The Exfo FOA-354 is an SC fiber optic adapter engineered to eliminate back-reflection in precision measurement systems. Its 200 µm pinhole aperture blocks detector lens reflection while maintaining strict manufacturing tolerances for repeatable ferrule positioning. This ultra-low-reflection design delivers the high measurement accuracy and repeatability demanded in sensitive optical applications and critical communication links.
## Technical Specifications
• Connector Type: SC (compatible with PC, SPC, UPC, APC polish types)
• Aperture: 200 µm pinhole design
• Series: FOA-3xx (improvement over FOA-2xx series with reduced coating reflection)
• Manufacturing: Strict tolerances for consistent ferrule positioning
## Key Features
• Ultra-low-reflection pinhole aperture for minimal signal loss
• Optimized for high-precision alignment in detector applications
• Durable construction rated for demanding measurement environments
• Supplied in carrying case for protection and portability
## Compatibility & Integration
The FOA-354 integrates directly with all EXFO benchtop and modular detectors. The 200 µm aperture is specifically designed to function with EXFO detector optics. While the broader FOA series supports multiple connector types (E-2000, LC, MT-RJ, MU, SMA, FC, ST), the FOA-354 is dedicated to SC connector applications. The FOA-3xx series represents a generational upgrade for users of older scientific equipment, delivering improved measurement repeatability by minimizing detector lens reflection compared to legacy FOA-2xx adapters.
## Typical Applications
• Sensitive optical measurement systems requiring ultra-low reflection
• Critical communication link characterization
• Precision detector coupling in laboratory and field environments
