A cable splitter, technically a passive RF (Radio Frequency) distribution device, takes a single incoming coaxial cable and divides the signal to multiple outputs. It doesn't amplify the signal; instead, it splits it, resulting in a power loss at each output port. An Ethernet splitter helps manage limited ports by allowing multiple connections from a single Ethernet line. While the concept sounds simple, there is often confusion around how Ethernet splitters work, what they can realistically do, and when they should be used instead of other networking. If you've run out of Ethernet ports but still need a wired connection, you may have come across a small device called an Ethernet splitter. It looks simple enough, just a box or adapter with extra jacks, but its role in your network isn't always clear. Splitters are incredibly cheap, but that's where the positives end. The splitter consists of two pieces (see picture): one is connected to each end of the existing cable, providing the appearance of two ports.
