多源协议(MSA)往往被用作事实上的标准。它对包含SFP、SFP+和QSFP-DD等可互操作产品的竞争市场给予了考虑。

SFP

SFP/SFP+(小型可插拔式)是一种可热插拔的紧凑型光学模块收发器,常用于电信和数据通信应用。

标准SFP标识

Samtec的SFP+电缆系统包含一个安装在面板上的连接器和用于高速应用的跳线电缆。

SFP无源跳线

QSFP

与SFP/SFP+类似,QSFP通常在光纤上使用x4通道配置。常见应用包括网络硬件之间的接口连接。

qsfp

Samtec的Flyover® QSFP系统通过在有损PCB材料上飞传关键高速信号,以及通过超低偏斜双芯电缆直连到面板,可提高信号完整性和架构灵活性。这一超高密度设计包含了通过压接端子的边带信号来帮助增加气流,并且多种“终端 2”选项可最大化实现设计灵活性。

QSFP-DD

随着先进的ASIC和FPGA解决方案进入市场,能够克服QSFP局限性的下一代模块需要拥有每通道50 Gbps以上的性能。新的QSFP-DD标准关注于突破前面板上和系统之间的数据速率瓶颈。

While Samtec started as a connector company with a focus on two-piece, pin-and-socket board stacking systems, High-Speed Board Stacking connectors and High-Speed Cable Assemblies now make up a significant portion of our sales. To support development in this area, in December of 2...
In the manufacturing world there are standards for just about everything, and they all are typically there to ensure a product can perform as expected for the end application. Among these standards is IPC-A-610 covering solder joints for varying types of connector termination sty...
New Year’s resolutions. Many of us make them, whether it’s to continue a good habit, change a bad one or accomplish a new goal, improvement is the focus. The hardest part of this process is the time between making the plan and accomplishing it. Wouldn’t it be nice if we could jus...
2019 was a fun year for Samtec.com. We’re in a great place right now where we get to maintain current content and features while we’re building a lot of new stuff as well. The website is becoming more mature, but still developing rapidly. If you missed it, here is a look back at ...
While air cooling is still a commonly used method to cool data centers, the industry is seeing HPC, AI, and scientific computing market leaders investigating either conduction cooling, or full-scale immersion cooling, for their next generation designs. In this video from SuperCom...
