Gracyfiber’s PM Patch Cords are high-quality fiber jumpers built with polarization-maintaining (PM) fiber to ensure stable linear polarization from end to end. Available in 1-core or 2-core configurations, they cover wavelengths from 405nm to 1625nm — perfect for quantum optics, laser systems, telecom, sensing, and test setups.
With low loss, high extinction ratio, and flexible connector options, these patch cords deliver reliable performance in both lab and industrial environments where polarization fidelity matters.
