Abstract
A novel method for distributed fiber beat length, birefringence and differential group delay (DGD) measurement based on Brillouin optical time domain analysis (BOTDA) technique is proposed. The difference of local maximum and minimum Brillouin gain is determined by scanning input state of polarization (SOP) of pulsed probe wave to recover local beat length. The average beat length, birefringence and DGD measured on 100m SMF28 at 1550nm wavelength with 1m spatial resolution is 11.8m, 1.4×10-7 and 0.21ps respectively.
