Abstract: This amendment to IEEE Std 802.3-2002 as amended by IEEE Std 802.3ae-2002, IEEE
Std 802.3af-2003, IEEE Std 802.3aj-2003, and IEEE Std 802.3ak-2004 combines a minimal set of
extensions to the IEEE 802.3 Media Access Control (MAC) and MAC Control sublayers with a
family of Physical (PHY) Layers. These Physical Layers include optical fiber and voice grade copper
cable Physical Medium Dependent sublayers (PMDs) for point-to-point connections in subscriber
access networks. This amendment also introduces the concept of Ethernet Passive Optical
Networks (EPONs), in which a point to multi-point (P2MP) network topology is implemented with
passive optical splitters, along with optical fiber PMDs that support this topology. In addition, a
mechanism for network Operations, Administration and Maintenance (OAM) is included to facilitate
network operation and troubleshooting. To support these innovations, options for unidirectional
transmission of frames are provided for 100BASE-X, 1000BASE-X, 10GBASE-R, 10GBASE-W,
and 10GBASE-X.

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. Every IEEE Standard is subjected to review at least every five years for
revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, 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 publishing and making this document available, the IEEE is not suggesting or rendering professional or other services

competent professional in determining the exercise of reasonable care in any given circumstances.
Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific
applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare
appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any
interpretation has also received 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 interpretation requests except
in those cases where the matter has previously received formal consideration. 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, explanation, or interpretation of the IEEE.
Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with
IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate
supporting comments. Comments on standards and requests for interpretations should be addressed to:

Introduction
(This introduction is not part of IEEE Std 802.3ah-2004, IEEE Standard for Information technology—
Telecommunications and information exchange between systems—Local and metropolitan area networks—
Specific requirements— CSMA/CD Access Method and Physical Layer Specifications Amendment: Media
Access Control Parameters, Physical Layers, and Management Parameters for Subscriber Access Networks).
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 802.3ae). A historical listing of all
projects that have added to or modified IEEE Std 802.3 follows as a part of this introductory material. The
listing is in chronological order of project initiation and for each project describes: subject, clauses added (if
any), approval dates, and committee officers.
The media access control (MAC) protocol specified in IEEE Std 802.3 is Carrier Sense Multiple Access
with Collision Detection (CSMA/CD). This MAC protocol was included in the experimental Ethernet
developed at Xerox Palo Alto Research Center. While the experimental Ethernet had a 2.94 Mb/s data rate,
IEEE Std 802.3-1985 specified operation at 10 Mb/s. Since 1985 new media options, new speeds of
operation, and new protocol capabilities have been added to IEEE Std 802.3.
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 802.3x™ specified full duplex
operation and a flow control protocol, IEEE Std 802.3z™ added 1000 Mb/s operation (also called Gigabit
Ethernet) and IEEE Std 802.3ad™ specified link aggregation. These major additions are all now included in
IEEE Std 802.3-2002 and are not available as separate documents.
Recent additions such as IEEE Std 802.3ae (also called 10 Gigabit Ethernet) and IEEE Std 802.3af (also called
Power over Ethernet) are currently published as separate documents. These recent amendments are part of
IEEE Std 802.3 and they are dependent on and reference information published in IEEE Std 802.3-2002.
At the date of IEEE Std 802.3ah publication, IEEE Std 802.3 is comprised of the following documents:
IEEE Std 802.3-2002
Section One—Includes Clause 1 through Clause 20 and Annexes A through H. 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 32 and Annexes 22A through 32A. Section Two
includes the specifications for 100 Mb/s operation and management attributes for multiple
protocols and operational speeds.
Section Three—Includes Clause 34 through Clause 43 and Annexes 36A through 43C. Section
Three includes the specifications for 1000 Mb/s operation.
IEEE Std 802.3ae-2002
Includes changes to IEEE Std 802.3-2002, and adds Clause 44 through Clause 53 and Annexes 44A
through 50A. This amendment includes specifications for 10 Gb/s operation.
IEEE Std 802.3af-2003
Includes changes to IEEE Std 802.3-2002, and adds Clause 33 and Annexes 33A through 33E. This
amendment includes specifications for the provision of power over 10BASE-T, 100BASE-TX, and
1000BASE-T cabling.

IEEE Std 802.3ak-2004
Includes changes to IEEE Std 802.3-2002, and IEEE Std 802.3ae-2002, and adds Clause 54. This
amendment adds 10GBASE-CX4 specifications for 10 Gb/s operation over balanced shielded
cabling.
IEEE Std 802.3ah-2004
Includes changes to IEEE Std 802.3-2002, IEEE Std 802.3ae-2002, and IEEE Std 802.3af-2003,
and adds Clause 56 through Clause 67 and Annex 58A through Annex 67A. This amendment
defines services and protocol elements that permit the exchange of IEEE Std 802.3 format frames
between stations in a subscriber access network.
IEEE Std 802.3 will continue to evolve. Revisions are anticipated to the above standards within the next few
years to integrate approved changes into IEEE Std 802.3, to clarify existing material, to correct possible
errors, and to incorporate new related material.
Conformance test methodology
An additional standard, IEEE Std 1802.3™-2001, provides conformance test information for 10BASE-T.
IEEE Std 802.3ah-2004
IEEE Std 802.3ah-2004, Ethernet in the First Mile is an amendment to IEEE Std 802.3. The standard includes
changes to IEEE Std 802.3, and these changes are marked in comparison to the last published standard. In
some cases, text included in IEEE Std 802.3-2002 has been modified by IEEE Std 802.3ae-2002, IEEE Std
802.3af-2003, then IEEE Std 802.3aj-2003 and again by IEEE Std 802.3ah-2004.
This document defines services and protocol elements that permit the exchange IEEE Std 802.3 format
frames between stations in a subscriber access network.
