1-to-4 Gigabit Ethernet Splitter

The Jansicotek OZHW5 expands a single RJ45 connection into four Gigabit ports, letting up to four devices share one network cable simultaneously. It works with Cat5 through Cat8 cabling and suits routers, switches, PCs, TVs and set-top boxes. Any port can serve as input or output, and the adapter requires the included USB power cable to operate.

Thermals noise and power draw

The unit draws power from an 80 cm USB cable connected to a standard socket or port, so it adds no load to the Ethernet line itself. With no moving parts and a compact 4.02 x 3.74 x 1.06 inch enclosure weighing 3.2 ounces, it runs silently and stays cool during continuous use. Per-port LED indicators show link status without generating noticeable heat.

Upgrading from a two-port or single-port setup

If your router or wall outlet only offers one or two RJ45 jacks, this splitter adds the extra ports needed for a desktop, console, streamer and NAS all at once. The jump is worth it when you need four simultaneous 1000 Mbps connections without running new cables through walls. It does not replace a managed switch, so buyers who need VLANs, QoS or more than four ports should look elsewhere.

Questions about this item

How do I install the Jansicotek OZHW5 splitter and what step is often missed?

Connect the incoming Ethernet cable to any RJ45 port, link up to four devices to the remaining ports, then plug the included 80 cm USB power cable into a stable power socket — the splitter will not work without this power connection.

What maintenance or replacement will the Jansicotek OZHW5 need later?

No routine maintenance is required; the unit has no moving parts or replaceable modules, so only the USB power cable or the splitter itself would need replacement if they fail.

What limit appears first when the Jansicotek OZHW5 runs under sustained load?

Each of the four ports is capped at 1000 Mbps, so the aggregate throughput cannot exceed that per-port ceiling even when all four connections are active simultaneously.
