Wirewin 121169 RJ45 Ethernet splitter/combiner, grey

Running a second Ethernet cable through walls or conduits is often messy, costly, and time-consuming. The Wirewin 121169 solves this by letting two devices share one existing Cat5/Cat5e/Cat6 cable run. It splits the 8 wires of a standard network cable into two 4-wire connections, each supporting up to 100 Mbps. Use one unit at each end of the main cable to create two independent network ports from a single cable. Ideal for connecting a PC and a smart TV, IP camera, or game console in the same room without pulling new wires.

Who is it for

Perfect for home users, small offices, and IT technicians who need to expand network connectivity without installing additional cabling. If you have a single Ethernet wall port but two devices nearby, this splitter is a practical, budget-friendly solution.

Tips

For full functionality, you need two Wirewin 121169 splitters: one at the source end (e.g., router or switch) and one at the destination end. Connect the main cable between the two splitters, then plug your devices into the female ports. Note that each split connection is limited to 100 Mbps and does not support Gigabit Ethernet. Avoid using with PoE devices, as the splitter does not pass power.
