Which connector is used to terminate Twisted Pair Cables?

Twisted pair cables, commonly used in networking and telecommunications, are terminated with RJ-45 connectors. These connectors are designed specifically for Ethernet and network cabling, allowing the transmission of data over the cables effectively. The structure of an RJ-45 connector includes eight pins that correspond to the individual wires within the twisted pair cable, enabling them to transfer signals and data at high speeds.

RJ-11 connectors, while similar in appearance, are typically used for telephone connections and utilize only four or six pins, which makes them unsuitable for the data transmission needs of networks utilizing twisted pair cables. USB connectors are designed for peripheral connections, such as keyboards, mice, and storage devices, which do not relate to twisted pair cable applications. SC connectors are used in fiber optic cabling, not in twisted pair cabling, as they are designed for optical signals rather than electrical signals. Therefore, the RJ-45 connector is the correct choice for terminating twisted pair cables, specifically in Ethernet networks.
