GPON is 1490 down and 1550 up

I've been using CWDM which overlaps that.  I hadn't looked at DWDM.

DWDM C band is 1525-1565 which would overlap.

DWDM L band is 1570-1625.....so yeah I guess a DWDM MUX that only touched L-Band might pass GPON through.  Maybe I've been looking at it through the wrong lens.

Cant you just use a dwdm with expansion port? everything not in the dwdm range 
would get spit out the expansion port (gpon).

Why isn't there a MUX that carries GPON on one port and then also allows me a 
few ethernet paths on other wavelengths?  I feel like this would be a really 
useful thing for people leasing dark fiber, so I can't fathom why it's not a 
commodity item.
