High Speed and Fiber Optic Connector Solutions
The demand for high-speed interconnect solutions that can enable massive data transmission has never been greater.
The next generation of military and defense platforms are here, and they require substantial amounts of data to enable autonomous systems, advanced data processing, artificial intelligence, and other next-generation mission-critical capabilities. As these new systems are more widely utilized, data transmission speeds must keep pace with rapidly evolving operational requirements. Legacy systems also require the best in high-speed interconnect performance as these systems are retrofitted with modern capabilities.
High Speed and Fiber Optic Interconnect Systems for Any Rugged Application
How To Select the Best High Speed Connector for Your Application?
The first consideration is ensuring the connector supports the required data transmission rate and protocol. High-speed connectors are designed for Gigabit Ethernet, 10G/40G/100G Ethernet, Fibre Channel, PCIe, USB 3.0, and other high-bandwidth protocols. Matching the connector’s electrical performance − such as impedance control and signal integrity − to your system’s requirements is critical for reliable operation and compatibility in your assembly.
You should also consider what data speeds and transmission capabilities you will need so you can choose the right contacts for your application. The operating environment of your connector is also extremely important, as you will need to select an interconnect with the right protection and ruggedization.
Amphenol Military High Speed offers wide selection of high-speed interconnect solutions, including:

What Is a Military High Speed Connector?
A military high-speed connector is a connector – typically a circular, rectangular, or board-to-board connector – that’s designed to enable high-bandwidth data transmission while maintaining ruggedness, reliability, and signal integrity in harsh environments. Military high-speed connectors are ideal for high-bandwidth applications such as radar, ISR, avionics, and real-time communications throughout the military and aerospace markets.
These connectors support data rates from 1 Gbps to 100 Gbps or more across a variety of protocols including Ethernet, PCIe, Fibre Channel, SOSA-aligned and VPX systems. Because they’re designed to support harsh-environment applications, they’re able to deliver mission-critical signal and data while withstanding extreme shock, vibration, humidity, and temperature conditions while ensuring low insertion loss and minimal signal degradation.
Advanced EMI/RFI shielding enables these connectors to maintain signal integrity in electronic warfare and high-noise environments. There are a variety of high-speed contact and termination systems available for these connectors − including high-performance copper and fiber optic termini – that minimize signal loss and support differential pair architectures.
How Reliable are High Speed Connectors in Harsh Environments?
Amphenol High-speed connectors are designed for harsh environments and must endure harsh environmental conditions including shock, vibration, temperature fluctuations, and more. Our connectors meet standards such as MIL-DTL-38999 for circular connectors, ARINC 801 for fiber termini, or those aligned with The Open Group Sensor Open Systems Architecture (SOSA™) and OpenVPX for high-speed embedded computing and sensor systems.
Fiber Optic vs. Copper for Military Applications
The choice between copper and fiber optic contacts depends on distance, bandwidth, and environmental factors surrounding your application. Copper-based contacts, such as Quadrax, Twinax, and Triax, provide high-speed performance for shorter distances such as within aircraft and vehicle data networks. Fiber optic connectors, such as ARINC 801 and MIL-PRF-29504 termini, offer expanded EMI immunity and higher bandwidth over longer distances.
While fiber optics offer superior bandwidth and lower signal loss over long distances, copper remains a practical choice for high-speed, short distance applications that prioritize mechanical durability and ease of termination. The best solution depends on the specific performance and environmental demands of your system.
