A vendor said that different PON > systems could co-exist, and I took that at face value. True. Different PON systems can co-exist: https://en.wikipedia.org/wiki/NG-PON2 They do however have to be using different PON standards, and thus different wavelengths each. > Do you always need a filter at the ONT for that to work? No. You only need filters if you try to run multiple same generation PONs. This is assuming you could get custom optics for them and run them on different, close by wavelengths. If the wavelengths are off by too much, they will be filtered out automatically. This is why you can run RF video overlay at 1550 nm and do OTDR shots at 1625 nm on a live network without causing interference to the PON.
