Which of the following statements about a TNG2WSMD09 board aretrue? (Choose all that apply.)

• A.It implements optical-layer service grooming for multiple wavelengths.
• B.It is a reconfigurable optical add/drop multiplexing unit.
• C.It is a 9-port wavelength selective multiplexer/demultiplexer board (Super C band).
• D.It supports optical power adjustment and online optical power detection.

In the OTUk frame structure, which of the following alarms are related to section monitoring? (Choose all that apply.)

• A.OTUk_SM_DEG
• B.OTUk_SM_BDI
• C.OTUk_DEG
• D.OTUk_BDI

If the intermediate flatness method is used, the objective of single-wavelength optical power adjustment at the transmit and receive ends is to ensure that the flatness of the single-wavelength input optical power is within the range of the nominal single-wavelength input optical power ( ).

• A.±3 dB
• B.±1 dB
• C.±2 dB
• D.±4dB

WDM systems generally use DCMs to compensate for chromatic dispersion. Which of the following statements about DCM-based dispersion compensation is false?

• A.If the DCM configuration is false, the receive-end performance will deteriorate.
• B.If the DCM configuration is incorrect, the system OSNR will deteriorate.
• C.Compared with line transmission optical fibers, DCMs are prone to non-linear effects. Therefore, the incident optical power of the DCMs must be controlled.
• D.For a 10G system with a fiber length shorter than 400 km, G.652-specific DCMs can be used to compensate for dispersion in G.655 (Leaf) optical fibers.

After GE services enter the client side of an OUT board that supports Ethernet services, they are encapsulated into OTN or SDH signals by the signal processing module. The alarm signals are processed in the same way between encapsulation into OTN signals and encapsulation into SDH signals.

• A.TRUE
• B.FALSE
