ESTONE OZHW5 1-to-4 RJ45 Splitter

The ESTONE OZHW5 is a powered Ethernet splitter that expands a single RJ45 port into four female connections. It targets installers who need to share one incoming cable across four devices such as computers, TVs, or set-top boxes without running new wiring. The adapter requires the included USB power cable to function and cannot operate without an external power source. It is not suited for buyers who want a passive unpowered coupler or a managed switch with VLAN support.

Gigabit throughput on Cat5e to Cat8 cables

The splitter handles a maximum chipset rate of 1000Mbps across Cat5, Cat5e, Cat6, Cat7, and Cat8 cables. Actual throughput depends on the connected devices, cable quality, and total traffic shared among the four ports. The single upstream link remains the bottleneck when multiple endpoints transmit simultaneously. It does not increase the bandwidth of the original network link beyond its native capacity.

USB-powered installation with 80 cm lead

An 80cm USB cable supplies power from any standard USB port or wall charger; the supplier recommends a mains socket for stability. Simply connect the upstream RJ45 cable, plug in the four downstream devices, and attach USB power — no drivers or configuration are required. Common issues arise when the USB power source is underpowered or unplugged, causing the splitter to drop all four links instantly. Ensure a reliable 5V supply before deployment.

Questions about this item

Which port count should I choose for my setup?

This model provides exactly four RJ45 output ports from one input, so you can connect up to four devices simultaneously.

What does the 1000Mbps rating mean in daily use?

The chipset supports up to 1000Mbps, but actual throughput depends on the connected devices and cable quality.

Does the USB power cable limit where I can place the splitter?

The included USB power cord is 80cm long, so you need a nearby USB port or charger for stable operation.
