IEEE802.3bj以及IEEE802.3bm定义了第二代100G。第二代100G和第一代100G的显著区别就是
单路电接口速率达到了25.78125Gbps
100Gbase-KR4:背板应用,传输的介质是PCB走线 电速率25.78125Gbpsx 4
100Gbase-CR4:铜缆应用,传输的介质有PCB走线和铜缆 电速率25.78125Gbpsx 4
100Gbase-SR4:光模块应用,短距多模光纤 电/光速率都为25.78125Gbpsx 4
以上数字的后缀都为最终传输媒介所要的通道数量,信号速率则为总带宽除以通道数量

Abstract
: 100 Gb/s Physical Layer (PHY) specifications and management parameters for operation
on electrical backplanes and twinaxial copper cables
are added by this amendment to
IEEE Std 802.3-2012.
This amendment also specifies optional Energy Efficient Ethernet (EEE) for
40 Gb/s and 100 Gb/s operation over electrical backplanes and copper cables.
Keywords: 100 Gb/s Ethernet, 100GBASE-CR10, 100GBASE-CR4, 100GBASE-KP4,
100GBASE-KR4, 40 Gb/s Ethernet, 40GBASE-CR4, 40GBASE-KR4, amendment, Auto-
Negotiation (AN), Backplane Ethernet, Energy Efficient Ethernet (EEE), Ethernet, Forward Error
Correction (FEC), IEEE 802.3™, IEEE 802.3bj™, Physical Medium Attachment (PMA) sublayer,

Important Notices and Disclaimers Concerning IEEE Standards Documents
IEEE documents are made available for use subject to important notices and legal disclaimers. These notices
and disclaimers, or a reference to this page, appear in all standards and may be found under the heading
“Important Notice” or “Important Notices and Disclaimers Concerning IEEE Standards Documents.”
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents
IEEE Standards documents (standards, recommended practices, and guides), both full-use and trial-use, are
developed within IEEE Societies and the Standards Coordinating Committees of the IEEE Standards
Association (“IEEE-SA”) Standards Board. IEEE (“the Institute”) develops its standards through a
consensus development process, approved by the American National Standards Institute (“ANSI”), which
brings together volunteers representing varied viewpoints and interests to achieve the final product.
Volunteers are not necessarily members of the Institute and participate without compensation from IEEE.
While IEEE administers the process and establishes rules to promote fairness in the consensus development
process, IEEE does not independently evaluate, test, or verify the accuracy of any of the information or the
soundness of any judgments contained in its standards.
IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and
expressly disclaims all warranties (express, implied and statutory) not included in this or any other
document relating to the standard, including, but not limited to, the warranties of: merchantability; fitness
for a particular purpose; non-infringement; and quality, accuracy, effectiveness, currency, or completeness of
material. In addition, IEEE disclaims any and all conditions relating to: results; and workmanlike effort.
IEEE standards documents are supplied “AS IS” and “WITH ALL FAULTS.”
Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there
are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to
the scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is approved and
issued is subject to change brought about through developments in the state of the art and comments
received from users of the standard.
In publishing and making its standards available, IEEE is not suggesting or rendering professional or other
services for, or on behalf of, any person or entity nor is IEEE undertaking to perform any duty owed by any
other person or entity to another. Any person utilizing any IEEE Standards document, should rely upon his
or her own independent judgment in the exercise of reasonable care in any given circumstances or, as
appropriate, seek the advice of a competent professional in determining the appropriateness of a given IEEE
standard.
IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO:
PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR
BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY,
WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR
OTHERWISE) ARISING IN ANY WAY OUT OF THE PUBLICATION, USE OF, OR RELIANCE UPON
ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE AND
REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.
