Building on VeEX’s portable network testing experience, the MTX642 is a compact, dual-400 G handheld test solution. With 400G dual ports and dual-port interfaces from 1G to 200G, it supports QSFP-DD 400G and other common transceiver form factors, AOCs, and DACs. Optimized for fast field operations, the MTX642 goes from power-up to dual 400GE testing in under two minutes, making it well-suited for time-critical tasks such as troubleshooting transceivers, network equipment verification, installation, maintenance, and commissioning. As industry-wide adoption of 400GE grows, its intuitive graphical user interface (GUI) and predefined configurations streamline testing, enabling users to run advanced tests immediately with application-specific test applications.
