ISSUE DESCRIPTION


Why can't the incident optical power of coherent 100G single wavelengths be too high?


Please assist me in figuring out the incident optical power of coherent 100G single wavelengths. Thanks in advance!

Hello, @Wassim!


A coherent signal produces more nonlinearity than a non-coherent 10G signal does. The incident optical power of a coherent 100G wavelength must be less than that of a 10G wavelength.


Thanks.

Hello there!


I agree with @wissalw's point of view, he is right.

However, when the incident optical power is low, the transmit distance becomes shorter. Therefore, OA devices need to be added.
