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?
| 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

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
