EMP Kit

EMP Protection Kit for the ACTIV 10G

The ACTIV 10G EMP Kit is an accessory for the ACTIV 10G that adds electromagnetic pulse protection to Ethernet connections requiring hardened infrastructure. An EMP surge suppressor rated to MIL-STD-188-125 mounts inside an outdoor junction box on the exterior face of the shield wall. The DJM Universal Mounting System penetration stub originates at the ACTIV 10G filter body on the interior side, threads through the enclosure wall, and terminates inside the junction box secured by a single brass flange nut. Standard penetrations of 1″, 3″, 9″, and 12″ accommodate wall thicknesses from 1/8 inch to over 11 inches. Custom lengths available for any wall thickness. Surge suppressor waveform characteristics and protection levels can be modified for specific application requirements. Maximum data rate is 1 Gbps. Available by special order only. Made in the USA.

100dB Shielding Effectiveness.
EMP Protection Kit.

The ACTIV 10G EMP Kit delivers the same 100dB shielding effectiveness as the standard ACTIV 10G, with an EMP surge suppressor added to the signal path. The DSP engine actively reconstructs Ethernet signals without interference while the surge suppressor handles E1 and E2 electromagnetic pulse events. No signal leakage. No latency. No impact on network performance under normal operating conditions. Maximum data rate is 1 Gbps due to surge suppressor limitations.

The outdoor junction box mounts flush to the outside face of the shield wall. The DJM Universal Mounting System penetration stub originates at the ACTIV 10G filter body on the inside, threads through the shield wall, and terminates inside the junction box with a single brass flange nut. Standard penetrations of 1″, 3″, 9″, and 12″ accommodate wall thicknesses from 1/8 inch to over 11 inches. Custom lengths available for any wall thickness.

EMP / HEMP Protection
EMP surge suppressor rated to survive E1 (5kA, 20/500ns) and E2 (50A, 1.5/3000µs) pulses per MIL-STD-188-125. Tested to HEMP and lightning. Powered from inside the enclosure.
Military-Grade Construction
Machined from solid aluminum with electroless plated nickel finish. ESD and transient voltage suppressors, gas discharge tubes, and current limiters on all signal lines. Built for harsh environments and long service life.
Universal Mounting System
Mounts to any RF shielded enclosure or shielded room from any manufacturer. Standard penetration lengths of 1″, 3″, 9″, and 12″ accommodate wall thicknesses from 1/8 inch to over 11 inches. Custom lengths available for any wall thickness.
Proprietary DSP Technology
Actively reconstructs Ethernet signals at line rate without conducted or radiated EMI. No latency, no signal distortion, and invisible to network negotiation at any supported data rate from 10Mbps to 1Gbps.
