A spatial resolution of 10 cm was obtained for distances of 60~80 km in different field environments using phase-noise-compensated optical frequency domain reflectometry. The outstanding spatial resolution makes it possible to identify high-birefringence sections along installed cables. In field trials, we successfully observed beat lengths as small as ~20 cm, which showed that there were very large birefringence sections in the installed cables. To the best of our knowledge, this is the first… CONTINUE READING
