802.3cd_D3p0是针对50G以太网标准的一个技术规范，由IEEE（电气和电子工程师协会）的局域网/城域网标准委员会制定。这个标准是IEEE 802.3系列标准的一个修订版，旨在定义在50Gbps、100Gbps和200Gbps速率下的媒体访问控制（MAC）参数、物理层（PHY）规格以及管理参数，以便于传输符合IEEE 802.3格式的数据帧。在通信领域，IEEE 802.3标准是定义以太网网络技术的核心规范，涵盖了MAC层协议、物理层接口和传输介质等方面。802.3cd是对原有标准的扩展，特别是在高速率传输方面，为数据中心、企业网络和电信应用提供了更高的带宽需求解决方案。这个标准的D3.0草案是在2017年11月13日发布的，是为初始赞助商投票阶段准备的。这个草案在发布后六个月内或下一个版本发布时（两者中先到者）到期。这意味着在此期间，标准可能还会根据反馈进行调整。 802.3cd标准的制定考虑了之前一系列802.3标准的修订，包括802.3bw、802.3by、802.3bq、802.3bp、802.3br、802.3bn、802.3bz、802.3bu、802.3bv、802.3-2015/Cor 1-2017、802.3bs、802.3cc、802.3cb等，这些修订版涵盖了不同速度和应用场景的以太网技术。由于这是一个未经批准的草案，其内容可能发生变化，并且不能用于任何符合性或合规性目的。只有正式批准的标准才能被用作设计、制造或认证的依据。尽管如此，这个草案对于那些关注以太网技术发展和未来网络架构规划的专业人士来说，仍然具有重要的参考价值。 50G以太网的实现涉及到多个技术挑战，包括信号完整性、功耗效率、光通信技术和多信道聚合等。802.3cd标准将定义如何在物理层实现这些高速率，例如，可能采用PAM4（四电平脉冲幅度调制）编码技术来提高数据传输效率，同时保持较低的功耗。此外，它还将规范MAC层如何与物理层交互，确保数据包的正确传输和错误处理。 802.3cd标准的制定是网络技术演进的重要一步，它推动了以太网技术向更高带宽、更低延迟的方向发展，满足了大数据、云计算和物联网等新兴应用的需求。随着技术的不断进步，50G以太网有望在数据中心互联、高性能计算和5G回传等领域发挥关键作用。

This document is an unapproved draft of a proposed IEEE Standard. As such, this document is subject to

change. USE AT YOUR OWN RISK! IEEE copyright statements SHALL NOT BE REMOVED from draft

or approved IEEE standards, or modified in any way. Because this is an unapproved draft, this document

must not be utilized for any conformance/compliance purposes. Permission is hereby granted for officers

from each IEEE Standards Working Group or Committee to reproduce the draft document developed by that

Working Group for purposes of standardization consideration by ISO/IEC. IEEE Standards Department

must be informed of the submission for consideration prior to any reproduction (stds.ipr@ieee.org

adoption of this document, in whole or in part, by another standards development organization, permission

must first be obtained from the IEEE Standards Department (stds.ipr@ieee.org

IEEE P802.3cd Task Force 13th November 2017

This is an unapproved IEEE Standards draft, subject to change.

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

Editor’s Note (to be removed prior to publication):

This front matter is provided for comment only. Front matter is not part of a published standard and is

therefore, not part of the draft standard. You are invited to review and comment on it as it will be included

in the published standard after approval.

One exception to IEEE style that is consciously used to simplify the balloting process is the numbering of

the front matter. Instead of the front matter being lower case Roman numeral page numbers, with the draft

restarting at 1 with Arabic page numbers, balloted front matter and draft are numbered consecutively with

Arabic page numbers.

Draft Amendment to IEEE Std 802.3-2015 IEEE Draft P802.3cd/D3.0

IEEE P802.3cd Task Force 13th November 2017

This is an unapproved IEEE Standards draft, subject to change.

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.

Translations

The IEEE consensus development process involves the review of documents in English only. In the event

that an IEEE standard is translated, only the English version published by IEEE should be considered the

approved IEEE standard.

Official statements

A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board

Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its

committees and shall not be considered to be, or be relied upon as, a formal position of IEEE. At lectures,

symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall

make it clear that his or her views should be considered the personal views of that individual rather than the

formal position of IEEE.

Comments on standards

Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of

membership affiliation with IEEE. However, IEEE does not provide consulting information or advice

pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a

proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a

consensus of concerned interests, it is important that any responses to comments and questions also receive

the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and

Standards Coordinating Committees are not able to provide an instant response to comments or questions

except in those cases where the matter has previously been addressed. For the same reason, IEEE does not

respond to interpretation requests. Any person who would like to participate in revisions to an IEEE

standard is welcome to join the relevant IEEE working group.

Comments on standards should be submitted to the following address:

Secretary, IEEE-SA Standards Board

445 Hoes Lane

Piscataway, NJ 08854 USA

Laws and regulations

Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with the

provisions of any IEEE Standards document does not imply compliance to any applicable regulatory

requirements. Implementers of the standard are responsible for observing or referring to the applicable

regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not

in compliance with applicable laws, and these documents may not be construed as doing so.
