Potential of the optical reflectometry in the visible spectral range

The paper deals with the development of optical reflectometry technique by the use of visible range probing signal. In this case, the increasing of value of the fiber backscattering plays a positive role. The device registers stronger signals and it leads to reducing of the requirements for device components. The proposed improvement is useful when created devices aimed at measuring of short optical line sections. At the same time, it takes into account the desire to reduce power consumption, performance and cost of the components. The authors propose a structural diagram of the device. The requirements for its functional units are formulated. There is a mathematical model of formation of the backscatter signal with of visible probing signals. At the end of the paper, a variant of fiber trace is given and recommendations for further research are formulated.
