摘要
为实现下一代100 G接口在数据中心TOR中的应用和推广,介绍了DSFP MSA的相关规范,并给出了DSFP接口在交换机中硬件电路的参考设计和应用指导。文中以8.0 Tb/s带宽的PAM4交换芯片为例,提出了48个下行DSFP接口和8个上行QSFP-DD接口的1U TOR交换机的设计和应用实例,经过验证测试,该1 U交换机功能稳定可靠。文中介绍的相关设计方法和应用可以推广应用到其他类似产品中,特别对于DSFP相关的产品开发有参考价值。
In order to achieve the promotion and application of 100 G interface in Data⁃Center Switch TOR,the related specification of DSFP MSA is introduced,and provide the reference hardware⁃design and guide for DSFP interface in switch.Takes one 8.0 Tb/s bandwidth switch PAM4 as an example,this paper provides the design and application of 1U TOR switch with 48 downstream DSFP interface and 8 upstream QSFP-DD interface.The test result shows that this switch can work with stable and reliable performance.Those method and application introduced can be applied for other similar product and design,and has some reference value for DSFP product.
