Fiber optic adapter Alantec multimode OM4 LC quad (FOA-LC-MMQ-4)

The Alantec fiber optic adapter for multimode OM4 cabling with LC quad configuration is designed to connect and align LC quad multimode fiber connectors. It provides a compact interface for mating two LC quad connectors, enabling reliable optical continuity between fiber patch panels, transceivers and active equipment in high-density installations. The adapter is compatible with OM4 multimode fiber performance requirements and is intended for use where optimized modal bandwidth and low insertion loss are required.

Advantages

The adapter offers precise alignment of quad LC ferrules to minimize insertion loss and back reflection. Its compact quad format saves panel space while supporting high port density. Manufactured to maintain consistent OM4 multimode optical characteristics, the adapter contributes to predictable network performance and simple field installation. The mechanical design supports stable physical connection and repeated mating cycles without degradation of optical contact.

Suitable for

• High-density data center fiber patch panels and cassettes
• Telecom and server rack installations requiring OM4 multimode cabling
• Interconnecting multimode transceivers, switches and storage equipment
• Fiber backbone segments and short-reach high-speed links within buildings

Key specifications

• Connector format: LC quad (4-fiber) multimode mating interface
• Fiber type: multimode OM4-compatible performance
• Typical insertion loss: low insertion loss design for multimode links
• Return loss: optimized for multimode applications
• Housing: compact high-density form factor suitable for patch panels
• Mating cycles: designed for multiple repeatable connections

How to use

Install the adapter into a compatible fiber patch panel or cassette port by aligning the housing with the panel opening and securing it according to the panel's mounting method. Insert LC quad multimode connector plugs straight into the adapter until they seat fully; ensure connectors and fiber ends are clean before mating to avoid elevated loss or contamination. For removal, gently withdraw the connector while supporting the cable to avoid strain on the fiber. Use appropriate dust caps when the adapter is not in use.

Usage recommendations

Regularly inspect and clean connector end faces with approved fiber cleaning tools before connecting. Use OM4 multimode patch cords and transceivers matched to the same fiber specifications to maintain intended bandwidth and link performance. Avoid sharp bends and mechanical stress on fiber cables near the adapter and follow standard fiber handling and safety procedures when installing and servicing connections.
