Cat 5e is a type of twisted pair cable used for networking and telecommunications. It supports data transmission speeds of up to 1 Gbps (Gigabit per second) and can handle frequencies up to 100 MHz. This makes it suitable for most home and office networking needs, including internet connections and local area networks (LANs). The "e" in Cat 5e stands for "enhanced," indicating improvements over the earlier Cat 5 standard. These enhancements reduce crosstalk and interference, allowing for better performance over longer distances. Cat 5e cables are commonly used in Ethernet networks and are backward compatible with older standards.
