Exfo FOA-322 FC Fiber Optic Adapter Ultra-Low Reflection

The Exfo FOA-322 is an FC fiber optic adapter engineered to deliver ultra-low reflection performance for precision optical measurements and high-speed data transmission. It minimizes signal loss and back reflection through a 200 µm pinhole aperture that blocks detector lens reflections and a specialized coating surface design. The adapter maintains typical repeatability of 0.001 dB using an LED source, ensuring consistent results across repeated measurements. Manufactured to strict tolerances for repeatable ferrule positioning, the FOA-322 represents an advancement over the FOA-2xx series with improved reflection characteristics.
