PHY

PHY（英语：Port Physical Layer），中文可称之为端口物理层，是一个对OSI模型物理层的共同简称。

PHY连接一个数据链路层的设备（MAC）到一个物理媒介，如光纤或铜缆线。典型的PHY包括PCS（Physical Coding Sublayer，物理编码子层）和PMD（Physical Media Dependent，物理介质相关子层）。PCS对被发送和接受的信息加码和解码，目的是使接收器更容易恢复信号。

PHY是一个操作OSI模型物理层的设备。一个以太网PHY是一个芯片，可以发送和接收以太网的数据帧（frame）。它通常缺乏NIC（网络接口控制器）芯片所提供的Wake-on-LAN或支持Boot ROM的先进功能。此外，不同于NIC，PHY没有自己的MAC地址。
