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.
