For WDM networks, which of the following description is correct?

For WDM networks, which of the following description is correct?
A . For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 100G
B . For OAU boards, you can roughly determine the type of DCM module connected to the site according to the nominal upper gain threshold (dB) on the network management minus the actual upper gain threshold (dB).
C . For OAU boards, you can roughly determine the type of DCM module connected to the site according to the difference between the output of POUT and the input of BAI
E . For 10G and 100G mixed transmission networks, you can judge whether the dispersion compensation is consistent with the design according to the performance of 10G
