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

A.

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

B.

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

C.

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

D.

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