When using Ethernet Cables, we hear the definition of CAT5e Cable and CAT6 Cable, so what exactly is the gap? These two cables are called twisted pair copper cable, both of them have 8 individual insulated copper wires and both are normally terminated with an RJ-45 connector. What is the big deal?
The initial Ethernet data standards used copper coaxial cable to transfer data on 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 had been often coupled to the wall much like a Dado Rail and was often known as Thick Ethernet. It was made to pass Ethernet signals at 10 Mbps over a maximum distance of 500 metres, and this might be extended around 2500 metres using 4 repeaters.
10Base2
10Base2 networks utilised 50 ohm impedance coaxial cable that was much thinner and much more flexible than 10Base5, though the Ethernet signals remained as built to be transmitted over this medium at 10 Mbps, albeit over a much shorter distance of approximately 185 metres, that may be extended around 925 metres by building 4 repeaters. Both 10Base5 and 10Base2 standards are becoming largely obsolete and twisted pair cable is now the common wired network medium.
Twisted Pair Ethernet Cable
10BaseT was created in early 1980s plus it mainly used Category 3 cable for transmissions up to 10 Mbs over distances as much as 100 metres. Ethernet standards evolved to include faster data rate transmission and also the 10BaseTx 100 Mbps and 1000Baset 1000 Mbps standards were introduced. Cat3 cable had not been longer had sufficient bandwidth reaction to deal with 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 The first Cat5 standard was for the 100BaseTx transmissions but was quickly superseded by Cat5e as the 1000BaseT standard became commonplace.
So what is the main difference between CAT5e and CAT6 Cable? Well the cables are constructed in a similar way with 4 copper pairs, making 8 wires in whole. Each pair of wires are colour coded and twisted around the other person in lowering Crosstalk. The Cat5e cable is rated as much as 100Mhz and supports up to 1 Gigabit Ethernet, whilst the Cat6 cable is rated as much as 250Mhz which enable it to support 10 Gigabit Ethernet signals.
Cat6 Ethernet Cable has over 2 twists per centimetre whereas Cat5e Ethernet Cable merely has 1.5 to two twists per centimetre. Consequently Cat6 Cable better protects against Crosstalk. Another difference could be that the sheath thickness is also greater when you compare 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 control Near End Crosstalk (NEXT) and Alien Crosstalk (AXT), that may increase as the frequency increases.
Most Ethernet Cables being used are UTP (Unshielded Twisted Pair), since these include the cables recommended to use involving the peripheral devices including computers along with the wall socket. STP (Shielded Twisted Pair) Cables are suggested to be utilized for outdoor installations and also for cable runs inside internal walls.
Stranded cables tend to be more flexible and they are more frequently employed for computer to wall socket and for general home network use, but often businesses usually prefer the solid cables with regards to the wiring inside walls and wiring ducts because superior strength that has been enhanced network performance.
In summary, Category 5 enhanced cables are sufficient for the majority of applications for increases to 1 Gigabit per second, however if you simply anticipate the usage of 10 Gbps Ethernet in the foreseeable future then Category 6 cable will future proof forget about the. Also Category 6 cable, even in the 1 Gbps speeds will offer enhanced protection against errors.
