Patent ID: 7684707

Claim:
A method, comprising: selecting downstream optical signals by: receiving a selection signal corresponding to a level of service of a subscriber at a central office, and generating a modulated electrical output in accordance with the selection signal at the central office; converting the modulated electrical output into the selected downstream optical signals at the central office by modulating an optical output of a first laser; receiving, at a subscriber premises, the selected downstream optical signals out of a plurality of downstream optical signals from an information distribution system, the selected downstream optical signals corresponding to the level of service of the subscriber to the information distribution system; converting the selected downstream optical signals to electrical signals; passing each of the electrical signals through a downstream cascaded demultiplexer-filter pair; transmitting the electrical signals as radio frequency signals to one or more connected devices at the subscriber premises; receiving an upstream electrical signal from one of the one or more connected device at the subscriber premises; converting the upstream electrical signal into an upstream optical signal by modulating an optical output of a second laser; and transmitting the upstream optical signal to the information distribution system.
