Feiyi OEO PM Optical Switches: Millisecond-Smart Control for Precision Optical Paths
In demanding high-end optical systems, flexible switching and control of light paths are often key to enabling complex functionalities and enhancing system reliability. The Polarization-Maintaining (PM) Optical Switches from Shenzhen Feiyi Optoelectronic Communication Co., Ltd. (Feiyi OEO) are core passive components designed precisely for such applications. They enable high-speed, stable optical path switching while preserving the polarization state of the light signal, making them an ideal choice for building advanced systems in fiber sensing, quantum communication, and test instrumentation.
Core Characteristics: Precise, Fast, Reliable
This series of PM Optical Switches is optimized for polarization-sensitive systems, offering the following key features:
- Polarization-Maintaining Design: Utilizes PM fiber (e.g., Panda-type) and precision alignment processes to ensure excellent Polarization Extinction Ratio (PER) during switching, minimizing Polarization-Dependent Loss (PDL). This is crucial for applications like interferometry and coherent detection.
- Ultra-Fast Switching Speed: Employs mature and reliable MEMS or micro-opto-electro-mechanical system technology to achieve channel switching in milliseconds (typically a few ms), meeting the demands of dynamic testing and real-time system control.
- Superior Optical Performance: Features low Insertion Loss, high Channel Isolation, and excellent repeatability and stability, ensuring signal transmission quality and reducing system errors.
- High-Reliability Design: Products undergo rigorous testing, offering long lifetime, low power consumption, and the ability to operate over a wide temperature range, suitable for industrial and research environments.
- Flexible Configurations: Available in various channel configurations (e.g., 1xN, Nx1), connector types (FC/APC, SC/APC, etc.), and supports customized wavelength windows to meet specific system integration needs.
