The system is based on the optical frequency-domain reflectometry and Rayleigh scattering and enables measurements of optical fibers in both time and frequency domains in the range of the third telecomunnication window (1525 – 1610 nm). The device is characterized by a high dynamic range (80 dB), no dead zone and a high spatial resolution: 10 µm with the measurement range of up to 30 m, and 20 µm with the range of up to 70 m. The device enables measurements of return loss, insertion loss, distributed loss, length, polarization state, phase derivative and group delay. The device is equipped with the distributed sensing mode and the extended measurement range mode (up to 2 km).
