When utilizing Ethernet Cables, we hear the word CAT5e Cable and CAT6 Cable, so what is the gap? These two cables are known as twisted pair copper cable, both of them have 8 individual insulated copper wires and both are normally terminated with the RJ-45 connector. What is the important deal?
The original Ethernet data standards used copper coaxial cable to transfer data around the early packet switched networks.
10Base5
10Base5 networks used fairly stiff 0.375 inch, 50 ohm impedance coaxial cable, and it was often characterised by its Creamy Yellow external insulated coating. It absolutely was often linked to the wall such as a Dado Rail and was often known as Thick Ethernet. It turned out made to pass Ethernet signals at 10 Mbps over a maximum distance of 500 metres, and this might be extended up to 2500 metres using 4 repeaters.
10Base2
10Base2 networks utilised 50 ohm impedance coaxial cable that’s much thinner and much more flexible than 10Base5, nevertheless the Ethernet signals were designed to be transmitted over this medium at 10 Mbps, albeit over the much shorter distance close to 185 metres, which may be extended up to 925 metres by building 4 repeaters. Both 10Base5 and 10Base2 standards have grown to be largely obsolete and twisted pair cable is currently the normal wired network medium.
Twisted Pair Ethernet Cable
10BaseT was developed during the early 1980s and it mainly used Category 3 cable for transmissions around 10 Mbs over distances around 100 metres. Ethernet standards evolved to include faster data rate transmission and the 10BaseTx 100 Mbps and 1000Baset 1000 Mbps standards were introduced. Cat3 cable had not been longer had sufficient bandwidth reaction to handle these faster technologies therefore, the Cat5 and Cat5e cable standards were introduced which allowed data speeds at up to 100 Mbps and 1000 Mbps respectively. The initial Cat5 standard was for the 100BaseTx transmissions but was quickly superseded by Cat5e as the 1000BaseT standard became commonplace.
So what is the difference between CAT5e and CAT6 Cable? Well the cables are constructed in a similar way with 4 copper pairs, making 8 wires as a whole. Each set of two wires are colour coded and twisted around the other to help reduce Crosstalk. The Cat5e cable is rated up to 100Mhz and supports approximately 1 Gigabit Ethernet, as the Cat6 cable is rated up to 250Mhz and may support 10 Gigabit Ethernet signals.
Cat6 Ethernet Cable has over 2 twists per centimetre whereas Cat5e Ethernet Cable has only 1.5 to 2 twists per centimetre. As a result Cat6 Cable better protects against Crosstalk. Another difference would be that the sheath thickness is additionally greater low-priced Cat6 with Cat5e. A number of the Category 6 cables actually have a Nylon Spine and also the mixture of this spine and also the thicker sheath protect against Near End Crosstalk (NEXT) and Alien Crosstalk (AXT), which may increase because frequency increases.
Most Ethernet Cables in use are UTP (Unshielded Twisted Pair), because these include the cables recommended to use between add-ons including computers and also the wall socket. STP (Shielded Twisted Pair) Cables are suggested to be utilized for outdoor installations and for cable runs inside internal walls.
Stranded cables tend to be more flexible and therefore are more often used for computer to wall socket and for general home network use, but often businesses usually choose to solid cables in terms of the wiring inside walls and wiring ducts because superior strength that has been enhanced network performance.
To sum up, Category 5 enhanced cables are sufficient for most applications for accelerates to at least one Gigabit per second, however if you anticipate the application of 10 Gbps Ethernet down the road then Category 6 cable will future proof your investment. Also Category 6 cable, even with the 1 Gbps speeds will offer enhanced protection against errors.
