Airborne Fiber Optic Cable Connector

Airborne fiber optic cable connectors are rugged, high-speed interconnects designed for aerospace, defense, and space applications, offering EMI protection, long-distance data transmission, and environmental resilience.Overview

Airborne fiber optic connectors are engineered to maintain high data integrity and reliability in harsh environments, including extreme temperatures, vibration, radiation, and outgassing conditions typical of aerospace and defense systems. These connectors are often integrated into active optical cable assemblies that convert electrical signals to optical signals for high-speed transmission over long distances, while minimizing weight and size compared to traditional copper cables (Molex AirBorn FOCuS) .

Key Features

• High Data Rates: AirBorn FOCuS Active Optical Cables support up to 14 Gbps per lane, with four lanes providing up to 50 Gbps aggregate bandwidth .
• Ruggedization: Connectors and cables are vibration-resistant, radiation-hardened, and environmentally sealed, suitable for space-rated and airborne applications .
• EMI Protection: Optical transmission inherently resists electromagnetic interference, and shielded connector housings further enhance compatibility in high-EMI environments .
• Interchangeability: Many systems, such as AirBorn FOCuS, allow copper and fiber cables to share the same pinout, simplifying design and maintenance .
• Factory Termination: Cables are pre-terminated and sealed, reducing the risk of contamination and eliminating the need for field fiber termination or cleaning .

Connector Types and Standards

• Military and Aerospace Standards: Common connectors include MIL-DTL-38999, MIL-DTL-83526 (GFOCA), MIL-PRF-28876, and ARINC 801, providing high-density, low-loss, and reliable termini for airborne systems .
• Genderless and Rear-Release Termini: Many airborne connectors, such as NGCON and Glenair SuperNine® series, feature genderless or rear-release termini for easier installation and maintenance in confined spaces .
• Board-Level and Panel-Mount Options: Connectors are available in board-mount, right-angle, and panel-mount configurations, allowing flexible integration into avionics and spacecraft systems .

Applications

Airborne fiber optic connectors are used in:

• Military aircraft and UAVs for high-speed sensor and communication links.
• Spacecraft and satellites, where radiation resistance and outgassing compliance are critical.
• C4ISR systems requiring high-bandwidth, low-latency data transmission.
• Industrial and commercial aviation, benefiting from reduced weight and EMI immunity .

Advantages Over Traditional Copper or Fiber

• Weight and Size Reduction: Active optical cables are lighter and smaller than equivalent copper assemblies.
• Ease of Installation: Factory-terminated and sealed connectors reduce field maintenance.
• High Reliability: Optical transmission avoids EMI issues and maintains signal integrity over longer distances.
• Design Flexibility: Interchangeable copper/fiber pinouts allow system designers to adapt to different cable lengths and performance requirements without redesigning connectors . Airborne fiber optic cable connectors are essential for mission-critical airborne and space systems, providing a combination of high-speed data transfer, environmental resilience, and simplified installation that traditional copper or standard fiber solutions cannot match.
