Faraday Defense  EMC Ethernet Filter F1000-LAN

This shielded Ethernet filter is built for environments where network security, signal integrity, and electromagnetic control are critical. It’s ideal for use in secure facilities, government and defense installations, industrial environments, testing labs, and any application requiring controlled signal entry into shielded rooms or enclosures.

By preventing unwanted external interference and limiting signal leakage, it helps maintain reliable network performance while supporting strict electromagnetic compliance standards. Designed for engineers, system integrators, and facility managers, this solution provides a dependable way to bring Ethernet connectivity into protected spaces without compromising performance or security.

All 8 lines are individually filtered using a low cut-off frequency, high-order, high-attenuation, low-ripple filter design to ensure maximum signal clarity and minimal distortion. The unit also supports Power over Ethernet (PoE), delivering up to 15 watts per port. Housed in a custom-machined, conductive bead-blasted aluminum enclosure with a universal mounting pattern and standard RJ45 connector, it provides both electrical performance and durable, precision-built construction for demanding applications.
