Gigabit Ethernet Splitter 1 to 2 Ports

The Jansicotek OZHW3 adds two RJ45 ports to a single Gigabit network connection, letting two devices share one cable run. It is aimed at home or small-office users who need extra wired ports without running new cables or buying a managed switch. The adapter requires the included USB power cable to operate and cannot function without a power source. LED indicators show the link status for each port.

Replaces Extra Cabling or a Larger Switch

This splitter upgrades a single wall jack or router port into two simultaneous 1000 Mbps connections, removing the need to pull additional Cat5e through Cat8 cables through walls. The jump is worth it when you have exactly two nearby devices — such as a PC and a smart TV — and no spare switch ports or patch-panel capacity. It will not help if you need more than two ports or if the upstream link is limited to Fast Ethernet speeds.

Plug-and-Play With Mandatory USB Power

Installation is straightforward: connect the upstream Ethernet cable, plug the two downstream devices into the RJ45 jacks, and attach the USB power cord to any 5 V USB port or charger. The most common issue is forgetting the power connection, which leaves the splitter completely inactive. Another pitfall is expecting full 1000 Mbps throughput on both ports at once; total bandwidth is shared across the single upstream link.

Questions about this item

What physical space does the 4.02 x 3.74 x 1.06 inch adapter need?

The splitter measures 4.02 by 3.74 by 1.06 inches and weighs 3.2 ounces, so it fits on a desk or behind a router without brackets.

How do I install the splitter and what step is often missed?

Connect the incoming Ethernet cable to the single RJ45 input, plug two devices into the two output ports, then attach the 80 cm USB power cable to a 5 V USB socket — the unit will not work without this power connection.

What maintenance or replacement will the USB power cable need later?

The included 80 cm USB charging cable may wear or be lost over time; any standard USB-A to micro-USB cable supplying 5 V can replace it to keep the splitter powered.
