I-PEX正在为112 GBPS PAM4应用程序开发新的解决方案：Leapwire™/ Dualine™系列，板到板连接器，用于112 Gbps PAM4。点击here观看我们的产品视频。

发展背景: In recent years, infrastructure telecommunication, such as servers and switches, have become increasingly faster in the enterprise market. The challenge is that conventional PCB trace transmission have large insertion losses with limited transmission distance.

A co-package system also faces the challenge of high-density packaging. I-PEX has started development of our new LEAPWIRE™/DUALINE™ series 112 Gbps PAM4 using high-speed twinax cables and 112 Gbps PAM4 board-to-board connection to solve these problems. These products will be used for transmission between chips inside equipment and connection to I/O connectors. LEAPWIRE™ is the new high-speed transmission jumper solution, DUALINE™ series is the actual connector.

Challenge:The problem is that the existing board transmission pattern (shown in Fig. 1) has high insertion loss in the PCB trace transmission. Also, because of the large connector size of the general jumper harness, the connector is placed far from the heat sink, and the I/O connector is connected through the board, resulting in a large transmission loss (shown in Fig. 2). In our proposed design (shown in Fig. 3), the connector height has a low profile, allowing for placement under the heat sink, putting it closer to the ASIC. Direct connection to I/O connectors is now possible, which helps reduce transmission loss. The small size of the connector also supports airflow measures.

I-PEX LEAPWIRE™ (Twinax Cable) can transmit approximately 10.3 times farther in the 28 GHz band than PCB transmission.

共包装趋势：共包装旨在应对带宽和功耗的挑战。这是一种先进的混合安装技术，将电子组件与单个基板包上的IC相结合。在下一步中，可以预见，光学和电子开关将在单个基板软件包上组合。减少功耗和热效应，同时使用该技术减少足迹已成为高速支持高速网络的挑战。该系统还允许在失败时更换软件包本身，从而提供更大的设计灵活性。如前所述，更快，更有效的传输和更高的密度包装是挑战。需要较小的连接器和跳线解决方案，这些解决方案需要高速传输。

正在开发以下新的I-PEX解决方案来解决这些问题。
