In fiber-to-the-home (FTTH) RF over Glass (RFoG) Architecture a customer-premise-equipment (CPE) includes a wavelength separator. A method includes up-converting a baseband upstream data signal to a frequency band above a frequency band of a baseband downstream data signal; combining the up-converted upstream data signal with an upstream cable return signal; transmitting the up-converted upstream data signal and the upstream cable return signal using a single upstream laser; and separating, with a wavelength separator, A) a downstream data signal and a downstream cable feed signal from B) the combined up-converted upstream data signal and upstream cable return signal.
