MMA fiber optic connectors are modular, high-performance connectors designed to integrate fiber optic, power, and signal contacts with robust sealing and EMI protection.

Overview

MMA connectors are a modular connector series that combines features from multiple connector types, including ARINC 600, with the ability to house fiber optic, power, RF, and Quadrax contacts . They are designed for applications requiring high reliability, low mating forces, and field customization, making them suitable for aerospace, military, and industrial environments .

Fiber Optic Integration

The fiber optic contacts in MMA connectors allow for high-speed optical data transmission while maintaining mechanical robustness. Unlike permanent splices, these connectors enable easy connection and disconnection, which is ideal for maintenance and network reconfiguration . The modular inserts can separate fiber optic contacts from power or signal contacts, reducing interference and simplifying installation .

Key Features

• Modular, removable inserts: Facilitate separation of fiber, power, and signal contacts for customization in the field .
• Sealing capabilities: Comparable to M83527 standards, including shell seal, face seal, and grommet, providing protection against dust, moisture, and fluids .
• EMI shielding: Optional 360° EMI spring ensures effective electromagnetic interference protection, critical in sensitive electronic environments .
• Low mating forces: Designed for ease of connection and disconnection without compromising reliability .
• Customizable designs: Customer-specific configurations allow for tailored solutions to meet unique operational requirements .

Applications

MMA fiber optic connectors are widely used in aerospace, defense, and industrial systems where robustness, modularity, and high-speed optical communication are essential. They are suitable for rack panels, avionics systems, and field-deployable equipment .

Summary

MMA fiber optic connectors provide a versatile, durable, and modular solution for integrating optical fibers with other electrical contacts. Their combination of sealing, EMI protection, and modularity makes them ideal for demanding environments where both optical performance and mechanical reliability are critical .
