![]() You can buy cheap media converters for connecting e.g. With fiber there's no need to compensate EM noise or to remove direct current, so you can just put a data signal on the core. There is no reference to ground.įor 10BASE-T and 100BASE-TX there's a dedicated pair each for transmitting data and receiving data. Put in another way, each wire is a reference for the other. ![]() In the simplest example, Transmit+ > Transmit- (higher voltage level) means 1 and Transmit+ < Transmit- (lower voltage level) means 0. Twisted pair uses differential signaling - in a pair, one wire is always the negative/complimentary signal of the other. ![]()
