COPPER CABLING:  TWISTED PAIR
Category-3 is characterized to 16 MHz to support applications up to 10 Mbps.  Typical applications are: voice, ISDN 4 Mbps Token Ring and 10base-T.

Category-5 is used in network applications such as 10Base-T, 100Base-T, Ethernet technology to 100 meters. They perform at high-data transfer rates. While Cat-5 may function at some level in a 1000Base-T switch, the performance is below standard during high-data transfer applications, which is what Cat-5e was specifically designed for.


Category-5E surpasses Category-5 channel specifications and provides more headroom than Category-5 in a 1000Base-T switch, or a Gigabit Ethernet. Typical applications range from 100Base-T to 1000Mbps systems.


Category-6 was designed for high-end network applications, having significant headroom and superior performance over Category-5E. Typical applications include: digital video, 100-Mbps TP-PMD and 155-Mbps ATM networks, 622-Mbps ATM, Gigabit Ethernet, and wideband Ethernet systems.
