TIA/EIA 568a and 568b Wiring Color Codes

TIA/EIA-568-B.1-2001 is likely the most commonly used and talked about feature of the specification created in 1988. 568-a is the definition of pin assignments for the the pairs within Category 3 (CAT3), Category 5 (CAT5) and Category 6 (CAT6) unshielded twisted-pair (UTP) cables (eight conductor, 100-ohm balanced twisted pair cabling). The Pin/Pair assignments were named T568A and T568b, both of which define the pinout or specific order the UTP pairs need to be terminated within 8P8C (Eight Position, Eight Conductor) modular connecters, also known as RJ45 connectors.

Networx™ Cat5e RJ45 Modular Connector - 100 Pack Networx™ Cat5e RJ45 Modular Connector - 100 Pack

Networx™ CAT5e Modular Connectors are perfect for terminating all of your custom built, high-speed CAT5e patch cables. Manufactured with a high quality poly-carbonate body and receiving a UL 94V-2 flame rating, these CAT5e modular connectors are able to withstand heavy use and temperatures up to 125 degrees Celsius. Contacts are coated with 50 micro-inch of gold ensure that your data will be flowing without any constraints. Staggered connectors help maintain data integrity and cut down on cross-talk by using a One Up, One Down style that keeps the conductors separate and maintains the recommended twist throughout the connector.
Cat 5 e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. It was formally defined in 2001 as the TIA/EIA-568-B standard, which no longer recognizes the original Cat 5 specification. Although 1000BASE-T was designed for use with Cat 6 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BASE-T ethernet networks.
