EIATIA Standards- EIA/TIA Wiring Standards- EIATIA 568A-EIA/TIA 568s

American Tech Supply has offered the following information to assist you in making you CAT 5e EIA/TIA wiring easy and stress -free. When you have completed your education- we hope you come back and purchase your Cat 5e and CAT 6 cables from us. We stock a complete array of CAT 6 patch cords and CAT 6 patch cables and includes our molded- booted CAT 6 Patch cords and patch cables. Our CAT 6 patch cords accommodate both T568A and T568B wiring applications, and are offered in several colors for easy circuit identification. High-quality CAT 6 patch cords are a critical, and sometimes overlooked, part of any high-performance cabling system. The only real way to guarantee modular CAT 6 patch cord performance is to test every CAT 6 patch cord across all pairs combinations, in both directions, after assembly. 100% factory transmission testing is critical to ensure the quality of the assembly process.

If we apply the 568A color code and show all eight wires, our pin-out looks like this:

Note that pins 4, 5, 7, and 8 and the blue and brown pairs are not used in either standard. Quite contrary to what you may read elsewhere, these pins and wires are not used or required to implement 100BASE-TX duplexing--they are just plain wasted.

However, the actual cables are not physically that simple. In the diagrams, the orange pair of wires are not adjacent. The blue pair is upside-down. The right ends match RJ-45 jacks and the left ends do not. If, for example, we invert the left side of the 568A "straight"-thru cable to match a 568A jack--put one 180° twist in the entire cable from end-to-end--and twist together and rearrange the appropriate pairs, we get the following can-of-worms:

This further emphasizes, I hope, the importance of the word "twist" in making network cables which will work. You cannot use an flat-untwisted telephone cable for a network cable. Furthermore, you must use a pair of twisted wires to connect a set of transmitter pins to their corresponding receiver pins. You cannot use a wire from one pair and another wire from a different pair.

Keeping the above principles in mind, we can simplify the diagram for a 568A straight-thru cable by untwisting the wires, except the 180° twist in the entire cable, and bending the ends upward. Likewise, if we exchange the green and orange pairs in the 568A diagram we will get a simplified diagram for a 568B straight-thru cable. If we cross the green and orange pairs in the 568A diagram we will arrive at a simplified diagram for a crossover cable. All three are shown below.

Molded CAT 6 Patch Cord Typical CAT 5e Booted Patch Cord

Our CAT 6Patch Cords use compliant stranded wire as specified by the latest published TIA guidelines to ensure adequate 'flex life’ and long term channel integrity. All of our CAT 6 patch cords have quality construction to maintain the quality of signal transmission at the cross-connect, which is critical to the performance of the entire cabling systemUse our patch cords for all types of networking, voice and even video applications (using baluns). They are approved for use with10Base-T, 100Base-T, 1000Base-T, and Token Ring-type 3. Each one is fully compliant with the Cat. 5e specification and exceeds the requirements of Ethernet IEEE 802.3ab and Token Ring UTP IEEE 205.5, (Category 5e and Category 6) and patch cord products including structured cabling products, Smart Home Cable, Smart Home Panels, and CAT 5-6 Testers.
