Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical activity.

ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the

work.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for

the different types of ISO/IEC documents should be noted. This document was drafted in accordance

with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or

www.iec.ch/members_experts/refdocs).

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating

Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its

standards through a consensus development process, approved by the American National Standards

Institute, which brings together volunteers representing varied viewpoints and interests to achieve the

final product. Volunteers are not necessarily members of the Institute and serve without compensation.

While the IEEE administers the process and establishes rules to promote fairness in the consensus

development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the

information contained in its standards.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details

Important Notices and Disclaimers Concerning IEEE Standards
Documents

IEEE Standards documents are made available for use subject to important notices and legal disclaimers.

These notices and disclaimers, or a reference to this page (https://standards.ieee.org/ipr/disclaimers.html),

appear in all standards and may be found under the heading “Important Notices and Disclaimers Concerning

IEEE Standards Documents.”
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating

Committees of the IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards

through an accredited consensus development process, which brings together volunteers representing varied

viewpoints and interests to achieve the final product. IEEE Standards are documents developed by

volunteers with scientific, academic, and industry-based expertise in technical working groups. Volunteers

are not necessarily members of IEEE or IEEE SA, 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 completeness 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. In

addition, IEEE does not warrant or represent that the use of the material contained in its standards is free

from patent infringement. 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: THE
NEED TO PROCURE 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.

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 is 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, nor 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 the presenter's views should be considered the personal views of that individual rather than

the formal position of IEEE, IEEE SA, the Standards Committee, or the Working Group.

Comments on standards

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

membership affiliation with IEEE or IEEE SA. However, IEEE does not provide interpretations,

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 evaluating comments or in revisions to an IEEE standard is welcome

to join the relevant IEEE working group. You can indicate interest in a working group using the Interests tab

in the Manage Profile & Interests area of the IEEE SA myProject system. An IEEE Account is needed to

access the application.
Comments on standards should be submitted using the Contact Us form.
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 constitute 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.

Data privacy

Users of IEEE Standards documents should evaluate the standards for considerations of data privacy and

data ownership in the context of assessing and using the standards in compliance with applicable laws and

regulations.
Copyrights

IEEE draft and approved standards are copyrighted by IEEE under US and international copyright laws.

They are made available by IEEE and are adopted for a wide variety of both public and private uses. These

Copyright © 2021 IEEE. All rights reserved.
---------------------- Page: 7 ----------------------
ISO/IEC/IEEE 8802-3:2021/Amd.14:2022(E)

include both use, by reference, in laws and regulations, and use in private self-regulation, standardization,

and the promotion of engineering practices and methods. By making these documents available for use and

adoption by public authorities and private users, IEEE does not waive any rights in copyright to the

documents.
Photocopies

Subject to payment of the appropriate licensing fees, IEEE will grant users a limited, non-exclusive license

to photocopy portions of any individual standard for company or organizational internal use or individual,

non-commercial use only. To arrange for payment of licensing fees, please contact Copyright Clearance

classroom use can also be obtained through the Copyright Clearance Center.
Updating of IEEE Standards documents

Users of IEEE Standards documents should be aware that these documents may be superseded at any time

by the issuance of new editions or may be amended from time to time through the issuance of amendments,

corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the

document together with any amendments, corrigenda, or errata then in effect.

Every IEEE standard is subjected to review at least every 10 years. When a document is more than 10 years

old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of

some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that

they have the latest edition of any IEEE standard.

In order to determine whether a given document is the current edition and whether it has been amended

through the issuance of amendments, corrigenda, or errata, visit IEEE Xplore or contact IEEE. For more

information about the IEEE SA or IEEE's standards development process, visit the IEEE SA Website.

Errata

Errata, if any, for all IEEE standards can be accessed on the IEEE SA Website. Search for standard number

and year of approval to access the web page of the published standard. Errata links are located under the

Additional Resources Details section. Errata are also available in IEEE Xplore. Users are encouraged to

periodically check for errata.
Patents
IEEE Standards are developed in compliance with the IEEE SA Patent Policy.
IMPORTANT NOTICE

IEEE Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure

against interference with or from other devices or networks. IEEE Standards development activities consider

research and information presented to the standards development group in developing any safety

recommendations. Other information about safety practices, changes in technology or technology

implementation, or impact by peripheral systems also may be pertinent to safety considerations during

implementation of the standard. Implementers and users of IEEE Standards documents are responsible for

determining and complying with all appropriate safety, security, environmental, health, and interference

protection practices and all applicable laws and regulations.

