摘要: The present invention is directed towards a frequency modulated burst mode optical system. More specifically, signals having common wavelength provided by plurality of transmitters are passively combined onto single fiber. A receiver then receives the and processes them accordingly. Each includes modulation modulator that modulates reverse electrical at frequency, such as 1.21 GHz. Additionally, carrier detect circuit monitors for presence signal. Subsequently, only in signal, an laser turned on, thereby converting into signals. Advantageously, transmitted if signal detected. Due to burst-mode transmission signals, can be receiver.
