Which of the following are standards-compliant wiring schemes for 8P8C modular connectors?

The answer encompasses T568A and T568B, which are established wiring schemes for 8P8C modular connectors, commonly used in networking applications like Ethernet cabling. Both T568A and T568B are defined by the Telecommunications Industry Association (TIA) and are included in the TIA/EIA-568 standards for structured cabling.

T568A offers a wiring configuration that promotes compatibility with certain legacy systems, making it a preferred choice for some installations based on historical practices. On the other hand, T568B is often used in commercial applications and gained popularity due to its widespread adoption in the United States.

Using either T568A or T568B ensures proper communication over the network and maintains compliance with industry standards. Employing these wiring schemes helps prevent wiring errors, such as crossed pairs, which could lead to connectivity issues and diminished network performance.

In contrast, the other choices may not refer to standards that are widely recognized or utilized in the industry for 8P8C connectors. Therefore, T568A and T568B are the appropriate options that ensure adherence to established wiring standards, enabling reliable and efficient communication in networking systems.
