An online monitoring method for fiber optic cables based on optical signal reconstruction algorithm and wavelength conversion

The conventional online monitoring method of optical cable mainly uses YOLOv4 (You Only Look Once version 4) vertical detection algorithm to calculate the inclination threshold of optical cable, which is vulnerable to the effect of Brillouin scattering frequency shift, resulting in abnormal monitoring results. Therefore, an online monitoring method of optical cable based on optical signal reconstruction algorithm and wavelength conversion is proposed. In other words, optical signal reconstruction algorithm and wavelength conversion are used to build the optical cable online monitoring model, and the optical cable online monitoring center is designed to complete the optical cable online monitoring. The experimental results show that the optical cable online monitoring method designed based on optical signal reconstruction algorithm and wavelength conversion has good monitoring results, excellent monitoring performance indicators, reliability, and certain application value. It has made certain contributions to improving the safety of optical cable operation and reducing the difficulty of optical cable operation and maintenance.
