Fiber optic adapter Extralink LC/APC Singlemode Duplex, green, LC/APC connectors

Extralink LC/APC Singlemode Duplex fiber optic adapter is designed to connect two LC/APC single-mode connectors reliably. The duplex configuration supports two-fiber, bidirectional links and is suitable for use in single-mode patch panels, fiber optic enclosures and telecommunication or data center cabling. The green housing identifies the APC polish type and the connector contacts are uncoated to maintain fiber core alignment and optical performance. CE certification ensures compliance with relevant safety and conformity standards.

Advantages

The adapter provides stable mechanical alignment for LC/APC connectors in a compact duplex footprint, reducing insertion loss and back reflection typical for angled physical contact (APC) interfaces. Its green color coding simplifies identification during installation and maintenance. The uncoated connector contacts and precision ferrule fit support consistent optical performance in single-mode networks.

Suitable for

• Single-mode patch panels and fiber distribution frames
• Telecom and data center fiber backbone links
• Fiber optic enclosures and wall-mounted outlets
• Point-to-point duplex single-mode connections

Key specifications

• Connector type: LC/APC duplex interface
• Mode: Single-mode
• Polish type: APC (angled physical contact), indicated by green housing
• Configuration: Duplex (two-fiber) for bidirectional links
• Housing color: Green for APC identification
• Compliance: CE certified

How to use

Insert this LC/APC duplex adapter into the appropriate panel or enclosure cutout, ensuring the keyed orientation matches the adapter slot. Plug LC/APC patchcords into each duplex port until they click into place, making sure connectors are clean and free of dust before mating. For removal, depress the latch on each LC connector and withdraw straight out to avoid damaging the ferrule or sleeve. Maintain APC mating by pairing APC-terminated patchcords exclusively with APC adapters to preserve connector geometry and low back reflection.

Recommendations

Before installation, inspect and clean connector endfaces with approved fiber cleaning tools to minimize insertion loss. Use dust caps when ports are not in use and avoid excessive bending of fiber near the adapter. Match APC-terminated cables with APC adapters only, and verify polishing type by the green housing to prevent incompatible APC/UPC mating.
