A signal transmission circuit of a magnetic resonance imaging system, an optical communication module, and a system are provided. The signal transmission circuit includes: a processing circuit, which receives electrical signals from a plurality of signal receiving coil elements of the magnetic resonance imaging system, and respectively modulates the electrical signals from the plurality of signal receiving coil elements to corresponding non-overlapping frequency bands; and a receiving circuit, which is connected to the processing circuit and extracts the electrical signal in each frequency band from an output signal of the processing circuit. According to the present application, the number of channels of a signal is reduced, the difficulty of signal transmission and processing is reduced, and the number of elements of a signal transmission circuit is reduced. As a result, the difficulty of aspects such as chip design, manufacturing, and thermal management can be reduced.
