Applications
Learn More
A polarization-maintaining optical connector (PSI) achieves precise coupling alignment of polarization modes through precise connector keying.
Compared to traditional fiber optic patch cords, PSI offers advantages such as maintaining the direction of linear polarization during polarization-maintaining signal transmission, improving the coherence signal-to-noise ratio, and enabling high-precision measurement of physical quantities.
The PSI connector is a crucial component for coupling two polarization-maintaining optical fibers. It ensures that the polarization modes of the two fibers maintain the original polarization state of the polarized light during coupling, maintaining a high extinction ratio for transmission. This requires precise alignment of the slow or fast axes of the two fibers to minimize θ-angle errors. Aligning the polarization direction of the polarized light with one axis minimizes the polarization component on the other axis, thus preserving the polarization state of the transmitted light.
The polarization-maintaining angle and extinction ratio reflect the quality of polarization state preservation.
