![]() ![]() Twisted pair became the basis for all Ethernet cables to eliminate interference between internal wires (XT), and external wires (AXT). ![]() He discovered that by twisting the cable every 3-4 utility poles, it reduced the interference and increased the range. Cable twisting was invented by Alexander Graham Bell in 1881 for use on telephone wires that were run along side power lines. So how does a physical cable eliminate interference and allow for faster speeds? It does it through wire twisting and isolation. The higher communication frequency eliminated alien crosstalk (AXT) which allows for longer range at 10 Gb/s. ![]() Every connection in your network needs to support the 1 Gb speed and in some cases, the connection will need to be told in software to use the available speed.Ĭategory 5 cable was revised, and mostly replaced with, Category 5 Enhanced ( Cat-5e) cable which did not change anything physically in the cable, but instead applied more stringent testing standards for crosstalk.Ĭategory 6 was revised with Augmented Category 6 ( Cat-6a) which provided testing for 500 Mhz communication (compared to Cat-6’s 250 Mhz). Just because you have Cat-6 cable, doesn’t mean you have 1 Gb network speeds either. Physically you can use Cat-5 cable for 1 Gb speeds, and I have personally used cable longer than 100 meters, but because the standard has not been tested for it, you’ll probably have mixed results. This does not mean your experiences have been the same. ![]()
