Understanding Ethernet Cables – Cat 5e and Cat6a Network Cables
Standards organizations are continually working with cable manufacturers to improve the capability of 4 pairs of 22-24 gauge copper wiring. For this reason we now have augmented cat6a, or 10Gigabit Ethernet data cable. The prior revision towards the 568-B cabling standard made provision for cat5e cable, that was able to deliver 250 Megahertz performance, which can give speeds of up to 1000 Megabits, giving rise to Gigabit Ethernet networks. Cat6 and augmented Cat6 data cabling, is capable of doing delivering data speeds of up to 10 Gigabits. This is a tenfold rise in speed over Category 5e cable.

Once the Category 5 standard was introduced, data rates were much slower than they are today. Thus performance degrading characteristics from the underlying copper cabling, like the many forms of crosstalk, delay, and attenuation, weren't as tightly controlled because they are today. In order to pass Category 6 standards compliance testing, cabling must show reduced overall crosstalk, attenuation, and delay than cables created to the previous standards. Category 6 data cabling is certified to become capable of delivering 10 Gigabit Ethernet performance standards only up to 55 metres in length for the permanent link. When Augmented Category 6 data cabling can be used, that permanent link length is increased to 100 metres.
Cable Testing Versus Cable Certification

There's two basic ways to test an installed cable. The first, and easiest, is called wiremapping. This verifies the cable is terminated the same way on ends. A cable map will also show the individual performing the test which cables are improperly terminated. The second approach to cable testing can be further divided into two separate methods. Each method entail putting the installed cable via a number of tests that test for that many forms of crosstalk, delay, and attenuation. The very first method, cable testing, verifies the tested cable performs up to the necessary standard. Cable certification takes this one step further and offers a printout that shows each cable's physical label, where it's installed, what network is serves, and also the outcomes of the various standards tests the tester tested for, for example crosstalk, power sum near end crosstalk, delay, attenuation, and delay skew.
How to Determine What Kind of Cable to make use of
Augmented Cat6a or 10 Gigabit Ethernet is the newest and therefore priciest copper cabling available for use on phone and data networks. Your house network might not have to take advantage of the speeds this cable type is capable of delivering. Actually, most home networking equipment now available won't provide the speeds that Augmented Cat6a or 10 Gigabit Ethernet cable is capable of doing delivering. Home internet speeds can't take care of the 1000 Megabit Ethernet speeds that cat5e is capable of doing, let alone the ten Gigabit speeds that augment Cat6a cable can deliver. However, this shortcoming will quickly be remedied and also the market will have a wide selection of equipment which will make the most of 10 Gigabit Ethernet speeds. Internet access speeds, using the advent of fiber towards the home, will even soon be able to keep up with augmented Cat6a cable. Using this cable type will make sure that the network cabling stays current for an extended period of time.
