Industrial Ethernet networks serve as the backbone for many automation control systems. Cables, whether copper or fiber optic, are a significant source of downtime in these time-sensitive industrial networks. Even losing a few data packets in a short time can lead to a computer shutdown. This risk is particularly pronounced in industrial and manufacturing environments where network cables are subjected to vibration, bending, moisture, temperature fluctuations, and electromagnetic interference (EMI) from motor drives and other devices. Fluke Networks offers a range of robust, high-quality industrial Ethernet tools and testers that enable facility electricians and control engineers to quickly identify cable faults.
