摘要:
An addressable optical network interface unit includes an optical input and a radio frequency output. The unit also includes an optical-to-electrical conversion circuit that converts optical signals received at the optical input into radio frequency signals, a directional coupler that is coupled to an output of the optical-to-electrical conversion circuit and a radio frequency receiver that is coupled to a first output of the directional coupler. The radio frequency receiver receives radio frequency signals input through the optical input. The unit also includes a controller that is coupled to the radio frequency receiver, and a filter circuit that is coupled to a second output of the directional coupler. The filter circuit includes multiple signal paths that filter out signals in different frequency ranges. Switches are provided that select one of the signal paths through the filter circuit. These switches are controlled in response to data contained in the radio frequency signal. The controller is configured to generate control signals that control the settings of at least some of the switches based at least in part on a filter control signal received through the optical input.
