When using Ethernet Cables, we hear the term Cat5e Cable and Cat6 Cable, so what is the difference? Both of these cables are referred to as twisted pair copper cable, both of them have 8 personel insulated copper wires and both are regularly finished with an Rj-45 connector. So what's the big deal?
The traditional Ethernet data standards used copper coaxial cable to replacement data on the early packet switched networks.
Server Rails
10Base5
10Base5 networks used fairly stiff 0.375 inch, 50 ohm impedance coaxial cable, and was often characterised by its Creamy Yellow external insulated coating. It was often attached to the wall similar to a Dado Rail and was often known as Thick Ethernet. It was designed to pass Ethernet signals at 10 Mbps over a maximum length of 500 metres, and this could be extended up to 2500 metres using 4 repeaters.
10Base2
10Base2 networks utilised 50 ohm impedance coaxial cable that was much thinner and more flexible than 10Base5, but the Ethernet signals were still designed to be transmitted over this medium at 10 Mbps, albeit over a much shorter length of colse to 185 metres, which could be extended up to 925 metres with the expanding of 4 repeaters. Both the 10Base5 and 10Base2 standards have come to be largely obsolete and twisted pair cable is now the coarse wired network medium.
Twisted Pair Ethernet Cable
10BaseT was advanced in the early 1980s and it in general used kind 3 cable for transmissions up to 10 Mbs over distances up to 100 metres. Ethernet standards evolved to comprise faster data rate transmission and the 10BaseTx 100 Mbps and 1000Baset 1000 Mbps standards were introduced. Cat3 cable was no longer had adequate bandwidth response to deal with these faster technologies and so the Cat5 and Cat5e cable standards were introduced which allowed data speeds at up to 100 Mbps and 1000 Mbps respectively. The traditional Cat5 accepted was fine for the 100BaseTx transmissions but was fast superseded by Cat5e as the 1000BaseT accepted became commonplace.
So what is the difference in the middle of Cat5e and Cat6 Cable? Well the cables are constructed in a similar manner with 4 copper pairs, development 8 wires in total. Each pair of wires are colour coded and twisted colse to each other to help sacrifice Crosstalk. The Cat5e cable is rated up to 100Mhz and supports up to 1 Gigabit Ethernet, whilst the Cat6 cable is rated up to 250Mhz and can keep 10 Gigabit Ethernet signals.
Cat6 Ethernet Cable has over 2 twists per centimetre whereas Cat5e Ethernet Cable only has 1.5 to 2 twists per centimetre. The follow is that Cat6 Cable better protects against Crosstalk. Someone else difference is that the sheath thickness is also greater when comparing Cat6 with Cat5e. Some of the kind 6 cables literally have a Nylon Spine and the blend of this spine and the thicker sheath safe against Near End Crosstalk (Next) and Alien Crosstalk (Axt), which can growth as the frequency increases.
Most Ethernet Cables in use are Utp (Unshielded Twisted Pair), as these are the cables recommended to be used in the middle of your peripheral devices such as computers and the wall socket. Stp (Shielded Twisted Pair) Cables are recommended to be used for outdoor installations and also for cable runs inside internal walls.
Stranded cables are more flexible and are more often used for computer to wall socket and for normal home network use, but often businesses regularly prefer the solid cables when it comes to the wiring inside walls and wiring ducts due to its classic force and enhanced network performance.
In summary, kind 5 enhanced cables are adequate for most applications for speeds up to 1 Gigabit per second, but if you anticipate the use of 10 Gbps Ethernet in the time to come then kind 6 cable will time to come proof your investment. Also kind 6 cable, even at the 1 Gbps speeds will give enhanced security against errors.
