The CDN 405AF8 unshielded asymmetric coupling/decoupling network is designed for surge testing on low-speed communication lines (up to 10 MBit/s Ethernet speed). There is no need for extra protection of AE because of high decoupling capacity of CDN 405AF8 to make sure test repeatability. Max. residual voltage on AE port is only 90 V when the surge voltage is 2 kV. It fully meets the requirements of figure 9 in IEC/EN 61000 - 4 – 5: 2017. It also boasts stable decoupling capacity and transmission rate, easy to operate and compact size.
Features：
> Data rate up to 10 MBit/s;
> Test output to 1 pair, 2-pair or 4-pair communication line;
> No need to extra protect AE;
> Replaceable current-limiting resistors;
> Compatible with the output port of other company’s generators for communication test;
