The new Teseq coupling/decoupling network (CDN) model HSS-2 is designed for surge testing of balanced unshielded wire pairs. Examples include Ethernet 1, 2, and 4 pair communication buses and coupling is achieved via a 40 ohm resistive impedance in series with capacitive coupling elements. The Teseq CDN-HSS-2 is suitable for 10, 100, and 1000 Base T as well as for power-over-Ethernet (PoE). The Teseq CDN-HSS-2 is safe to use and even with a surge test voltage of 2 kV, auxiliary equipment is subject to 65 volts maximum. The decoupling network provides testing in accordance with IEC 61000-4-5 (edition 3/77/67A/CD2012-05) and provides a surge pulse shape for the equipment under test (EUT) that is independent of auxiliary equipment. Insertion loss for the CDN is typically 9 dB at 100 MHz. This coupling network can be used with any surge generator for example the Teseq NSG 3060, NSG 3040 or the Schaffner Modula Series.
