Abstract:
Methods and apparatus are described for fiber-to-the-home (FTTH) RF over Glass (RFoG) Architecture and customer-premise-equipment (CPE). 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; transmitting the up-converted upstream data signal and the upstream cable return using a single upstream laser; separating the frequency up-converted data signal from the upstream cable return using an RF diplexer; and down-converting the frequency up-converted upstream data signal back to baseband. An apparatus comprises: a frequency up-converter that up-converts a baseband upstream data signal to a frequency band above a frequency band of a baseband downstream data signal; a frequency combiner coupled to the frequency up-converter that combines the up-converted upstream data signal with an upstream cable return; a single upstream laser coupled to the frequency combiner that transmits the up-converted upstream data signal and the upstream cable return; an RF diplexer coupled to the single upstream laser that separats the frequency up-converted data signal from the upstream cable return; and a frequency down-converter that down-converts the frequency up-converted upstream data signal back to baseband.
