Gigabit PoE splitters: power back out, for devices that never spoke PoE

Seven splitter models that take a PoE link in and hand a non-PoE device clean data plus DC power — 5V, 12V and the other rails legacy devices actually eat.

λ.01

The reverse of an injector, and just as useful

A splitter performs the mirror operation of an injector: the PoE link arrives carrying data and power together, and the splitter separates them — Ethernet data out on one port, DC power out on a barrel or USB connector — for a device that has no PoE circuitry of its own. The installed base of such devices is enormous: older IP cameras, single-board computers, USB-powered sensors, access controllers, displays. This family of seven documented models exists to put them on PoE infrastructure anyway.

The family's most instructive model is printed plainly in the catalogue: a 10/100/1000M 5V 2A PoE Splitter with Micro USB port — gigabit data through, 5V/2A out on the connector the device world actually uses. Around it, the family covers the 12V class that cameras and controllers expect and the other documented output variants in the table. The engineering discipline of splitters is unforgiving in one specific way, which the specifying section takes head-on: voltage.

How to specify

Voltage is not negotiable — in either direction

A splitter's output must match the device's required voltage exactly: 12V into a 5V device is destruction, 5V into a 12V device is a brown-out that looks like a network fault. The model names print their outputs; the inquiry should print the device's required voltage and connector, and the pairing is confirmed in writing.

Active vs passive is a safety distinction

Active splitters negotiate with the PSE like a proper powered device and only then output power; passive arrangements pass voltage blindly. For gigabit links and valuable devices, specify active — and use the inquiry to confirm the chosen model's behaviour, including what its output does before negotiation completes.

Current headroom matters at start-up

Devices draw peaks at boot and at motor/IR start. The documented 5V model is rated 2A; match the device's peak draw, not its idle draw, against the splitter's rating.

Questions buyers ask

Splitter or new PoE device — which is cheaper?

For one healthy device, the splitter, almost always: it preserves the device and the cabling. The refresh case wins when the device itself is due for replacement; the splitter is how you avoid coupling a cabling project to a device project.

Can a splitter feed a USB-C device?

The documented micro model is Micro USB. USB-C power delivery is a different negotiation; state the device and connector in the inquiry and the answer will be exact rather than hopeful.

Does the splitter reduce my link speed?

The documented family is gigabit-rate (the 5V model is 10/100/1000M). A splitter is transparent to data at its rated speed.
