Gracyfiber’s PM Isolator is a 1×1 device that lets light pass in one direction — while blocking back-reflections. Built with precision-aligned PM fiber, it keeps polarization stable and protects lasers from harmful feedback across key wavelengths: 1064nm, 1310nm, 1480nm, 1550nm, and 1650nm.
Available in single or dual stage designs, this compact isolator offers low loss, high isolation, and strong power handling — perfect for laser systems, telecom, sensing, and quantum setups where stability matters.

Remark:
- Above specifications are for devices without the connectors.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.
- The PM fiber and the connector key are aligned to the slow axis, fast axis is blocked.
