1×2 1310/1480/1550nm Polarization Beam Splitter (PBS) is a high-precision optical device that can split input light into P-polarized light and S-polarized light according to the polarization state of the light. It is suitable for three common communication wavelengths of 1310nm, 1480nm and 1550nm. This PBS has low insertion loss, high extinction ratio and stable optical performance.
