description The invention discloses an optical module program downloading device. A USB (Universal Serial Bus) cable is connected with a USB interface of a PC (Personal Computer) and a USB interface of the downloading device, and a power conversion chip is connected with the USB interface of the downloading device and a multi-channel power switch. The MCU is connected with the power switch and the multi-channel optical module slot. After the optical module is inserted into the slot, the MCU detects the type of the inserted module and then turns on the power switch of the corresponding channel to power on the optical module. And after the firmware downloading program in the PC identifies the model of the module, the PC issues an IIC or SWD bus instruction to the microcontroller MCU, and downloading of the optical module program is executed. The method has the advantages that downloading and updating of firmware programs can be carried out on optical modules in different packaging forms under the condition that no external
