Which of the following statements about EDFA is false?

Question

Vladimir Litvinenko · Accepted Answer

1510nm optical monitoring channel can be effectively amplified by EDFA

Vladimir Litvinenko · Answer

The amplification of optical signal by EDFA is pure optical amplification, no need for photoelectric conversion

Vladimir Litvinenko · Answer

Noise figure, saturated output power, gain flatness, gain, etc. are all important parameters to characterize EDFA

Vladimir Litvinenko · Answer

When the output power of the EDFA reaches saturation, increase the input optical power, and the gain of the EDFA will decrease.
