2. 光纤跳线：光纤跳线是用于连接光纤设备的线缆，常见的类型有单模光纤跳线和多模光纤跳线。 3. 模块和适配器：模块和适配器用于将不同类型的网络接口进行转换和连接，如SFP模块和光模块适配器等。 三、认识与使用 要正确使用各类网络接口及连接配件，需要了解它们的特性和应用场景。例如，在局域网中，我们需要使用RJ45接口和网线来连接计算机和网络设备；在长距离网络连接中，我们需要使用光纤接口和光纤跳线来保证数据的高速传输；在连接外部设备时，我们需要使用USB接口和相关配件。 四、英文翻译 Various Types of Network Interfaces and Connection Accessories Network interface is an important part of connecting network devices and computers, which is responsible for data transmission and exchange. According to different application scenarios and transmission speed requirements, network interfaces are mainly divided into the following categories: 1. Ethernet interface: The most common type of network interface, it is widely used in both local and wide area networks. Common Ethernet interfaces include RJ45 interfaces and SFP interfaces. 2. Fiber optic interface: It is used for high-speed data transmission and is mainly applied in long-distance network connections. Common fiber optic interface types include SC, LC, ST, etc. 3. USB interface: In addition to data transmission, USB interfaces can also be used to connect external devices such as printers and cameras. Connection accessories are important components of network interfaces, which can effectively protect network interfaces and improve the stability and reliability of data transmission. Common connection accessories include:

1. Network cable: It is an important tool for connecting network devices and computers, with common types including twisted-pair cable and coaxial cable. 2. Fiber optic patch cable: It is a cable used to connect fiber optic devices, with common types including single-mode and multi-mode fiber optic patch cables. 3. Modules and adapters: They are used to convert and connect different types of network interfaces, such as SFP modules and optical module adapters. To correctly use various network interfaces and connection accessories, it is necessary to understand their characteristics and application scenarios. For example, in a local area network, we need to use RJ45 interfaces and network cables to connect computers and network devices; in long-distance network connections, we need to use fiber optic interfaces and fiber optic patch cables to ensure high-speed data transmission; when connecting external devices, we need to use USB interfaces and related accessories.
