Abstract
An optical module includes a gold finger, a comparing unit and a voltage dividing unit. The gold finger includes a plurality of pins. A first pin of the plurality of pins is capable of being multiplexed. The comparing unit includes a first input, a second input and a first output. The first input is connected with the first pin. The second input is configured to receive a reference voltage. The first output is configured to output an output voltage. The voltage dividing unit includes a third input and a second output. The third input is configured to receive a voltage input. The second output is connected with the first pin and configured to regulate a voltage on the first pin, so that the first input of the comparing unit receives a regulated voltage. Voltages of different levels are output by the comparing unit based on a comparison result between an input voltage of the first input of the comparing unit and the reference voltage of the second input.
