主　　题：OTDR polarization fiber 

摘      要：A new polarimetric optical time domain reflectometry(P-OTDR)measurement device assisted by a high speed polarization analyzer is designed and a new algorithm,which can be used to accurately measure the birefringence vector,is *** this method,only one measurement is required and the result is insensitive to the input state of *** 1-km single mode fiber(SMF)is measured and the distribution of the local birefringence vector along the SMF is obtained with a resolution of 2 cm.
