What this splitter does

The ESTONE OZHW5 turns a single RJ45 Ethernet cable into four active ports, letting four devices share one wired connection at the same time. It is built for homes or small offices where running extra cables is impractical and a switch is not desired. The unit requires the supplied USB power cable to operate and will not work without it.

Sustained throughput behaviour

Each of the four ports can reach a maximum chipset speed of 1000Mbps, though actual throughput depends on the connected devices and the single upstream link. Because all four ports share the same physical cable, heavy simultaneous transfers will divide the available bandwidth rather than multiply it. The splitter is intended for typical internet and local-network traffic, not for aggregating multiple full-speed gigabit streams.

Installation notes

Connect the incoming Ethernet cable to the input port, plug the four devices into the output ports, and attach the 80cm USB power cable to a stable USB power source. The package includes the splitter and the USB cord only; no configuration software is required. Ensure the USB supply remains connected, as the device has no internal power and will drop all links if the cable is unplugged.

Questions about this item

Does the USB power cable draw much heat or noise when the splitter runs all day?

The unit is a passive adapter with no fan; the USB cable only supplies 5 V power to the internal switching logic, so it produces no audible noise and negligible heat during continuous operation.

What must I already have to use the four RJ45 ports at once?

You need a single incoming Cat5e or better Ethernet cable from your router or switch, the supplied USB power cable plugged into a 5 V USB port or charger, and up to four devices with RJ45 network ports.

Will my older Cat5 patch cables slow down the 1000 Mbps rating?

Cat5 is limited to 100 Mbps; to reach the splitter’s 1000 Mbps capability you need Cat5e, Cat6, Cat6a, Cat7 or Cat8 cables on all four output runs.
