The two examples here show the differences between Gigabit devices and 10- and 100-Mbps devices. With a Gigabit device it is possible to view real live data on all four pairs whereas a

10-Mbps and 100-Mbps device can only transmit on one pair. A Gigabit device is a full-duplex device that uses two pairs to transmit and two pairs to receive data, and it can be tricked into displaying the data on the two receiving pairs. That makes it a perfect device to get a full view of all four pairs of the cable.
