LAN cable patch cord, commonly known as an Ethernet patch cable, is a short, flexible cable used to connect devices within a local area network (LAN). Typically featuring RJ45 connectors at both ends, these cables are ideal for establishing quick and reliable connections between computers, routers, and switches. Their compact design and flexibility make them suitable for use in tight spaces, such as behind desks or within server racks, facilitating efficient cable management. Ethernet patch cables come in various categories, including Cat5e, Cat6, and Cat6a, each offering different performance levels in terms of speed and bandwidth. They are essential for ensuring stable and high-speed data transmission in networking environments.
