When configuring 1+1 optical line protection, you can select RI1/TO1 or RI2/TO2 as the working channel based on our given context.

• A.FALSE
• B.TRUE

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.FALSE
• B.TRUE

If a DCM is configured in a system, the input single-wavelength optical power of the DCM must be lower than or equal to ( ) dBm.

• A.-1
• B.-4
• C.-3
• D.-2

Optical power is an Important indicator of a WDM system and directly affects the transmission distance of signals. Therefore, the output optical power of a site must be as high as possible to ensure that signals can reach the peer site.

• A.FALSE
• B.TRUE

Which of the following are basic principles for locating a WDM system fault? (Choose all that apply.)

• A.You should check for external faults before internal faults.
• B.You should check networks before NEs.
• C.You should check single-wavelength services before multi-wavelength services.
• D.You should check bidirectional transmission before unidirectional transmission.
