CNI 508N1 - Coupling/decoupling assembly for unshielded and shielded high-speed communication lines
The EM TEST CNI 508N1 assembly is the first coupling/decoupling network available on the market to couple Surge onto unshielded and shielded high-speed communication lines with data rates up to 1,000MBit/s.
The CNI 508N1 assembly consists of a coupling network CN 508N1, a decoupling network CNI 508N1 and a protection equipment SPN 508N1 to limit the residual voltage at the AE side.
Additionally, the CNI 508N1 can be used as a coupling/decoupling network to apply Surge as well as Ringwave and Burst pulses to shielded lines.

Coupling Network for unshielded high-speed communication lines
The CN 508N1 is the coupling device including the matching resistors and the coupling devices to couple the 1.2/50us surge pulse up to 4kV on to max. 8 high-speed communication lines. The CN 508N1 also supports PoE and PoE+ standard requirements as per IEEE 802.3af-2003 and IEEE 802.3at-2009.

Surge Protection Network for unshielded and shielded high-speed communication lines
The SPN 508N1 is required to appropriately decouple the surge pulses from the auxiliary equipment. Its specific design allows the full data transfer up to 1GBit/s without causing signal degradation. The residual voltage at the AE port is limited to max. 10V@2kV surge voltage.

CDN for undshielded and shielded high-speed communication lines
The CNI 508N1 is a specifically designed CDN for testing high-speed communication lines. Its unique design allows data rates of up to 1,000MBit/s to be transmitted without degradation by the coupling/decoupling network. The decoupling network protects the auxiliary equipment limiting the residual voltage to max. 20V@2kV for common-mode surge test pulses.
Moreover, the CNI 508N1 fully supports PoE and PoE+ standard requirements as per IEEE 802.3.
The CNI 508N1 may also be used for testing shielded cables as per IEC/EN 61000-4-5, Fig. 16. It simplifies the test set-up and offers proper decoupling of the auxiliary equipment as well as a high safety for the operator as the surge is coupled through the CNI 508N1 rather than being directly applied to the metallic case of the DUT.
Additionally, the CNI 508N1 may also be used to couple Ringwave pulse (0.5us/100kHz) and burst pulses to shielded cables.

Test Set-up recommendation for unshielded high-speed communication lines
Coupling of the surge pulses is achieved by means of the CN 508N1 coupling network while the CNI 508N1 acts as the decoupling unit. For additional protection of the auxiliary equipment by reducing the residual voltage level the SPN 508N1 is used.

Test Set-up recommendations for PoE and PoE+
Using the SPN 508N1 Surge Protection Network to decouple the surge pulses from the auxiliary equipment directly influences the capabilities of the CN 508N1 and the CNI 508N1 to comply with the PoE and the PoE+ requirements. It is therefore recommended to install the PoE supply between the SPN 508N1 and the CNI 508N1 for proper operation of the PoE system.
