Polarization Beat Length Distribution Measurement in Single-Mode Optical Fibers with Brillouin Optical Correlation-Domain Reflectometry

摘要

The polarization beat length distribution along a single-mode optical fiber (SMF) is measured with a Brillouin optical correlation-domain reflectometry. The beat lengths of SMFs wound on mandrels with radii 10.0, 7.4, and 3.1 cm were measured to be 25.4, 12.1, and 2.56 m, respectively, which agreed well with the theoretical calculations. A distributed measurement was also successfully performed using an SMF comprising two sections with different mandrel radii.
