对应SFP+的电气接口叫做SFI。 XFI接口先于SFI接口出现。电气特性上,由于SFP+模块内部没有CDR,可以预见SFI的电气特性要求会比XFI来的更严格一些,这个可以从接下来的介绍的眼图和抖动指标要求中可以清楚的看出来。 可以看出B点处的眼图模板,XFI比SFI的要求更宽松,这是因为XFP光模块内部接收端集成的CDR,它可以承担宽松...
LAN和DC应用主要采用三种主要协议：SR（短波长、短距离）、LR（长波长、长距离）与ER（超长波长、扩展范围）。IEEE 802.3-2008规范详细定义了10GBASE-R PHY与Ethernet MAC/RS之间的XGMII接口。此PHY可利用XFI或SFI电气规范直接连接至XFP或SFP+设备。10GBASE-R是专为光模块LAN应用设计的协议，如光路由...
符合SFI标准的SerDes/PHY应该能够完全符合XFI规范,但专为XFI设计的较旧的SerDes/PHY可能无法满足SFI的所有电气规格。特别是SFF-8431中规定的主机PHY/重定时器抖动和应力输入要求比XFP MSA的要求更严格。在10GBASE-KR方面,此规范用于电气背板应用,如使用Stratix V收发器的刀片服务器。IEEE 802.3ap-2007规范要求每个...
