Question 287

Which of the following is wrong about the comparison between Raman amplifiers and EDFAs?

The Raman amplifier selects different pump sources to amplify signals in different bands, so the Raman amplifier has no gain bandwidth limit in theory, while the EDFA has a range of gain bandwidth

The equivalent noise figure of the Raman amplifier is smaller than that of the EDFA

The gain calculation/testing method of Raman amplifier and EDFA is consistent, both are "gain = output power - input power"

The gain medium of Raman amplifier is transmission fiber: while the gain medium of EDFA is EDF (Erbium Doped Fiber)

Question 290

Which of the following descriptions about the Optix OSN 9800 subrack are correct?

When the OSN 9800 P18 is used as the slave subrack, the IU18 slot can only be inserted into the service board

When the OSN 9800 universal platform subrack is used as the slave subrack, the main control board must be placed

In the OSN 9800 U32 subrack, IU70 is the active CTU and IU78 is the standby CTU

The OSN 9800 U16 subrack has a total of 16 service slots, these slots have the same capacity, and the maximum support single slot 400bit/s ODUK crossover
