The invention provides a compatible circuit for changing rising and falling time of an output electric signal for an optical module, which comprises a photodiode and a Driver driving chip, the output end of the Driver driving chip is electrically connected with a mainboard, and the photodiode is electrically connected with a corresponding input port of the Driver driving chip. The photodiode corresponds to a first output port and a second output port of the Driver driving chip, the first output port is electrically connected with a main board through a first capacitor, the second output port is electrically connected with the main board through a second capacitor, and when the rising and falling time of an output electric signal needs to be shortened, the output end of the first capacitor is connected with the output end of the second capacitor through a third capacitor. The compatible circuit for changing the rising time and the falling time of the output electric signal is used for the optical module, the 1
