The invention discloses a polarization maintaining optical fiber axial strain-birefringence coefficient measurement system and measurement and calculation method. The system comprises a distributed polarization crosstalk analysis system, an output polarization maintaining optical fiber, a polarization maintaining optical fiber to be measured, an input polarization maintaining optical fiber, a first optical fiber strain adjusting frame, a second optical fiber strain adjusting frame, a first reading microscope with a pointer and a second reading microscope with a pointer. The output port of the distributed polarization crosstalk analysis system is connected with the first end of the output polarization maintaining optical fiber. The second end of the input polarization maintaining optical fiber is connected with the input port of the distributed polarization crosstalk analysis system. The second end of the output polarization maintaining optical fiber is connected with the first end of the polarization maintain
