Zusammenfassung:The present invention is directed towards a frequency modulated burst mode optical transmitter and systems and methods related thereto. Reverse electrical signals are used to frequency modulate a carrier signal. A carrier detect circuit checks for the presence of a subcarrier signal in received reverse electrical signals. When a subcarrier signal is detected, a laser is turned on and the frequency modulated carrier signal is used to intensity modulate the laser to provide an optical signal. In the absence of a subcarrier signal, the laser is turned off and no optical signals are transmitted. By operating in a burst mode, resources are conserved as optical signals are transmitted only when content-carrying reverse electrical signals are received. A delay circuit may be included to prevent loss of any signal information
