Due to the traditional method neglecting the control of the radiation energy of the submarine dark signal, and the loss caused by the measuring device is not removed in the process of measuring the heat loss of optical elements, the result of optical fiber communication engineering reinforcement is not ideal. The key technology of submarine optical fiber communication project reinforcement based on low power sensor network is proposed. The ionizing radiation damage effect of CCD is analyzed. The dark signal of CCD is measured and the dark signal of CCD is increased by bias irradiation. On this basis, the uniform sea bottom temperature model is constructed by using low-power temperature sensor network to solve the heat conduction equation of the optical elements on the seabed, so as to realize the reinforcement of the submarine optical fiber communication engineering. The experimental results show that the proposed method achieves the ideal reinforcement effect of submarine optical fiber communication engineering by measuring the heat loss of submarine optical elements with high precision and reducing the damage of components, which provides a reference for the further development of submarine optical fiber communication engineering.
