Power, latency and cost. The three horsemen of Artificial intelligence (AI) and Machine Learning (ML) data center interconnects. Each new generation of interconnect drives a lower mW/Gbps and dollar/Gbps. Power consumption is not just about data center operating expenses. It is also about sustainability.

在 2018 年进行了大量演示和 alpha 模块测试之后，双密度版本的四通道小型可插拔 (QFSP) 多源协议 (MSA) 模块标准有望成为新线卡的规则。QSFP-DD 热潮的隐含意义不是模块本身的物理特性，而是转向先进信令方法的趋势。十年前，QSFP28 的问世预示着使用 NRZ 信令的 25Gbps 电通道即将占据主导地位。如今，QSFP-DD 及其更庞大的表亲 —— 八进制 SFP 或 OSFP ，都使用 PAM4 信令。其用得最多的是 50Gbps 通道。但 QSFP-DD 足够灵活，可以在各种实施中使用八通道接口：25G x 8 用于 200Gbit 以太网，50G x 8 用于 400Gbit 以太网，可能还有一些早期的 100G x 8 用于预标准 800Gbit 以太网。

The 44th installment of the European Conference on Optical Communication (ECOC) Exhibition recently concluded in Rome, Italy. At the conference, Semtech® featured several products for the critical hyper-scale data center and 5G wireless markets. The technologies demonstrated by Semtech from its diverse portfolio of Optical solutions include the ClearEdge® CDR platform for low-cost 25G SFP28 modules that will be an essential component of the 5G infrastructure build out. Additionally, Semtech demonstrated its new line of Tri-Edge CDRs and FiberEdge™ linear Physical Media Dependent (PMD) devices that will help drive current Cloud data center build outs.
