PoE Injectors & Splitters

PoE injectors and splitters add Power over Ethernet to a network link, or take it off again for a device without a PoE input. Types include single-port and multi-port industrial injectors, including DIN rail and wall mount models, splitters with DC outputs, active-to-passive converters and battery-powered injectors for installers. Brands include AMG Systems, Comnet, TRENDnet and Veracity, with high-power models such as the 90 W Veracity VOR-OS-90.

Choosing PoE Injectors & Splitters

Match the injector to the power class the device needs and to the network speed, then choose how and where it will be mounted.

Power class

The TRENDnet TPE-219GI shows the three classes: it supplies PoE (15.4W), PoE+ (30W) or PoE++ (90W). A PoE+ injector such as the Veracity VOR-OS-30-UK supplies up to 30 W for IP cameras and access points. Higher-power cameras need more: the Verint PS60POE gives 60W and is recommended for outdoor PTZ cameras, and the Dahua DH-TAM01GT01GT-75 is a 75W midspan for Hi-PoE speed domes.

Network speed

Gigabit injectors such as the TRENDnet TPE-115GI suit gigabit links, and faster ports need a matching injector: the TPE-219GI passes 2.5G, and the TPE-318GI is 10GBASE-T compliant over CAT6a or better cabling. Devices that take 24V passive PoE need their own injector, such as the Ubiquiti POE-24-12W-G for Ubiquiti 24V devices or the Ruijie RP028-2400500 for Reyee bridges.

Industrial and multi-port

The AMG Systems AMG150-1GBT-P90 has a compact DIN rail or wall mount housing for a wide industrial operating temperature range. The AMG150-1GBT-P90-LV boosts a 9-36VDC or 20-60VDC input to a regulated 53VDC, and the AMG155-1GBT-P90 has an integrated mains power supply. The AMG150-4GBT-4GAT-P480 is an 8 port injector rated −40°C to +75°C.

Splitters and multiplexers

A splitter takes PoE in and gives a non-PoE device separate data and DC power. The Dahua DH-TAS100 gives 12VDC from an IEEE802.3af source, and the TRENDnet TI-SG704 splits a 10G 90W PoE++ signal with an adjustable output for 12V, 16V, 24V or 48V devices. To run two IP cameras over one Cat5/6 cable, use a multiplexer such as the Haydon HAY-POE-MULTI.

Frequently asked questions

What does an ethernet PoE injector do?

An ethernet PoE injector adds power to a network cable so one cable carries data and power together to a device such as an IP camera or access point. It sits between a non-PoE switch and the device, taking data in one port and sending data plus power out of the other. This avoids running a separate mains supply to the device.

What does a PoE splitter do?

A PoE splitter does the reverse job of an injector: it takes a PoE cable and separates the power from the data. The data carries on through a network lead, while the power comes out as a low-voltage DC feed for a device that has no PoE input of its own. Check the splitter output matches the voltage the device needs.

What is a PoE+ injector?

A PoE+ injector is an injector built to the higher-power PoE+ version of the IEEE standard, so it can feed devices that need more power than basic PoE provides. Typical loads include compact PTZ cameras and higher-powered Wi-Fi access points. Higher classes, often sold as PoE++, go further for very demanding devices. Check the device power class before choosing.
