The Category 6 Consortium is an emerging working group whose mission is to create market and industry awareness - as well as demand - for cabling systems and components based on TIA's new category 6 cabling standard. To learn more about the Category 6 Consortium and to participate, please contact TIA at (703) 907-7723 or email jmead@tiaonline.org.

What is the difference between enhanced category 5e cable rated for 400 MHz and category 6 cable rated for 250 MHz? Category 5e requirements are specified up to 100 MHz. Cables can be tested up to any frequency that is supported by the test equipment, but such measurements are meaningless without the context of applications and cabling standards. The Category 6 standard sets minimum requirements up to 250 MHz for cables, connecting hardware, patch cords, channels and permanent links, and therefore guarantees reasonable performance that can be utilized by applications. 2. Why did all category 6 cable used to have a spline, and now is offered without one? Some Category 6 cable designs have a spline to increase the separation between pairs and also to maintain the pair geometry. This additional separation improves NEXT performance and allows Category 6 compliance to be achieved. With advances in technology, manufacturers have found other ways of .
