Fischer KEYSTONE reliability and ease of use are augmented by improved interoperability and extensive device integration capabilities. Since its inception in March 2023, Fischer Connectors’ R&D team has created numerous additional cable alternatives to offer seamless communication, increased ergonomics, and multi-device interoperability for dismounted operations in the Nett Warrior compatibility environment.

Fischer Connectors’ Swiss-engineered MIL-SPEC solution includes a broader range of cables compatible with Nett Warrior and NATO STANAG 4695/4851 interfaces via Fischer UltiMate 80 connectors. It provides a competitive solution in accordance with the US Army’s Next Generation Hub (NGH) standards.
The new general-purpose, power, radio, EUD, and device cables provide plug-and-play connectivity, compatibility, and interoperability across the battlefield management ecosystem.
Olivier Thormann, Product Manager at Fischer Connectors for Fischer KEYSTONE, provides input from customers worldwide who have field-tested the Swiss power and data hub. “Soldiers say it is reliable and simple and does exactly what it’s expected to do. They already know how to use it – they clip it on, plug it in, and it just works.”

The cable catalog includes alternatives for linking EUDs, batteries, radio systems, and devices like helmet cameras and target acquisition or range-finding systems into soldier-worn equipment. It provides a comprehensive tactical networking solution designed to meet the tough needs of modern warfare.
“KEYSTONE meets the growing demand for easy, reliable connectivity and interoperability of soldier-worn digital equipment in dynamic operational environments,” says Thormann.
“Our cable portfolio addresses essential tactical connectivity needs by combining lean ergonomics with the seamless integration of key devices and C4ISR communication systems. Customers trust Fischer Connectors’ hubs as robust plug-and-play solutions that enable real-time communication, intelligence gathering, and precision engagement.”
The enlarged portfolio of standard and customizable cable assemblies compatible with the Nett Warrior and NATO STANAG 4695/4851 standards comprises extensions, adapters, and interconnects in four categories.

- General purpose cables: USB 2.0, RS-232, Ethernet, Nett Warrior type and BB-2590 batteries, right-angle overmolded cable options
- Radio cables: Silvus, Bittium, L3 Harris, DTC CODAN, Thales
- EUD cables: Standard USB-C right-angle assemblies compatible with Juggernaut cases
- Devices cables: Designed for the MOHOC® 2 IP Camera and Safran Vectronix’s target acquisition and range-finding systems (PLRF25C, MOSKITO TI, STERNA True North Finder), among others available upon request.
KEYSTONE cable assemblies can be customized to meet specific requirements. “Customization is one of our company’s core strengths,” says Thormann. “Our technical teams collaborate closely with customers to ensure our solutions align precisely with their operational needs and expectations.”Â
Fischer UltiMate 80: the complete range of Nett Warrior-compatible connectors
The Fischer UltiMate 80 connectors used in KEYSTONE are Nett Warrior-compatible and part of Fischer connections’ flagship collection of ultra-rugged, MIL-SPEC connectors, the Fischer UltiMate collection.
The UltiMate 80 product line has recently expanded to incorporate a new panel plug. This completes a product portfolio capable of addressing all of the integration requirements of users looking for devices that can operate in the most demanding situations.Â
A competitive edge in Soldier Modernization
Fischer Connectors’ Swiss-engineered KEYSTONE hub, available with 4 or 6 ports, provides a competitive, ready-to-deploy solution that meets the requirements of the United States Army’s Next Generation Hub (NGH).
KEYSTONE is designed to be simple and efficient, allowing soldiers to control data and power flows across sights, sensors, night vision devices, radios, and other digital equipment. It connects teams and commanders, powers mission-critical devices, and enables real-time situational awareness and speedier decision-making in complex operating environments.

Fischer KEYSTONE provides USB 2.0 and SMBus data channels, as well as power distribution of up to 100 W (5 A max), all via a lightweight, ergonomic interface. Fischer KEYSTONE 6 includes a simple power management program, which may be run as a standalone application or as an ATAK plug-in on the soldier’s EUD.
KEYSTONE, built with Fischer Connectors’ established MIL-SPEC technology, offers rugged durability, a compact form factor, and IP68 sealing. It is a complete networking platform that fits the stringent requirements of troop modernization efforts, such as US Army 2030.
