This disclosure provides an optical module and a method for improving optical module communication. The MCU monitors the level of the module selection pin. Upon detecting a level change in the module selection pin, it sets an interrupt flag to a first value. If the interrupt flag is read as the first value, an interrupt function is initiated. The interrupt function sets the interrupt flag to a second value. The interrupt function then determines whether the monitored level is low. If it is high, the interrupt function closes the first I2C interface; if it is low, the interrupt function opens the first I2C interface, allowing the host computer and the optical module to communicate normally via I2C. By setting the interrupt flag to the second value before determining whether the monitored level is low, the interrupt function avoids clearing the interrupt flag set when the module selection pin changes from high to low, allowing the interrupt function to open the first I2C interface and thus enabling normal I2C communication between the host computer and the optical module.
