Product Description
Product Description
The Ultra mini PM Device is a compact, high-performance optical component designed for maintaining polarization integrity in fiber optic systems. Engineered with advanced materials like PANDA fiber and integrated with precision polarization-maintaining (PM) connectors, this device ensures minimal polarization crosstalk and low insertion loss across a wide range of wavelengths (1260–1625 nm). Its ultra-compact design (≤15mm in length) makes it ideal for space-constrained applications such as fiber lasers, sensor networks, and high-speed coherent communication systems. The device incorporates a robust housing with anti-vibration properties, ensuring stable performance in harsh environments.
Features
Polarization Stability: Achieves polarization extinction ratio (PER) ≥30 dB, ensuring consistent polarization state transmission.
Low Loss Performance: Insertion loss ≤0.5 dB and return loss ≥55 dB for efficient signal propagation.
Wide Operating Range: Supports wavelengths from 1260 nm to 1625 nm, compatible with standard telecom and datacom systems.
Durable Construction: Built with corrosion-resistant materials and a hermetically sealed package for long-term reliability.
Easy Integration: Standard FC/APC or SC/APC connectors enable seamless integration with existing infrastructure.
Applications
Fiber Optic Sensors: Used in distributed temperature sensing (DTS) and strain monitoring systems.
Coherent Communication: Enhances signal quality in 100G+ optical transceivers.
Laser Systems: Ensures polarization stability in erbium-doped fiber amplifiers (EDFAs) and fiber lasers.
Aerospace & Defense: Reliable performance in airborne and satellite communication links.
Medical Devices: Enables precise optical alignment in endoscopic imaging systems.
