The EXFO FOA-222 is an FC fiber optic adapter engineered to minimize back reflection at the detector interface, delivering improved measurement repeatability in demanding optical measurement applications. This low-reflection adapter ensures reliable ferrule positioning and optimal signal transmission when connected to EXFO benchtop and modular detectors, making it essential for systems where reflection-induced signal loss directly impacts measurement accuracy.
## Technical Specifications
**Connector Type:** FC (Female to Female)
**Series:** FOA-2XX
**Reflection Mitigation Method:** Coating surface design on adapter body
**Ferrule Positioning:** Engineered to strict tolerances for repeatable detector interface alignment
## Key Features
• Minimizes back reflection through specialized coating surface design
• Ensures repeatable ferrule positioning for consistent measurements
• Optimizes signal transmission by reducing reflection-induced losses
• Manufactured to tight mechanical tolerances for reliable detector coupling
• Distinct architecture differentiating it from the FOA-3XX series aperture-based approach
## Typical Applications
The FOA-222 addresses measurement repeatability challenges in optical test environments where back reflection degrades signal fidelity. Applications include precision power measurement and detector-based optical characterization where signal integrity directly correlates to measurement confidence. The adapter is also compatible with legacy scientific instrumentation such as the IQ-200 power meter family.
## Compatibility & Integration
The FOA-222 interfaces directly with EXFO benchtop and modular detector modules via FC receptacle. Beyond its primary FC connector, the adapter architecture supports connection to multiple patch cord connector types—E-2000, LC, MT-RJ, and MU—enabling flexible integration across diverse optical test configurations and legacy equipment platforms.
