  • Publication number: 20080240732
    Abstract: An optical communication module includes a driving unit, an optical transmitting unit, a control unit and a signal transform control unit. The driving unit outputs a bias signal and a modulation signal in accordance with a bias control signal and a modulation control signal. The optical transmitting unit is electrically connected to the driving unit, outputs an optical signal in accordance with the bias signal and the modulation signal, and generates a feedback signal. The signal transform control unit is electrically connected to the driving unit and generates the bias control signal and the modulation control signal to be inputted to the driving unit. The control unit is electrically connected to the optical transmitting unit and the signal transform control unit, and controls the signal transform control unit in accordance with the feedback signal. A control method of the optical communication module is also disclosed.

  • Publication number: 20070019966
    Abstract: An optical transceiver module for transmitting an optical signal includes a receiver, a clock data recovery circuit and a controller. The receiver receives the optical signal and converts the optical signal into an electric signal. The clock data recovery circuit receives the electric signal and recovers the clock and data of the electric signal. The controller is electrically connected with and monitors the clock data recovery circuit. Also, a control method of an optical transceiver module is provided.
