IEEE 802.3是一个工作组，也表示此工作组制定的一系列IEEE标准，这些标准都是物理层和数据链路层（MAC）的有线以太网标准（802.11是WiFi）。一般情况下，以太网就是一个局域网络，带有广域网的一些功能应用。物理连接存在与节点之前，或者节点与网络设备之间 ...

May 18, 2017 · IEEE Standard for Ethernet Amendment: Cabling Restrictions for Single Pair Power over Ethernet (SPoE) The scope of the project is the specification of requirements and restrictions for supporting the IEEE 802.3 ‘plug-and-play' interoperability model for Single-Pair Power over Ethernet (SPoE) due to current carrying capacity limitations in ...

Aug 31, 2018 · Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 400 Gb/s using 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 …

Mar 22, 2025 · 千兆以太网（Gigabit Ethernet） 是 IEEE 802.3z 和 IEEE 802.3ab 标准定义的以太网技术，目标是在传统以太网基础上将传输速率提升至 1 Gbps（1000 Mbps） ，同时兼容百兆/十兆设备，满足高速数据传输需求。

Mar 22, 2023 · (Ethernet /ˈiːθərnɛt/ is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since been refined to support higher bit rates and longer link distances.)
