Key Features & Technical Highlights:

• Polarization Extinction Ratio (PER) Maintenance: Our switch is designed to minimize polarization crosstalk, guaranteeing a high PER at the output, which is crucial for the performance of your PM system.
• Low Insertion Loss & High Reliability: Featuring precision-aligned PM fiber pigtails and a robust [mechanical or MEMS] switching mechanism, the device ensures minimal signal attenuation and long-term operational stability.
• Fast Switching Speed & Compact Design: With a switching time of typically <10 ms, it supports dynamic network reconfiguration. Its compact form factor allows for easy integration into dense optical assemblies.
• Tailored Configurations: Available in various standard configurations 1×2, 2×2 to meet diverse system architecture needs. Explore our full range of PM components in the product section at https://www.feiyi-oeo.com/product-category/polarization-maintaining/.

Primary Applications:
This switch is indispensable in applications requiring dynamic control over polarized light paths:

1. Fiber Laser Systems: For reliable protection switching, pulse picking, or beam routing without compromising polarization.
2. Quantum Information Processing: Where maintaining qubit integrity (encoded in polarization) during path switching is fundamental.
3. Advanced Sensing & Instrumentation: Enables multi-channel sensing or system calibration in interferometric and coherent detection systems.
