This connector system can handle signal paths that conform to the IEEE 802.3bj standard. Besides higher data rates, telecom/datacom vendors demand higher contact density with a lot of differential signal contacts /inch. The ERmet ZDHD system fulfills these needs, offering 14 contact rows/inch with six, or four, differential signal pairs/row. In total this is respectively 84 or 56 differential signal pairs/inch.

To reach this high signal density the pitch between the rows was reduced to only 1.8 mm while the pitch between the differential pairs within a row was reduced to 3.6 mm. A prerequisite of constructing a system of this size reduction is a downsized pressfit technology with 0.46 mm diameter hole. These miniaturised vias enable an optimised crosstalk behaviour. Robust alignment guides on male side walls support a reliable mating.
