Overview
3ctest CDN 418AFL8 unshielded asymmetric coupling/decoupling network is designed to test low speed communication line for damped oscillatory wave. It can be used to test 5MBit/s Ethernet. There is no need to extra protect AE because of high decoupling capacity to make sure test repeatability. Max. residual voltage on AE port is only 90V when the surge voltage is 2kV. It fully meets the requirements of IEC/EN 61000–4-18. Stable decoupling capacity and transmission rate, easy to use and compact size.
