A device designed to divide a single incoming coaxial cable signal into two separate outputs, enabling the simultaneous connection of two devices. These devices commonly include a cable television receiver and an internet modem. This bifurcation allows both devices to receive signals without direct interference, although signal strength may be affected.
The utility lies in its ability to streamline connections, reducing the need for multiple cable lines running into a residence or building. By utilizing this component, users can efficiently manage their cable and internet connectivity, potentially saving on installation costs and minimizing cable clutter. Early iterations were less efficient, leading to significant signal degradation. Modern advancements have improved the performance, allowing for minimal signal loss and better overall connectivity.