Introduction

This introduction is not part of IEEE Std 802.3cp-2021, IEEE Standard for Ethernet—Amendment 14: Bidirectional

10 Gb/s, 25 Gb/s, and 50 Gb/s Optical Access PHYs.

IEEE Std 802.3™ was first published in 1985. Since the initial publication, many projects have added

functionality or provided maintenance updates to the specifications and text included in the standard. Each

IEEE 802.3 project/amendment is identified with a suffix (e.g., IEEE Std 802.3ba™-2010).

The half duplex Media Access Control (MAC) protocol specified in IEEE Std 802.3-1985 is Carrier Sense

Multiple Access with Collision Detection (CSMA/CD). This MAC protocol was key to the experimental

Ethernet developed at Xerox Palo Alto Research Center, which had a 2.94 Mb/s data rate. Ethernet at

10 Mb/s was jointly released as a public specification by Digital Equipment Corporation (DEC), Intel and

Xerox in 1980. Ethernet at 10 Mb/s was approved as an IEEE standard by the IEEE Standards Board in 1983

and subsequently published in 1985 as IEEE Std 802.3-1985. Since 1985, new media options, new speeds of

operation, and new capabilities have been added to IEEE Std 802.3. A full duplex MAC protocol was added

in 1997.

Some of the major additions to IEEE Std 802.3 are identified in the marketplace with their project number.

This is most common for projects adding higher speeds of operation or new protocols. For example,

IEEE Std 802.3u™ added 100 Mb/s operation (also called Fast Ethernet), IEEE Std 802.3z added

1000 Mb/s operation (also called Gigabit Ethernet), IEEE Std 802.3ae added 10 Gb/s operation (also called

10 Gigabit Ethernet), IEEE Std 802.3ah™ specified access network Ethernet (also called Ethernet in the

First Mile) and IEEE Std 802.3ba added 40 Gb/s operation (also called 40 Gigabit Ethernet) and 100 Gb/s

operation (also called 100 Gigabit Ethernet). These major additions are all now included in and are

superseded by IEEE Std 802.3-2018 and are not maintained as separate documents.

At the date of IEEE Std 802.3cp-2021 publication, IEEE Std 802.3 was composed of the following

documents:
IEEE Std 802.3-2018

Section One—Includes Clause 1 through Clause 20 and Annex A through Annex H and Annex 4A.

Section One includes the specifications for 10 Mb/s operation and the MAC, frame formats and service

interfaces used for all speeds of operation.

Section Two—Includes Clause 21 through Clause 33 and Annex 22A through Annex 33E. Section

Two includes management attributes for multiple protocols and speed of operation as well as

specifications for providing power over twisted pair cabling for multiple operational speeds. It also

includes general information on 100 Mb/s operation as well as most of the 100 Mb/s Physical Layer

specifications.

Section Three—Includes Clause 34 through Clause 43 and Annex 36A through Annex 43C. Section

Three includes general information on 1000 Mb/s operation as well as most of the 1000 Mb/s Physical

Layer specifications.

Section Four—Includes Clause 44 through Clause 55 and Annex 44A through Annex 55B. Section

Four includes general information on 10 Gb/s operation as well as most of the 10 Gb/s Physical Layer

specifications.

Section Five—Includes Clause 56 through Clause 77 and Annex 57A through Annex 76A. Clause 56

through Clause 67 and Clause 75 through Clause 77, as well as associated annexes, specify subscriber

access and other Physical Layers and sublayers for operation from 512 kb/s to 10 Gb/s, and defines

---------------------- Page: 12 ----------------------
ISO/IEC/IEEE 8802-3:2021/Amd.14:2022(E)

services and protocol elements that enable the exchange of IEEE Std 802.3 format frames between

stations in a subscriber access network. Clause 68 specifies a 10 Gb/s Physical Layer specification.

Clause 69 through Clause 74 and associated annexes specify Ethernet operation over electrical

backplanes at speeds of 1000 Mb/s and 10 Gb/s.

Section Six—Includes Clause 78 through Clause 95 and Annex 83A through Annex 93C. Clause 78

specifies Energy-Efficient Ethernet. Clause 79 specifies IEEE 802.3 Organizationally Specific Link

Layer Discovery Protocol (LLDP) type, length, and value (TLV) information elements. Clause 80

through Clause 95 and associated annexes include general information on 40 Gb/s and 100 Gb/s

operation as well the 40 Gb/s and 100 Gb/s Physical Layer specifications. Clause 90 specifies Ethernet

support for time synchronization protocols.

Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical activity.

ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the

work.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO/IEC documents should be noted. This document was drafted in accordance with

the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or

www.iec.ch/members_experts/refdocs).

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating

Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its

standards through a consensus development process, approved by the American National Standards

Institute, which brings together volunteers representing varied viewpoints and interests to achieve the

final product. Volunteers are not necessarily members of the Institute and serve without compensation.

While the IEEE administers the process and establishes rules to promote fairness in the consensus

development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the

information contained in its standards.

Important Notices and Disclaimers Concerning IEEE Standards
Documents

IEEE Standards documents are made available for use subject to important notices and legal disclaimers.

These notices and disclaimers, or a reference to this page (https://standards.ieee.org/ipr/disclaimers.html),

appear in all standards and may be found under the heading “Important Notices and Disclaimers Concerning

IEEE Standards Documents.”
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating

Committees of the IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards

through an accredited consensus development process, which brings together volunteers representing varied

viewpoints and interests to achieve the final product. IEEE Standards are documents developed by

volunteers with scientific, academic, and industry-based expertise in technical working groups. Volunteers

are not necessarily members of IEEE or IEEE SA, 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 completeness 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. In

addition, IEEE does not warrant or represent that the use of the material contained in its standards is free

from patent infringement. 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: THE
NEED TO PROCURE 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.

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 is 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, nor 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 the presenter's views should be considered the personal views of that individual rather than

the formal position of IEEE, IEEE SA, the Standards Committee, or the Working Group.

Comments on standards

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

membership affiliation with IEEE or IEEE SA. However, IEEE does not provide interpretations,

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 evaluating comments or in revisions to an IEEE standard is welcome

to join the relevant IEEE working group. You can indicate interest in a working group using the Interests tab

in the Manage Profile & Interests area of the IEEE SA myProject system. An IEEE Account is needed to

access the application.
Comments on standards should be submitted using the Contact Us form.
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 constitute 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.

Data privacy

Users of IEEE Standards documents should evaluate the standards for considerations of data privacy and

data ownership in the context of assessing and using the standards in compliance with applicable laws and

regulations.
Copyrights

IEEE draft and approved standards are copyrighted by IEEE under US and international copyright laws.

They are made available by IEEE and are adopted for a wide variety of both public and private uses. These

Copyright © 2021 IEEE. All rights reserved.
---------------------- Page: 7 ----------------------
ISO/IEC/IEEE 8802-3:2021/FDAM 14:2022(E)

include both use, by reference, in laws and regulations, and use in private self-regulation, standardization,

and the promotion of engineering practices and methods. By making these documents available for use and

adoption by public authorities and private users, IEEE does not waive any rights in copyright to the

documents.
Photocopies

Subject to payment of the appropriate licensing fees, IEEE will grant users a limited, non-exclusive license

to photocopy portions of any individual standard for company or organizational internal use or individual,

non-commercial use only. To arrange for payment of licensing fees, please contact Copyright Clearance

Center, Customer Service, 222 Rosewood Drive, Danvers, MA 01923 USA; +1 978 750 8400;

classroom use can also be obtained through the Copyright Clearance Center.
Updating of IEEE Standards documents

Users of IEEE Standards documents should be aware that these documents may be superseded at any time

by the issuance of new editions or may be amended from time to time through the issuance of amendments,

corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the

document together with any amendments, corrigenda, or errata then in effect.

Every IEEE standard is subjected to review at least every 10 years. When a document is more than 10 years

old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of

some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that

they have the latest edition of any IEEE standard.

In order to determine whether a given document is the current edition and whether it has been amended

through the issuance of amendments, corrigenda, or errata, visit IEEE Xplore or contact IEEE. For more

information about the IEEE SA or IEEE's standards development process, visit the IEEE SA Website.

