　　An Ethernet cable is a type of data transmission cable used to connect devices in a computer network. It is primarily used in local area networks (LANs) to link computers, routers, switches, and other network equipment, enabling digital communication. Essentially, it is a cable designed to transmit digital signals, and it can be either twisted-pair copper wire or fiber optic cable.

　　Common Types

　　1. Twisted-Pair Copper Cable

　　Categories:

　　Cat5 (Category 5): Supports up to 100 Mbps data transfer.

　　Cat5e (Enhanced): Supports Gigabit Ethernet (1 Gbps).

　　Cat6: Supports 10 Gbps over short distances with better interference resistance.

　　Cat6a / Cat7: Supports higher speeds and longer distances with improved shielding.

　　Structure: Consists of 8 copper wires arranged in 4 twisted pairs. Twisting reduces electromagnetic interference (EMI).

　　Applications: Home and office networks, connecting network devices.

　　2. Fiber Optic Cable

　　Characteristics: Transmits data using light signals, offering high bandwidth, long-distance transmission, and immunity to electromagnetic interference.

　　Applications: Data centers, telecom backbone networks, high-speed enterprise networks.

　　Appearance and Connectors

　　Copper Ethernet cables typically use RJ45 connectors.

　　Fiber optic cables commonly use SC, LC, or ST connectors.
