物理和虚拟网络接口
通过接口驱动把设备连接到网络，或以虚拟方式模拟网络接口的产品。
类别解释
Physical and virtual network interfaces
物理网络接口是通过接口驱动程序提供的应用程序编程接口（API）将设备直接连接到网络的数字要素产品，通常运行于数据链路层，并包含连接传输介质的硬件适配器及相应固件。虚拟网络接口则是通过模拟物理网络接口驱动程序 API 的接口，将设备直接或间接连接到网络的产品。本类别包括有线和无线网络接口卡、控制器及适配器，例如 Wi-Fi、以太网、IrDA、USB、蓝牙接口。
English
Physical network interfaces connect a device directly to a network through an API provided by the interface drivers, typically operating at the data link layer and including hardware adapters for transmission media with corresponding firmware. Virtual network interfaces connect a device directly or indirectly to a network through an interface emulating the physical network interface driver API. The category includes wired and wireless network interface cards, controllers and adapters such as Wi-Fi, Ethernet, IrDA, USB and Bluetooth interfaces.
CRA 附件三 I 类，技术描述见实施条例 (EU) 2025/2392 附件一第 1–19 项
Class I of Annex III to the CRA, with technical descriptions in Annex I, points 1–19, of Implementing Regulation (EU) 2025/2392
制造商可采用协调标准（或技术规范）证明符合性，据此完成内部合格评定；未适用协调标准时，须按模块 B+C 或模块 H 由公告机构参与评定。
Manufacturers may demonstrate conformity through harmonised standards or technical specifications and self-assess; where no harmonised standard is applied, Module B+C or Module H with a notified body applies.
重要产品 · I 类的主要义务
