If you look at Jay may be referring to something I alluded to earlier, what Calix refers to as RF overlay. The RF signal from the traditional cable system is converted to 1550nm and combined onto the PON before the splitter with a CWDM module. Certain model ONT's split the 1550 back off and convert back to an RF port.
