An Ethernet splitter takes advantage of the fact that 10MBit and 100Mbit Ethernet , even though the cable (almost certainly) contains 8 wires. The splitter consists of two pieces (see picture): one is connected to each end of the existing cable, providing the appearance of two ports at each end. Each link has 4 dedicated wires, so there is no risk of packet collisions. Gigabit Ethernet does require all 8 wires, so 100MBit (full duplex) is the limit through a splitter; a Gigabit switch would be required to increase the bandwidth. Also, if your router only has one Ethernet port, then using a splitter is not an option.
