Splitter for shared Ethernet lines

This RJ45 adapter splits one network cable into two female ports so two devices can use a single wired connection at the same time. It draws 3.3 V power from the included 1.2 m USB lead and works with Cat 5 through Cat 7 patch leads. The compact housing measures 45 x 3.5 x 2.1 cm and the pigtail is .8 m long.

Upgrade from single-port wiring

It replaces the need to pull a second cable through walls or conduits when a router or wall plate only offers one jack. The jump is worth it when you have two nearby computers, a TV and a set-top box, or similar pairs that only need 100 Mbps each and you cannot run new cabling.

Limited to 100 Mbps per port

Because the splitter uses a physical tapping method the total bandwidth is divided, so each connected device tops out at 100 Mbps and cannot negotiate Gigabit speeds. The adapter also requires the USB power cable to be plugged in; it will not function on passive power alone.

Questions about this item

What are the exact dimensions of the splitter housing?

The splitter measures 4 cm long, 3.5 cm wide and 2.1 cm deep, with a 0.8 m lead to the USB power plug.

How do I power the adapter correctly?

Plug the included 1.2 m USB cable into any 3.3 V USB port or charger; the splitter will not operate without this external power connection.

When should I expect the gold-plated contacts to wear?

The gold-plated 8P8C pins are rated for many thousands of insertions; replace the adapter only if you see intermittent 100 Mbps links or physical damage.
