Alantec Adapter fiber optic singlemode LC/APC duplex, no-flange (FOA-LCA-SMDS)

The Alantec Adapter fiber optic singlemode LC/APC duplex, no-flange is designed for precise inline coupling of two LC/APC duplex connectors in singlemode networks. Its flange-less form factor allows compact installation in patch cords, fiber extension assemblies or custom panel solutions where space is limited. The adapter provides accurate ferrule alignment for low optical loss and stable mating performance, making it suitable for telecom applications and FTTH connections that use angled physical contact (APC) ferrules.

Advantages

The flange-less construction minimizes connector footprint and supports compact inline or panel-mounted configurations without additional housing. High-precision alignment reduces insertion loss and back-reflection for LC/APC ferrules, preserving signal integrity in singlemode links. The duplex LC configuration supports bidirectional or paired fiber channels while ensuring consistent mechanical engagement and repeatability across mating cycles.

Suitable for

• Telecom singlemode fiber links requiring LC/APC angled connectors
• FTTH installations and residential fiber termination
• Inline patching or extension of duplex LC/APC patch cords
• Custom panel or enclosure assemblies where compact adapters are needed

Key specifications

• Connector type: LC/APC duplex interface for singlemode fibers
• Form factor: flange-less (no-flange) inline adapter
• Polish type: angled physical contact (APC) for reduced back-reflection
• Application: singlemode optical networks, patching and extensions
• Mechanical: duplex alignment sleeve to ensure ferrule mating accuracy

How to use

Insert the LC/APC duplex connectors into each end of the adapter until they click or seat fully, ensuring the angled ferrule faces are mated correctly to maintain APC contact geometry. Use the adapter inline between two patch cords or within a custom panel cutout designed for flange-less adapters. Verify low insertion loss with appropriate test equipment after installation and avoid rotating mated connectors to preserve APC alignment.

Usage recommendations

Handle the adapter and connectors with clean hands and dust-free procedures. Clean ferrule end faces before mating with approved fiber cleaning tools, and store unused adapters with protective caps to prevent contamination. For permanent panel installations, ensure proper mechanical support to avoid strain on the fiber connections.
