Coupling/Decoupling Network for Unshielded Symmetric High-speed Communication Line

CDN 405T4

The CDN 405T4 unshielded symmetric high-speed communication line CDN, compliant with IEC 61000-4-5, GB/T 17626.5, is a professional CDN dedicated to lightning surge immunity tests on unshielded symmetrical high-speed communication lines. With 100 Mbit/s transmission rate, it delivers steady, loss-free communication throughout tests to replicate the EUT’s real working status, avoiding interference-caused misjudgments and guaranteeing consistent, precise test data.

The CDN 405T4 with excellent decoupling capability can protect auxiliary equipment from influence of interferences and cut system complexity and improve test efficiency greatly, meeting compliance verification requirements for industrial, railway and other sectors.

> Max. pulse voltage 6 kV

> Support data transmission rate up to 100 Mbit/s

> Support coupling waveform 1.2/50 μs, 8/20 μs

> Support EMC generators of all brands, quick connection without extra adaptation

> Superior decoupling, no extra auxiliary protection; plug-and-play to cut setup cost

> Support two coupling methods: 1-pair (2-wire) and 2-pair (4-wire) unshielded balanced lines, line-to-ground; 2-wire unshielded unbalanced lines, line-to-line

> External coupling elements and current-limiting resistor are replaceable
