1. Regarding the M40 and D40 channel isolation indicators of OSN 8800/6800 devices, which of the following statements is correct? () (multiple choice)

A) M40 adjacent channel isolation> 22dB
B) The isolation of SFIU's LINE1-OSC1 and LINE1-OSC2 are both ≥65db
C) FIU's IN-TM and IN-TC isolation are both >40db
D) D40 non-adjacent channel isolation> 25dB
E) M40 non-adjacent channel isolation> 25dB
F) D40 adjacent channel isolation> 22dB

2. In the network management planning process, which item is not completely necessary?

A) Network management software/hardware configuration
B) Network scale planning, network management deployment planning
C) Network parameter planning and reliability planning of the network management server
D) DON network planning, OSS connection planning

3. The SNCP ring network composed of OptiX OSN 3500 equipment uses GXCSA as the cross-connect board, and the main ring is equipped with an SL64 single board. A and B are two adjacent nodes.
The station B receives a large number of errors in the regeneration section and multiplex section on the SL64 board of station A.
At the same time, station A receives the remote error code of the multiplex section reported on the SL64 board of station E.
In the networking diagram, it is found that the distance between A and B is 100km, the rate is 10G, and the configuration structure is "light board + BA + PA + DCU + light board".
Which of the following causes the error code to occur? (multiple choice)

A) Insufficient BA+PA gain leads to bit errors
B) Error code caused by light board failure
C) Cross-board and circuit board coordination problems cause bit errors
D) DCU module model error

4. The following about system OSNR commissioning errors are

A) Adjust the single-wave flatness first, and then adjust the optical power of the main line
B) The multiplexer is an M40V single board, "watching the receiving end, modulating the end", while ensuring that the optical power flatness meets the index requirements, the optical power flatness can be sacrificed to ensure the flatness of the OSNR (or BER)
C) One of the principles of the OSNR flatness commissioning of the MPI-R point system: After the pump power is determined, the OSNR flatness of the MPI-R point is detected by a spectrometer, if the OSNR flatness is not up to standard (OSNR flatness index ≤ 2dB) , You need to adjust M40V
D) APE automatically adjusts the optical power of each channel to ensure that the optical power of the receiving end is flat, thereby ensuring a flat OSNR

5. Regarding the configuration description of the U2000 northbound CORBA interface, what is wrong is

A) The default port numbers of normal mode and SSL mode in the basic configuration of U2000 CORBA are different
B) Set the host address, enter the host name or IP address according to the network management plan and design. The "host" mentioned here refers to the computer that provides CORBA services
C) The U2000 northbound CORBA interface and the U2000 server run on the same machine, and the machine configuration is required to be able to install and run the U2000 server, and no additional hardware configuration is required
D) In the U2000 CORBA configuration, at least one of the filtering virtual network element switch and virtual network element switch must be configured
