Optical module

An optical module, comprising:

• a golden finger, a media access control (MAC) chip, a switch circuit, a laser driver, and a laser;
• wherein,
• a first output terminal of the MAC chip is connected to a first input terminal of the laser driver for inputting burst controlling signal to the laser driver;
• and the burst controlling signal is used to control the laser to be in a burst mode;
• a second output terminal of the MAC chip is connected to a first input terminal of the switch circuit for inputting cut-off controlling signal to the first input terminal of the switch circuit;
• a cut-off controlling pin of the golden finger is connected to a second input terminal of the switch circuit for inputting cut-off controlling signal to the second input terminal of the switch circuit;
• an output terminal of the switch circuit is connected to a second input terminal of the laser driver;
• and the switch circuit is used to connect the first input terminal of the switch circuit with the output terminal of the switch circuit or connect the second input terminal of the switch circuit with the output terminal of the switch circuit;
• and
• the laser driver controls the laser to switch-off according to the cut-off controlling signal.
