Copper Cabling - CompTIA Network+ N10-009 - 1.5 Flashcards
“Transmit+” and “Transmit-“:
These labels indicate the wires used to send data, with the ‘+’ carrying a positive signal and the ‘-‘ carrying a negative signal, effectively canceling out external interference picked up along the cable.
Balanced Pair Operation:
Two wires within a pair carry equal and opposite electrical signals, allowing for noise cancellation when the receiving device compares the signals at the other end.
