Description
802.3ae
2002
10 Gbit/s Ethernet over fibre for LAN (10GBASE-SR, 10GBASE-LR,
10GBASE-ER, 10GBASE-LX4) and WAN (10GBASE-SW, 10GBASE-LW,
10GBASE-EW).
802.3ak
2004
10GBASE-CX4 10 Gbit/s Ethernet over twin-axial (InfiniBand type) cable.
802.3-2005
2005
A revision of base standard incorporating the prior amendments and errata.
802.3an
2006
10GBASE-T 10 Gbit/s Ethernet over copper twisted pair cable.
802.3ap
2007
Backplane Ethernet (1 and 10 Gbit/s over printed circuit boards).
802.3aq
2006
10GBASE-LRM 10 Gbit/s Ethernet over multimode fibre with enhanced
equalization.
802.3-2008
2008
A revision of base standard incorporating the 802.3an/ap/aq/as
amendments, two corrigenda and errata. Link aggregation moved to
802.1AX.
To support different 10GbE physical layer standards, many interfaces consist of a standard socket into
which different PHY modules may be plugged. Physical layer modules are not specified in an official
standards body but by multi-source agreements (MSAs) that can be negotiated more quickly. Relevant
MSAs for 10GbE include XENPAK (and related X2 and XPAK), XFP and SFP+. When choosing a PHY
module, a designer considers cost, reach, media type, power consumption, and size (form factor). A
single point-to-point link can have different MSA pluggable formats on either end (e.g. XPAK and SFP+)
as long as the 10GbE optical or copper interface (e.g. 10GBASE-SR) inside the pluggable is identical.
The Net2Edge Ltd. (TN) SFP+ modules are hot-pluggable (allows plugging in or unplugging a module
while the host board is powered). Note: Net2Edge Ltd.’ SFP+ modules fully comply with the Multi-
Sourcing Agreement (MSA). This compliance allows our SFP+ modules to be used in all other MSA
compliant SFP+ platforms. In addition, TN SFP modules are also compatible with all Cisco SFP+ based
routers and switches, as well as Cisco’s IOS software. TN SFP+ modules ARE NOT Cisco OEM brand
modules. For more information see

Most of the specifications developed by the SFF Committee have either been incorporated into standards
or adopted as standards by EIA (Electronic Industries Association), ANSI (American National Standards
Institute) and IEC (International Electrotechnical Commission). The SFF Committee activities support the
requirements of the storage industry, and it is involved with several standards. If you are interested in
participating or wish to follow the activities of the SFF Committee, the signup for membership and/or
documentation can be found at:

The complete list of SFF Specifications which have been completed or are currently being worked on by
the SFF Committee are at ftp://ftp.seagate.com/sff/SFF-8000.TXT. See also ftp://ftp.seagate.com/sff/SFF-
