Abstract
The disclosure provides an optical module. In the optical module, emitters of a first PNP type triode and a second PNP type triode connected with a power source are high-level always, when a bias pin of a laser transmitter driver chip is high-level, bases of the two PNP type triodes are both high-level and in an OFF state, no current flows to the bias pin and a laser transmitter, and the laser transmitter does not emit light; when the bias pin of the laser transmitter driver chip is low-level, the bases of the two PNP type triodes are both low-level and in an ON state, the current flows to the bias pin and flows from a positive terminal of the laser transmitter, and the laser transmitter emits light.
