PM In-Line Fiber Optic Attenuator (IFOA, Polarization Maintaining)
High-precision In-Line Polarization-Maintaining Fixed Optical Attenuator (PM IFOA) providing calibrated attenuation (1 dB to 30 dB) while preserving input polarization with high extinction ratio (>20 dB) across 780nm to 1550nm wavelengths.
Technical Specifications
Hermetic stainless steel tube design ensures long-term environmental stability. With connectors, IL increases by 0.3 dB, RL decreases by 5 dB and ER decreases by 2 dB.
Configuration and ordering notes
Configuration parameters include operating wavelength, exact fixed attenuation value, and connector polish (FC/APC slow-axis keyed standard).
Key Applications
Coherent receiver dynamic range testing; Optical power leveling in PM fiber networks; Calibration of PM optical sensor systems.
Package Drawing
Package dimensions depend on the configuration. The catalog, ordering information or drawing show different package references; engineering must confirm the final mechanical outline before ordering.
