Cat 5 cable is a twisted pair cable for computer networks (usually 4 pair). This high-performance cable has a twisted pair conductors which are commonly used for data transmission. Available since 1995 Cat 5 cabling is usually used for ethernet networks running at 10/100Mbps over 100 metres. Over the years improvements have been made to this cable. The latest version is known as Cat 5e. Performance is slightly raised in the new standard for example, Cat 5e boasts less noise and crosstalk which in return delivers better data transmission.
The 6th generation of twisted pair ethernet cabling is also known as Cat 6, this cable can be found in homes and business networks. Launched in 2002 Cat 6 cabling has copper wires which are tightly wound up in comparison to Cat 5. In addition, this allows the cable to deliver a better performance with gigabit Ethernet transmissions at distances of 100M. Lastly, Cat 6 is backward compatible with Cat 5 & Cat 5e.
With a thicker shielding than Cat 5 and Cat 6 cabling, Cat 7 cables offer a better bandwidth and speed when it comes to data transmission. Unlike the previous cable Cat 7 can easily reach speeds of up to 100GBs/second in a range of 15 metres. 40GBs/second at 50 metres. Similar to Cat 6, Cat 7 is also backwards compatible with its predecessors.
