An Ethernet cable is a type of network cable used to connect devices on a wired network. It's a physical, tangible connection that transmits data between devices like computers, routers, switches, and other network-enabled devices.
Inside an Ethernet cable are typically eight copper wires twisted together in pairs. This twisting helps reduce electromagnetic interference, ensuring a stable and reliable data transmission. The cable is terminated with an RJ45 connector, a standard 8-position modular connector.
Types of Ethernet Cables
Ethernet cables come in various categories, each with different specifications for speed, shielding, and performance:
Ethernet cables are the backbone of modern wired networks, enabling high-speed data transmission between devices. The most common types are Cat5e, Cat6, and Cat6a, each offering different performance characteristics and suitable for various applications.
Key Differences:
Feature | Cat5e | Cat6 | Cat6a |
---|---|---|---|
Bandwidth | 100 MHz | 250 MHz | 500 MHz |
Maximum Speed | 1 Gbps | 10 Gbps | 10 Gbps |
Distance (10 Gbps) | N/A | 55 meters | 100 meters |
Distance (1 Gbps) | 100 meters | 100 meters | 100 meters |
Cost | Most affordable | More expensive than Cat5e | Most expensive |
