ERNI Electronics Expands its High-Speed Portfolio

ERmet ZDHD connectors enable data rates up to 25Gbps

Adelberg/Germany, May 02, 2011 - With the new ERmet ZDHD family, ERNI Electronics has developed a high-speed connector system, which is designed for data rates of up to 25 Gbps. In developing the new family, ERNI leveraged from its comprehensive expertise from the proven ERmet ZD family and the ERmet ZDplus connector system, a layout-compatible enhancement of ERmet ZD. In the case of the ZDHD components, HD stands for high density, as the new high-speed connectors offer 84 differential signal pairs per inch, whereas predecessor families only provided 40 pairs/inch. With this development, ERNI is addressing the needs of the industry for ever-higher signal density coupled with maximum performance.   ; e' e1 A$ z" B/ E ERmet ZDplus is based on the same mechanical design as the proven ERmet ZD, launched onto the market by ERNI Electronics together with Tyco back in 2001, with the same dimensions. To achieve even higher data rates of up to 15Gbps and to improve the crosstalk behaviour, ERNI Electronics has further optimised the signal routing and the press-fit termination of the female connectors. As the first product of the ERmet ZDplus family, an angled female connector in press-fit technology in the 4 pair configuration has been introduced. The ERmet ZDplus female connector is mating compatible with the ERmet ZD male connector. This means that existing backplane designs do not require any changes to the layout on the backplane side if the system is to be upgraded to the new connector. - c1 W- Z0 K$ J6 T  l% j: j0 k; tHigh-density extension 6 D' p3 [1 A) w+ S Many telecom/datacom manufacturers not only request ever-higher data rates but also a higher signal density with 80 differential signal pairs/inch. The new ERmet ZD/HD system caters to these requirements and offers 14 contact rows/inch (25.4 mm) with six differential signal pairs per row. Using ERmet ZDHD connectors, data rates of up to 25Gbps are possible. To this end, 84 signal pairs per inch for right-angle PCB applications are available. To achieve this high signal density, the pitch has been reduced between the rows to 1.8mm and the pitch between the differential pairs within a row to 3.6mm. The basis for this is provided by a miniaturised press-fit technology with a hole diameter of just 0.46mm. Robust alignment guides on the walls of the male connectors also ensure reliable mating. The ERmet ZD/HD connectors are initially available as 6-pair versions, with 2 and 4-pair versions being planned.

这样一来，几乎所有的连接器大厂都推出了速率能到25Gbps的连接器，计有：

25G实际上是有水分的。路程有长短，只要路程足够短，陡坡也是可能爬过去的。

25G下关键不是IL，而是ICR、RL。

doya

重点关注ICR、ILD等指标。

25G下关键不是IL，而是ICR、RL。

最关键的还是ICR，尤其是从SerDes扇出时的Xtalk, 这个的Characteristic和Qualify 是一个难点。

40G的连接器Molex的应该还有Impel吧。

这是2012年初的答复，在过去的一年，所有厂商的25G 连接器都发布了，我们也已全部测试完毕。
