The FC Detector Interface Adapter from VIAVI Solutions / JDSU is a precision connector interface engineered for fiber optic test measurements. Designed for 2.5mm ferrules, this adapter directly couples test cables to photodetectors in optical measurement systems. It supports both FC-PC and FC-APC connectors with a universal push-pull design, accommodating fiber optic components across single-mode and multimode installations.
Technical Specifications
• Product Family: RX Series, RX3, RX-3
• Connector Type: FC (FC-PC and FC-APC compatible)
• Ferrule Size: 2.5mm
• Weight: 5 lbs per unit
• Construction: Stainless-steel precision components
– Key Features
• No deadzone operation for accurate near-connector measurements
• Multidisplay mode capability
• Built-in reflection trap eliminates multiple reflections between connector end face and detector, maintaining measurement accuracy independent of connector reflectivity and surface quality
• Wide backreflection range measurement
• Universal push-pull design for PC and APC connector compatibility
• Three locking pins (AC900 series) for enhanced measurement precision
• AC901 variant features locking mechanism for improved stability
– Typical Applications
This adapter interfaces directly with VIAVI optical test instruments for loss and backreflection characterization. Applications include single-component testing through automated multifiber test scenarios. The adapter supports both SM and MM fiber systems in development, deployment, and maintenance workflows.
– Compatibility & Integration
The adapter is compatible with the complete VIAVI MAP series optical power meters (mOPM), Insertion Loss/Return Loss Meters (mORL and mOLM), and Swept Wavelength Systems (mSWS). It integrates with OCC-55 CWDM and OCC-56C DWDM Smart Optical Channel Checkers, as well as OLS34, OLS-35, and OLS-36 Optical Light Sources. Full backward compatibility exists with legacy JDSU C-Series instruments and product lines. The AC900 series detector adapters function with all current MAP series detectors.
