This high speed backplane connector system was developed to meet the electrical requirements in designs with differential, lowvoltage signals and data rates beyond 10 Gbit/s. ERmet zeroXT has a very low Crosstalk level, minimal skew, good routing properties (simple conductor track routing), a reliable dual beam female contact design, different contact levels, and a robust housing. The optimized contact grid (2.5mm) allows for effective and flexible routing. Every differential signal pair is closely coupled with the ground signals to ensure a controlled impedance. Each wafer is enclosed by a shield plate. In addition, all differential signal pairs on the male connector are shielded by C-shaped shields.
