The CNI 508N2 from AMETEK CTS is the first coupling/decoupling network available on the market to couple Surge onto shielded and unshielded high-speed communication lines with data rates up to 1,000MBit/s. Additionally, the CNI 508N2 can be used as a coupling/decoupling network to apply Burst- as well as Surge pulses to unshielded symmetrical interconnection lines. The CNI 508 N2 meets the requirements according Figure 11 and Figure 12 to the standards IEC 61000-4-5 (Ed. 3.0 :2014).

The CNI 508N2 is specially designed for the testing of high-speed communication lines. It allows data transfers up to 1,000 Mbit / s without affecting the signal. It also supports PoE and PoE + standard requirements as per IEEE 802.3af-2003 and IEEE 802.3at-2009.

The CNI 508N2 includes two surge pulse inputs. One for the direct coupling to lines and one for coupling to the cable shield (see tests to shielded cables as per IEC 61000-4-5).
