What the splitter does and who needs it

The Jansicotek OZHW5 is a Gigabit Ethernet splitter that turns one RJ45 line into four active ports. It lets four computers or network devices share a single cable run at up to 1000 Mbps per connection. A USB power cable is included and the unit will not operate without it, making it suited for setups where running extra cables is impractical.

When it replaces extra cabling or a switch

This adapter replaces the need to pull multiple Cat5e, Cat6, Cat7 or Cat8 cables through walls or conduits. The jump is worth it when you have only one Ethernet drop but need simultaneous wired connections for devices such as a TV, set-top box, router or PC. Each of the four ports handles full Gigabit throughput without crosstalk between the signal groups.

Installation steps and common pitfalls

Plug the incoming Ethernet cable into any port, connect up to four devices to the remaining ports, then attach the USB power cord to a 5 V USB charger or powered port. The splitter has no fixed input or output, so any port works. The most common issue is forgetting the power connection — the LEDs will stay dark and no data will pass until the USB cable is powered.

Questions about this item

How much space does the 4.02 x 3.74 x 1.06 inch splitter need on a desk or rack?

The unit measures 4.02 by 3.74 by 1.06 inches and weighs 3.2 ounces, so it fits in a tight cable run or on a small shelf without blocking adjacent ports.

The splitter will not work unless the USB power cable is connected — what is the correct way to plug it in?

Connect the 80 cm USB cable to a stable 5 V USB power socket first, then attach the incoming Ethernet cable and up to four Cat5/5e/6/7/8 devices; the LEDs will confirm link status on each port.

Will the USB power cable or the RJ45 ports wear out and need replacement later?

The 80 cm USB power cord is the only external cable supplied; if it becomes damaged it can be swapped for any standard USB-A power lead, while the four RJ45 ports are fixed on the housing and are not user-replaceable.
