## Summary description

Alantec FOA-LC-MMDS-4 is a flangeless LC duplex fiber optic adapter for OM4 multimode cables. Designed for connecting and aligning LC multimode connectors in patch panels or enclosures, it supports duplex LC connections and maintains fiber alignment without a mounting flange. Suitable for data center and LAN multimode link installations where OM4 performance is required.

## Long description

Alantec OM4 multimode LC duplex flangeless adapter FOA-LC-MMDS-4 is designed to provide precise alignment and secure connection for LC multimode fiber optic connectors in environments where OM4 performance is required. This flangeless LC duplex adapter accepts two LC connector ferrules and establishes duplex links without a mounting flange, making it suitable for high-density patch panels and modular enclosures. The adapter supports multimode transmission characteristics of OM4 fiber systems and is intended for use in data center, campus, and enterprise LAN installations where reliable multimode interconnects are needed.
Advantages
The flangeless design reduces space requirements and allows flexible placement in panels and modules that do not accommodate a flange. Precision internal alignment sleeves maintain low insertion loss and repeatable mating performance for LC multimode connectors. Constructed for compatibility with OM4 multimode fiber, the adapter helps preserve modal bandwidth and signal integrity across short- to medium-range multimode links. Its duplex configuration enables simultaneous transmit and receive channels within a single adapter footprint.
Suitable for
High-density patch panels and modular rack enclosures
Data center multimode trunk and patch cabling
Enterprise LAN links using OM4 multimode fiber
Telecom rooms and equipment racks with LC duplex connectors
Key specifications
Type: LC duplex flangeless adapter
Fiber mode: Multimode (OM4)
Connector compatibility: LC multimode connectors (duplex)
Alignment: Precision internal alignment sleeves
Mounting: Flangeless for panel/module insertion
Application: Short- to medium-range multimode links in data centers and LANs
How to use
Insert the adapter into the designated module slot or panel cutout that accepts flangeless LC adapters. Ensure the adapter is firmly seated and aligned with the panel openings. Insert LC multimode connectors into each duplex port until the latches engage, verifying secure mechanical engagement. For disconnection, depress the LC connector latch and withdraw the connector straight out to avoid disturbing adjacent connections. Follow standard fiber handling practices to keep connector endfaces clean and to minimize insertion loss.
Usage recommendations
Before mating connectors, inspect and, if necessary, clean connector endfaces with appropriate fiber cleaning tools to maintain OM4 performance. Use dust caps on unused ports and avoid excessive bending of multimode cables near the adapter to preserve link quality. When installing in high-density environments, plan port labeling and cable routing to prevent strain on duplex LC connections.
