Category 5 cable (Cat 5) is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet.
The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet). Cat 5 is also used to carry other signals such as telephony and video.
The cables come in various lengths, up to 10 m for machine fabricated, and up to 100m for custom made. There are a variety of colours available for 10m and shorter cables. Any cables over this length will be grey.
