What is network cable?

Network cable connection refers to the use of network cables (also known as network cables, Ethernet cables or data cables) to connect computers, network devices or other devices to the network or the Internet.
A network cable is a type of cable used for transmitting data signals in computer networks. It is usually composed of multiple insulated wires and insulation layers, with a protective layer covering the outside to provide protection against electromagnetic interference and physical damage. Common network cables use copper cores and are connected using RJ-45 plugs.
Network cables are typically used to connect data transmission between computers, routers, switches, modems, and other network devices. By connecting to the network, devices can conduct interconnection and data exchange to realize file sharing, Internet access, online games, video streaming media and other network services.
Different types of network cables can support different transmission rates and distances. Common types of network cables include:
Cat5e (Category 5e): Supports transmission rates up to 1 Gbps (gigabits per second), commonly used in home networks and small office networks.
Cat6 (Category 6): Supports higher transmission rates, reaching 10 Gbps, while having better resistance to electromagnetic interference.
Cat6a (Category 6a): Provides higher performance and anti-interference capabilities, supports transmission rates up to 10 Gbps, and is suitable for longer transmission distances.
Fiber Optic Cable: Using fiber optic as the transmission medium, it has higher transmission speed and anti-interference ability, suitable for long-distance and high-speed network connections.
The quality and correct installation of network cable connections are crucial for network performance. Ensuring the correct selection and installation of appropriate types and qualities of network cables, as well as maintaining good connections and cable routing, can ensure the stability and performance of network connections.
