensure the flatness of the power at the end and the flatness of the signal-to-noise ratio.

• A.False
• B.True

The signal-to-noise ratio of the post-wave test on the D40 board with the spectrum analyzer will be larger than the signal-to-noise ratio of the IN port test.

• A.False
• B.True

Which of the following situations do I need to use OSC in a wavelength division system? (multiple choice)

• A.Single span loss exceeds 52dB
• B.Requires OTN optical layer overhead
• C.Using OLA sites
• D.Need to configure business phone

The OptiX OSN 6800 subrack supports 7 sets of dual slots: IU1 and IU2, IU3 and IU4, IU5 and IU6, IU7 and IU8, IU11 and IU12, IU13 and IU14, IU15 and IU16. The configurable electrical layer service between the dual slots is the GE/Any/ODU1 signal. You do not need to configure an XCS board to schedule the electrical layer service in the dual slot.

• A.False
• B.True

Regardless of the aggregation type or non-aggregation type OTU, the SDH signal R_LOS received by the client side is processed on the wavelength division side of the OTU board, and the REM_SF alarm is generated on the downstream client side.

• A.False
• B.True
