How many pairs of wires do the 10BASE-T and 100BASE-T use?

Both 10BASE-T and 100BASE-T technologies utilize two pairs of twisted copper wires for communication. In these Ethernet standards, one pair is used for transmitting data while the other pair is used for receiving data. This approach allows for full-duplex communication, meaning data can be sent and received simultaneously, which significantly enhances network performance. Moreover, these standards employ Category 5 (Cat 5) or better cabling, which includes four pairs of wires, but only two of those pairs are actively used during transmission. Leveraging two pairs enables a more efficient use of the available wiring while supporting the respective bandwidths required for 10 Mbps and 100 Mbps speeds. This design was a key factor in the widespread adoption of these Ethernet standards in local area networks.
