The single wavelength incident optical power of a 100G system is lower than that of a 10G system. When
100G channels are expanded In a 10G system, the OA gain can be reduced to decrease the single-wavelength output optical power of the OA to meet the incident optical power requirements.

• A.FALSE
• B.TRUE

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.

The OptiXtrans DC908 chassis can be a DC chassis or an AC chassis.

• A.FALSE
• B.TRUE

Which of the following statements about OTN frame structure overheads is false?

• A.The value of FAS changes dynamically with different signals.
• B.The FAS is not scrambled.
• C.The FAS is located at the start position of the OTN frame structure.
• D.OTUk_LOF is generated when FAS framing fails.

The DM function can be used to measure the delay and jitter of service packets.

• A.FALSE
• B.TRUE
