作用是什么？

used for both telecommunication and data communications applications

电信号和数据信息的转换

仅仅用以太网上

SFP transceivers exist supporting SONET,Gigabit Ethernet,Fibre Channel,and other communications standards.?

并不仅仅在IP网络上使用，同样会出现在光纤网络上。（FcoE)

在Vblock 中涉及的型号: 主要就是 SFP+

疑问：在SFP两段分别连接的信号是什么类型

光纤信号 ---SFP （Nexus）---IP信号

SFP	1 Gpbs
SFP+	10 Gpbs

What Are The Differences Between SFP,SFP+,XFP,QSFP/QSFP+,CFP and QSFP28?

http://www.fiber-optic-transceiver-module.com/what-are-the-differences-between-sfp-sfp-xfp-qsfpqsfp-cfp-and-qsfp28.html

SFP	small form-factor pluggable for short,is a compact,hot-pluggable transceiver module used for both telecommunication and data communications applications	?
SFP+	SFP+ is an enhanced version of the SFP that supports data rates up to 10 Gbit/s	?
QSFP/QSFP+	?	?

如何在log文件和live WebEx 中查询SFP的状态？

Identify the SFP PID on both components (Fabric Interconnect,Nexus switch) with the following NX-OS command:

# show interface ethX/X transceiver details

EthernetX/X

Physical Specifications

SFP+ Optics

Cisco UCS products support 10 Gigabit Ethernet SFP+ copper Twinax cables for short distances and SFP+ optics for longer distances. SFP+ has several advantages compared to other 10 Gigabit Ethernet connectivity options,including:

●???Small 10 Gigabit Ethernet form factor

●???Optical interoperability with XENPAK,X2,and 10 Gigabit Small Form-Factor Pluggable (XFP) interface types

●???Low power consumption

●???Hot-swappable device

Environment

●???Physical (height x width x depth): 7.64 x 1.36 x 7.2 in

●???Operating temperature: 32 to 104°F (0 to 40°C)

●???Nonoperating temperature: -40 to 158°F (-40 to 70°C)

●???Humidity: 5 to 95% (noncondensing)

●???Altitude: 0 to 10,000 ft (0 to 3000m)

Weight

●???2.5 lb (1.134 kg); Weight similar for Cisco UCS 2208XP and 2204XP IOMs
