The invention discloses an optical link detection method, device and equipment, a storage medium and a computer program, and belongs to the technical field of optical communication. The method comprises the following steps: receiving a first target signal from a sending end, determining a first channel impact response based on the first target signal, receiving a second target signal from the sending end, determining a second channel impact response based on the second target signal, and determining an equivalent multipath signal-to-noise ratio cost based on the first channel impulse response and the second channel impulse response, wherein the equivalent multipath signal-to-noise ratio cost indicates the multipath effect of the optical fiber. Since the channel impact response indicates the power of the optical signal and the power of the multi-path reflection signal in the target signal, the receiving end can quantitatively determine the interference of the multi-path reflection signal on the optical signal
