MIL-GM / MIL-10GM

Time Server and L2/L3 Military Switch Router

Overview

The MIL-GM and MIL-10GM series are military-certified time servers that take full advantage of SOC-E’s advanced and well-known synchronization technology to ensure reliable, continuous and accurate timing in mission-critical applications. The switching electronics are implemented in a high-performance FPGA, allowing the devices to be fully customised to each customer’s specific requirements.

This MOTS approach, based on a field-proven COTS solution to minimize project risk, results in a SWaP interoperable all-in-one device, that combines time server and bridging functionality with switching, routing, firewall and edge computing capabilities in a single hardware platform.

With fully customisable external network connectivity and a lightweight and compact MIL-STD-810G certified chassis, the MIL-GM/MIL-10GM series can adapt to almost any situation and meet the requirements of a Digital Backbone (DBB) in the most demanding military programmes.
