Standards of Network Wiring
There are two wiring standards for network cabling. T568A and T568B are the two standards for the RJ-45 or 8-position modular connector, permitted under the TIA/EIA-568-A wiring standards document. The only difference between T568A and T568B (also known as Weco, AT&T 258A) is that the orange and green wire pairs (pairs two and three) are interchanged. How to decide which wiring pattern to use:
One bonus is that most networking equipment presently on the market have wiring diagrams for either T568A or T568B. Since the difference is only the switching of two pairs of wires, it is easy enough for manufacturers to print both standards on their hardware. For example, a patch panel that is labeled for T568A/T568B will usually have the color-coded wiring diagrams above and below the actual punchdown. One will typically be labeled T568A and the other T568B. This type of hardware is preferred by installers due to its flexibility. Call For More Info @ 813-901-9725 |
