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.

Abstract: Methods and apparatus are described for “Smart” RF over Glass (RFoG) CPE Unit with Seamless PON Upgrade Capability. A method includes operating a customer premises equipment device including transporting upstream cable return services with a laser; and switching a drive source for the upstream laser from an analog driver to a digital driver by using a managed electrical switch to reuse a wavelength of the laser. An apparatus includes a customer premises equipment device including a laser for transporting upstream cable return services; and a managed electrical switch coupled to the laser that is used to switch a drive source for the upstream laser to reuse a wavelength of the laser.

Abstract: Methods and apparatus are described for DWDM transport of CATV and digital signals over optical fiber in low-dispersion spectral regions. A method includes transporting a plurality of optical carriers of different wavelengths over an optical link using wavelength division multiplexing, the optical link including a plurality of optical segments. The plurality of optical channel center wavelengths defined by the plurality of optical carriers are clustered proximate an average value of a zero-dispersion wavelength of the optical link, or near either a) a low wavelength edge or b) a high wavelength edge of a range of zero-dispersion wavelengths of the optical link and a plurality of optical channel center frequencies defined by the plurality of optical channel center wavelengths are non-uniformly spaced apart.
