10 Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard.
The Nexus B22FEX offer 16 x 10 Gbase-KR internal 10 Gbit/s link to each blade-server interface and up to 8 SFP+ ports for uplink with a Nexus 5010, 5548 or 5596 switch. The maximum distance between the FEX and the mother-switch is 3 kilometer when it is only used for TCP/IP traffic and 300 meter when carrying also FCoE traffic.
Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z , and required optical fiber . 802.3z is commonly referred to as 1000BASE-X, where -X refers to either -CX, -SX, -LX, or (non-standard) -ZX.
[10] [11] These modules were preceded by Medium Attachment Units connected via Attachment Unit Interfaces to switches [12] [13] and have evolved over time: the first modules were Gigabit interface converters, followed by XENPAK modules, SFP modules, XFP transceivers, SFP+ modules, QSFP, [14] QSFP-DD, [15] and OSFP [16] modules. Pluggable ...
10 Gigabit Attachment Unit Interface (XAUI / ˈ z aʊ i / ZOW-ee) is a standard for extending the XGMII (10 Gigabit Media Independent Interface) between the MAC and PHY layer of 10 Gigabit Ethernet (10GbE) defined in Clause 47 of the IEEE 802.3 standard.
The original QSFP document specified four channels carrying Gigabit Ethernet, 4GFC (FiberChannel), or DDR InfiniBand. [52] 40 Gbit/s (QSFP+) QSFP+ is an evolution of QSFP to support four 10 Gbit/s channels carrying 10 Gigabit Ethernet, 10GFC FiberChannel, or QDR InfiniBand. [53] The 4 channels can also be combined into a single 40 Gigabit ...
