Coupling/Decoupling Network for Damped Oscillatory Waves Testing on Unshielded Symmetrical High-Speed Communication Lines

CDN 418TH8

The CDN 418TH8 is a coupling/decoupling networks for damped oscillatory waves testing on unshielded symmetrical high-speed communication lines complies with IEC 61000-4-12, IEC 61000-4-18, GB/T 17626.12 and GB/T 17626.18.

The CDN 418TH8 is applicable to tests for ISDN and 10/100/1000 Mbit/s Ethernet. Its strong decoupling capability protects AE from damped oscillatory waves and ensures test repeatability. At a damped oscillatory test voltage of 2 kV, the max. residual voltage at the AE port is only 90 V, and no additional decoupling components are required.

This is the first domestic damped oscillatory wave coupling decoupling network supporting high-speed communication up to 1,000 Mbit/s. It delivers stable decoupling performance and transmission speed, and features compact size for easy carrying and operation.
