Fiber optic adapter Alantec SM LC quad singlemode FOA-LC-SMQ for connecting four LC singlemode ports

Alantec FOA-LC-SMQ is a singlemode fiber optic adapter in a quad LC configuration designed to connect and align four LC singlemode fiber ports. It is intended for use in patch panels, fiber enclosures and rack-mounted installations where compact, high-density connections are required. The adapter facilitates consistent mating of LC connectors, supports low insertion loss and contributes to stable signal transmission in singlemode networks used in telecommunications, data centers and FTTH (fiber-to-the-home) deployments.

Advantages

The quad LC singlemode adapter offers a compact, space-saving solution for high-density fiber terminations. Its precision alignment sleeves ensure accurate connector mating and reduced insertion loss, while durable housing provides mechanical stability in rack and panel environments. The design is compatible with standard LC singlemode connectors, enabling straightforward integration into existing fiber infrastructures and minimizing connection variability across multiple ports.

Suitable for

• High-density patch panels and fiber distribution frames
• Rack-mounted fiber enclosures and splice cabinets
• Data center backbone and interconnect links
• FTTH termination points and residential fiber outlets
• Telecommunications and enterprise singlemode networks

Key specifications

• Fiber type: singlemode (SM)
• Connector interface: LC quad configuration (four LC ports)
• Function: adapter for connection and alignment of LC singlemode connectors
• Installation locations: patch panels, fiber enclosures, rack installations
• Performance characteristics: engineered for low insertion loss and stable optical transmission

How to use

Install the adapter into the designated cutout or panel slot in a patch panel or fiber enclosure according to the chassis or panel manufacturer’s instructions. Insert LC singlemode connectors into the adapter ports until they click into position, ensuring correct orientation and secure seating. For multiport connections, route and manage fiber cables to avoid bending below minimum bend radius and to reduce strain on the connector interfaces. Verify optical continuity and measure insertion loss with appropriate test equipment after installation.

Usage recommendations

To maintain optimal performance, keep connector endfaces clean and inspect them with a microscope before mating. Use dust caps when ports are not in use and follow established fiber handling practices to prevent contamination and mechanical damage.
