Gracyfiber’s PM PBS / PBC is a 1×2 fiber device that splits or combines light by its polarization state — while keeping that state stable across all ports. Built with precision-aligned PM fiber, it works reliably from 980 nm to 1620 nm.
Designed for laser systems, telecom, sensing, and quantum applications, this compact component offers low loss and high polarization purity. Available in multiple grades and package types, it is ready for both lab use and industrial deployment.

Remarks:
- 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.
