Abstract
A system and method are provided for controlling the transmission of RF signals that are to be carried as optical signals over an optical fiber network. Operationally, the optical signals are transmitted as “bursts” in accordance with a standard protocol. For the present invention, transmission control requires an ON/OFF control that incorporates a time delay. Specifically, a “burst” of signals (RF/optical) is initiated when power in the RF input signal passes a predetermined threshold. After an established turn-on time that is set by the time delay, the ON/OFF control activates a laser diode for transmission of the “burst.” Further, the present invention provides control for constant optical output power from the laser diode. Importantly, the laser diode is OFF when a “burst” is not being transmitted.
