What should I pay attention to when commissioning a 100G and 10G hybrid transmission system? (Multiple Choice)

• A.In order to accurately measure the optical power of 100G wavelength, it must be debugged using a spectrum analyzer or a MAC card.
• B.Pay attention to the mixed spectrum. The spectrum of the 100G signal is wider and looks lower than the 100G signal in the spectrum, but the actual optical power is equivalent.
• C.For a hybrid transmission system with dispersion compensation, the dispersion compensation requirements are consistent with the requirements in a 10G non-coherent system.
• D.The optical power of the 100G signal is recommended to be higher than the optical power of the 10G signal, but not higher than the single-wave nominal value of the optical panel.

Which of the following statement is correct?

• A.The optical layer path and the electrical layer path are independent. It is not necessary to delete the electrical layer path when deleting the optical layer path.
• B.Deactivation will delete the configuration of the U2000, which has no impact on the device side services.
• C.The optical layer path must be deleted first when the electrical layer path is removed.
• D.When the OCh path exists, you can directly create a client path. The NMS automatically creates an ODUk path.
