Currently, there are two network cabling standards. It is essential to apply these standards for a proper installation of cables, safety from electrical accidents and a better system for network connection. The two standards for an RJ-45 modular connector are T568A and T568B which is permitted based on TIA/EIA-568-A standards for wiring.
The only dissimilarity between the two network cabling standards is the arrangement of green and orange wire pairs; they are completely interchanged. Deciding which network cabling standards to use is based on the following factors:
- Check which pattern is suitable for the job specification
- Always ask the customer which particular network cabling standard he or she prefers: T568A or T568B
- If you have purchased patch panels in advance, it is either T568A or T568B. Thus, the jacks should be patterned according to the patch panels.
- The new wiring must be compatible with the existing wiring to prevent incompatibility.
If the factors given above do not apply, you have the choice whether to use either of the two network cabling standards. Just keep in mind that the new connectors being installed should match the existing connectors. In general, T568B is generally used with business installations, whereas T568A is commonly seen on residential installations. In the event the installation is not specified, T568B are normally used.
Due to advances in technology, most of the equipment used to install networks today provides wiring patterns for both T568A and T568B. As mentioned above that the only difference is the interchanged orange and green wires, thus manufacturers discovered the way to establish the two existing network cabling standards on their hardware easily. This is possible through color coding to determine the standard. Overall, this kind of hardware is definitely preferred by many installers due to its flexibility.
