How do T568A and T568B systems primarily differ?

• A. The types of cables used
• B. The wiring configurations for terminating cables
• C. The color of the connectors
• D. The bandwidth specifications

Answer: (B)

The primary difference between T568A and T568B systems lies in the wiring configurations used for terminating cables. Both standards define how to arrange the individual wires within twisted-pair cabling, specifically for Category 5e, Category 6, and other similar types of cables. In T568A, the pinouts for the wiring are configured differently compared to T568B, which results in a different arrangement of the pairs in the RJ45 connectors. This can impact compatibility when connecting devices and ensures that the correct wiring scheme is followed to maintain performance and reduce cross-talk. While the other options may relate to cabling systems, they do not represent the fundamental difference between T568A and T568B. For instance, both standards utilize the same types of cables, the connectors themselves are often the same in terms of physical design, and the bandwidth specifications are not different between the two; both adhere to similar performance standards. The focus on the wiring configuration is key for ensuring reliable network communications.
