    I’m sorry if I made the false impression that I know what I’m talking about. I’m just discussing and learning as I go. But I went back to the article and looked for the specific figures, and you were right, they are amplifying 1550-nm wavelength, which is NIR. And average glass is usually opaque to wavelength at around 2500nm, so it shouldn’t get blocked. At least not much.
