Jared - " What you can do is transport multiple PONs over a single fiber using CWDM wavelengths. However, you need to do an OEO conversion at the remote side back to standard wavelengths and have separate PON trees for each wavelength." Can you elaborate on what it takes to make this happen? Is that powered equipment at the OEO conversion or passive? Interesting...
