Twisted Pair cable is used in telecommunications for a variety of purposes. It has also evolved a great deal to improve performance. Twisted pair wiring standards are specified by the ANSI/EIA standard 568. This kind of cabling is probably best recognized for its role in modern Ethernet networks.
Categories
| Category[1] | Max Date Rate[1] | Purpose[1] |
|---|---|---|
| 1 | 1Mb/s | Voice communication |
| 2 | 4Mb/s | 4 Mbps token ring |
| 3 | 16Mb/s | 10BaseT Ethernet |
| 4 | 20Mb/s | 16 Mbps token ring |
| 5 | 100Mb/s (two pairs) | 100BaseT Ethernet |
| 5 | 1,000Mb/s (four pairs) | Gigabit Ethernet |
| 5e | 1,000Mb/s(two pairs) | Gigabit Ethernet |
| 6 | 1,000Mb/s (two pairs) | Gigabit Ethernet |
| 6a | 10,000 Mb/s | 10 gigabit |
| 7 | 10,000 Mb/s | 10 gigabit |
Networking
Modern networks typically use at least category 5e or above. Category 5 is also sometimes used, but offers slower service. To offer better service with upgrade capabilities, many networks are now composed of categories 6 or 6a.
When data is moving from one point to another through a network, the transfer can only be performed as quickly as the slowest choke point. For this reason, it is important to maintain consistent cabling throughout a network for optimal efficiency. A single category 5 cable in the wrong place will slow an entire 6a network to category 5 speed.
