A high-voltage pulse protection device includes an input connector, a separating capacitor and an output connector. A video receiving terminal of the input connector receives a video signal from a RF cable. An input terminal of the separating capacitor is electrically connected to a video transferring terminal of the input connector to receive the video signal. An output terminal of the separating capacitor induces and outputs a sub-signal response to the video signal. A video receiving terminal of the output connector receives the sub-signal, and a video transferring terminal of the output connector transfers the sub-signal to a video processing module.

An optical burst mode receiver comprises a photo-detector receiving an optical signal for conversion to a current signal, a transimpedance amplifier receiving and converting the current signal into first and second transmit signals, a limiting amplifier comprising first and second input terminals and an output terminal generating a data signal, and a control circuit coupled to the first and second transmit signals to verify that if the optical signal is valid. The control circuit is further coupled to the first and second input terminals of the limiting amplifier. When the optical signal is valid, the control circuit provides the first and second input terminals with the first and second transmit signals respectively to generate the data signal. When the optical signal is invalid, the control circuit provides the first and second input terminals with distinct voltage levels to maintain the data signal at a steady level.
