Abstract
The application discloses a method and apparatus for starting an optical module. The method includes: adjusting temperature of a laser device of the optical module to a first temperature higher than a normal operating temperature of the laser device of the optical module; powering up the laser device of the optical module using a first current lower than a normal operating current of the laser device; and adjusting the temperature of the laser device of the optical module from the first temperature to the normal operating temperature according to a second temperature corresponding to each adjustment, and adjusting the current of the laser device of the optical module from the first current to the normal operating current according to a second current corresponding to each adjustment, for a preset times of adjustment.
