Categorized cable, also known as Ethernet or LAN cable, is the most standard cable when building a structured cable infrastructure to boost voice and data network performance for your small or large business.
Consisting of four Unshielded Twisted Pair (UTP) copper cables, ethernet cable is divided into subcategories depending on their performance, such as Cat5, Cat5e, Cat6a/e.
The performance of Cat (categorized) cabling is determined by its Bandwidth and rate of transfer speed, where signal is degraded over long distances, for this reason the maximum length of cable is set to 100 meters. Because Cat cable has the same twisted wire design, cat cable can be used in conjunction with other Cat cable allowing for backwards compatibility, where the lowest performance cable is the determining factor.
Structured cabling is governed by a set of telecommunication standards TIA/EIA-568 A and B which helps insure best practices for design and installation for voice, video and data networks.

Category 5 cable also called Cat5 is a cable typically used for home or small businesses. At a frequency of 100 MHz, Cat 5 transfers data between 10 to 100 Mbps and is suitable for most basic internet, phone and video structured cable designs while also being the most cost efficient. This cable is no longer in use.
Cat5e or Enhanced Category 5 is the upgraded version of Cat5. Both Cat5 and Cat5e transmits at a bandwidth of 100 MHz, but whereas Cat5 can transfer data at speeds up to 100 Mbps, Cat5e can transmit at 1000 Mbps.
Cat6 is the step up from Cat5e. It has a bandwidth of 250 MHz and data speeds of 1000 Mbps, but those speeds can be improved to 10 Gbps if length is reduced to 55 meters from 100 meters. While the main difference between Cat6 and Cat5e is the bandwidth, Cat6 has a lower crosstalk (signal interference) and less signal loss using a tighter cable twist.
Augmented Category 6 or Cat6a is the upgraded version of Cat6 and is capable of transfer speeds of 10 Gbps at 100 meters, unlike its predecessor Cat6. A bigger advancement is that Cat 6a has double the bandwidth from 250 to 500 MHZ. Also, Cat6a commonly comes with extra fortification using Shielded Twisted Pair (STP) that has better protection against crosstalk and other interference.
After Cat6a comes Cat7. Cat7 has a higher bandwidth at 600 MHz and a data transfer rate of 10 Gbps. It differs from other ethernet cables in that it has a thicker layer of shielding giving it more durability while providing even less signal interference. Cat7 also carries a longer life cycle but comes with a steeper price.
| CATEGORY | BANDWIDTH | DATA TRANSFER RATE |
| Cat 5 | 100MHz | 10-100 Mb/s |
| Cat 5e | 100MHz | 1000 Mb/s |
| Cat 6 | 250MHz | 1000 Mb/s |
| Cat 6a | 500MHz | 10 Gb/s |
| Cat 7 | 600MHz | 10 Gb/s |