Errata

Errata, if any, for all IEEE standards can be accessed on the IEEE SA Website. Search for standard number

and year of approval to access the web page of the published standard. Errata links are located under the

Additional Resources Details section. Errata are also available in IEEE Xplore. Users are encouraged to

periodically check for errata.
Patents
IEEE Standards are developed in compliance with the IEEE SA Patent Policy.
IMPORTANT NOTICE

IEEE Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure

against interference with or from other devices or networks. IEEE Standards development activities consider

research and information presented to the standards development group in developing any safety

recommendations. Other information about safety practices, changes in technology or technology

implementation, or impact by peripheral systems also may be pertinent to safety considerations during

implementation of the standard. Implementers and users of IEEE Standards documents are responsible for

determining and complying with all appropriate safety, security, environmental, health, and interference

protection practices and all applicable laws and regulations.

Introduction

This introduction is not part of IEEE Std 802.3cp-2021, IEEE Standard for Ethernet—Amendment 14: Bidirectional

10 Gb/s, 25 Gb/s, and 50 Gb/s Optical Access PHYs.

IEEE Std 802.3™ was first published in 1985. Since the initial publication, many projects have added

functionality or provided maintenance updates to the specifications and text included in the standard. Each

IEEE 802.3 project/amendment is identified with a suffix (e.g., IEEE Std 802.3ba™-2010).

The half duplex Media Access Control (MAC) protocol specified in IEEE Std 802.3-1985 is Carrier Sense

Multiple Access with Collision Detection (CSMA/CD). This MAC protocol was key to the experimental

Ethernet developed at Xerox Palo Alto Research Center, which had a 2.94 Mb/s data rate. Ethernet at

10 Mb/s was jointly released as a public specification by Digital Equipment Corporation (DEC), Intel and

Xerox in 1980. Ethernet at 10 Mb/s was approved as an IEEE standard by the IEEE Standards Board in 1983

and subsequently published in 1985 as IEEE Std 802.3-1985. Since 1985, new media options, new speeds of

operation, and new capabilities have been added to IEEE Std 802.3. A full duplex MAC protocol was added

in 1997.

Some of the major additions to IEEE Std 802.3 are identified in the marketplace with their project number.

This is most common for projects adding higher speeds of operation or new protocols. For example,

IEEE Std 802.3u™ added 100 Mb/s operation (also called Fast Ethernet), IEEE Std 802.3z added

1000 Mb/s operation (also called Gigabit Ethernet), IEEE Std 802.3ae added 10 Gb/s operation (also called

10 Gigabit Ethernet), IEEE Std 802.3ah™ specified access network Ethernet (also called Ethernet in the

First Mile) and IEEE Std 802.3ba added 40 Gb/s operation (also called 40 Gigabit Ethernet) and 100 Gb/s

operation (also called 100 Gigabit Ethernet). These major additions are all now included in and are

superseded by IEEE Std 802.3-2018 and are not maintained as separate documents.

At the date of IEEE Std 802.3cp-2021 publication, IEEE Std 802.3 was composed of the following

documents:
IEEE Std 802.3-2018

Section One—Includes Clause 1 through Clause 20 and Annex A through Annex H and Annex 4A.

Section One includes the specifications for 10 Mb/s operation and the MAC, frame formats and service

interfaces used for all speeds of operation.

Section Two—Includes Clause 21 through Clause 33 and Annex 22A through Annex 33E. Section

Two includes management attributes for multiple protocols and speed of operation as well as

specifications for providing power over twisted pair cabling for multiple operational speeds. It also

includes general information on 100 Mb/s operation as well as most of the 100 Mb/s Physical Layer

specifications.

Section Three—Includes Clause 34 through Clause 43 and Annex 36A through Annex 43C. Section

Three includes general information on 1000 Mb/s operation as well as most of the 1000 Mb/s Physical

Layer specifications.

Section Four—Includes Clause 44 through Clause 55 and Annex 44A through Annex 55B. Section

Four includes general information on 10 Gb/s operation as well as most of the 10 Gb/s Physical Layer

specifications.

Section Five—Includes Clause 56 through Clause 77 and Annex 57A through Annex 76A. Clause 56

through Clause 67 and Clause 75 through Clause 77, as well as associated annexes, specify subscriber

access and other Physical Layers and sublayers for operation from 512 kb/s to 10 Gb/s, and defines

---------------------- Page: 12 ----------------------
ISO/IEC/IEEE 8802-3:2021/FDAM 14:2022(E)

services and protocol elements that enable the exchange of IEEE Std 802.3 format frames between

stations in a subscriber access network. Clause 68 specifies a 10 Gb/s Physical Layer specification.

Clause 69 through Clause 74 and associated annexes specify Ethernet operation over electrical
