Описание (английский):

This document defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at selected speeds of operation; and uses a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) provide an architectural and optional implementation interface to selected Physical Layer entities (PHY). The Physical Layer encodes frames for transmission and decodes received frames with the modulation specified for the speed of operation, transmission medium and supported link length. Other specified capabilities include: control and management protocols, and the provision of power over selected twisted pair PHY types.

Abstract

Overview

ISO/IEC/IEEE 8802-3:2021 - "Standard for Ethernet" - is the international specification for Ethernet local, access and metropolitan area networks (LAN/MAN). Published as the third edition, it defines Ethernet operation across selected speeds from 1 Mb/s to 400 Gb/s, using a common Media Access Control (MAC) and management information base (MIB). The standard covers both shared-medium (half‑duplex) and full‑duplex operation, physical interfaces, management and control protocols, and power delivery over selected twisted‑pair PHY types.

Key topics and technical requirements

MAC specification & CSMA/CD: Defines the common MAC behavior including Carrier Sense Multiple Access with Collision Detection (CSMA/CD) for shared media and full duplex modes.
Speed-specific Media Independent Interfaces (MIIs): Architectural interfaces that allow MAC layers to interoperate with a variety of Physical Layer (PHY) devices.
Physical Layer (PHY) & PMD/PMA/PCS: Specifies how frames are encoded/decoded for transmission over coaxial cable, twisted pair, fiber optics, or electrical backplanes; modulation and link-length considerations are speed- and medium-dependent.
Management & MIB: Standard management information base for network monitoring and control.
Power over data lines: Provision for Power over Ethernet (PoE) / Power over Data Lines on selected twisted‑pair PHY types.
Repeaters and multi‑segment operation: System guidance for multisegment networks including repeaters (defined up to 1000 Mb/s).
Supported technologies & keywords: Covers a wide set of Ethernet variants including Fast Ethernet, Gigabit Ethernet, 2.5/5/10/25/40/100/200/400 Gigabit Ethernet, Energy Efficient Ethernet, EPON/EPoC and backplane Ethernet.

Practical applications and who uses this standard

Network equipment manufacturers designing switches, NICs, PHY transceivers and backplane interfaces
Cable and optical transceiver vendors implementing PMD/PMA/PCS layers
Data center, campus and carrier‑grade network architects planning LAN and metropolitan deployments
System integrators, test labs and compliance teams validating interoperability, performance and PoE implementations
Standards bodies and procurement teams referencing IEEE 802.3 / ISO/IEC requirements for regulatory or contract compliance

Related standards

IEEE 802.3 family (electrical and optical PHYs, amendments)
ISO/IEC JTC 1 SC 6 (telecommunications and information exchange between systems)
Prior edition: ISO/IEC/IEEE 8802-3:2017 (superseded by the 2021 third edition)

ISO/IEC/IEEE 8802-3:2021 is essential reading for anyone implementing or certifying Ethernet products and networks-especially where multi‑speed interoperability, physical‑layer selection, management, and PoE compatibility are required.
