1. A high-speed optical module for an optical fiber channel, wherein, the high-speed optical module comprises:

  • a hot swappable electrical connector, for providing a data and signal transmission electrical interface between the high-speed optical module and a system board;

    an emission waveshaping electrical circuit, for waveshaping an emitted electrical signal that is received, to compensate loss in a transmission medium and reset jitter, wherein a first synchronous signal is extracted from the emitted electrical signal, and jitter and noise are removed to recover a data signal;

    a diode driving electrical circuit, for providing a proper bias current and a proper modulating current, to drive a vertical cavity laser emission diode;

    the vertical cavity laser emission diode, for performing electrical optical conversion to the received electrical signal and outputting an optical signal;

    a detector, for receiving the optical signal and completing photovoltaic conversion;

    a pre-amplification electrical circuit, for preliminarily amplifying the received electrical signal;

    a limiting amplification electrical circuit, for further amplifying the received electrical signal, wherein a second synchronous signal is extracted from the received electrical signal and jitter and noise are removed to recover a second data signal;

    a receiving equalizer electrical circuit, for optimizing connection performance and a dispersive parameter; and

    a controller for configuring a working mode of the high-speed optical module according to a controlling command issued by a network administrator, and monitoring a working state of the high-speed optical module, and reporting related data;

    wherein the hot swappable electrical connector, the emission waveshaping electrical circuit, the diode driving electrical circuit and the vertical cavity laser emission diode are connected in sequence;

    the detector, the pre-amplification electrical circuit, the limiting amplification electrical circuit, the receiving equalizer electrical circuit and the hot swappable electrical connector are connected in sequence; and

    the controller is individually connected to the diode driving electrical circuit, the limiting amplification electrical circuit, and the hot swappable electrical connector.
