Fiber Optic Adapter Alantec OM4 LC Duplex (FOA-LC-MMD-4) – Multimode LC/LC

Alantec OM4 LC Duplex fiber optic adapter provides a precision-fit coupling for two LC-terminated multimode fibers. Intended for OM4 multimode networks, this LC/LC duplex adapter ensures accurate ferrule alignment and low insertion loss when connecting patch cables in patch panels, chassis or equipment panels. It is suitable for installations where reliable LC duplex connections are required for high-speed local area networks and data center links.

Advantages

The adapter is designed for OM4 multimode fiber, delivering consistent optical alignment and minimal signal loss at multimode wavelengths. Its compact LC duplex form factor saves panel space and allows easy insertion of LC patch cords. Manufactured to industry tolerances, the adapter facilitates stable connections, helps maintain channel performance and simplifies fiber management in dense cabling environments.

Suitable for

• Connecting two OM4 multimode LC patch cables in patch panels
• Field installation in network chassis and fiber enclosures
• Data center horizontal and equipment-side multimode links
• Upgrading or extending multimode LC/LC fiber runs

Key specifications

• Fiber type compatibility: OM4 multimode
• Connector type: LC duplex (LC/LC)
• Polish type: compatible with standard multimode ferrule polishes
• Insertion loss: low (designed for minimal attenuation in multimode links)
• Form factor: duplex housing suitable for high-density panels
• Mounting: snap-in or panel-mount compatible with standard adapter cutouts

How to use

Install the adapter into the panel or chassis cutout following the equipment manufacturer’s instructions, ensuring the adapter snaps or secures into place. Align and insert LC-terminated multimode patch cords into each side of the duplex adapter until a positive stop is felt. Check connections for secure seating and test the link for acceptable optical loss using appropriate measuring equipment. When disconnecting, depress the LC connector latch and pull straight out to avoid damaging ferrules.

Usage recommendations

Use factory-terminated LC multimode patch cords rated for OM4 to preserve link performance; avoid contaminating ferrule endfaces by keeping dust caps on until final connection and cleaning endfaces when necessary with appropriate fiber cleaning tools.
