Which connector is used for Ethernet networking on twisted pair cables with 8 conductors?

• A. Ethernet (RJ11)
• B. Ethernet (RJ45)
• C. Ethernet (Shielded Twisted Pair)
• D. Ethernet (Unshielded Twisted Pair)

Answer: (B)

For Ethernet networking on twisted pair cables with 8 conductors, the connector is RJ45. This modular plug has eight positions and eight contacts, matching the eight wires inside Cat5e/Cat6 cables and the eight-port jack found on NICs, switches, and patch panels. RJ11 is a smaller telephone connector that typically carries two to four wires and isn’t designed for Ethernet, so it won’t provide the eight-wire interface. Shielded versus unshielded twisted pair refers to the cable construction, not the connector, and RJ45 works with both types. In modern Ethernet, especially with gigabit and faster speeds, all four pairs (eight conductors) are used, making RJ45 the standard choice for twisted-pair Ethernet.
