Gigabit PoE Splitter: TRENDnet TPE-104GS



What is a PoE Splitter?

PoE refers to Power Over Ethernet. A network cable coming from a PoE-enabled port of a PoE Switch (or) from a PoE injector carries both data and power. When this cable connects to a PoE-enabled device on the other side, both data and power can be provided using just one cable.

But not all devices are PoE enabled. Some need to be powered using a regular AC to DC adapter. If you don’t have a power plug nearby, you might find it difficult to bring power cables from far away. But why not just use the network cable coming from a PoE switch, after separating the power and data?

That’s what the PoE Splitter does. It connects to the network port of a PoE Switch on one end, which provides both data and power on the same cable. The Splitter separates data and power. There are two outputs coming out of the splitter: One for data connection using a network cable, and another for power connection using a power cord. These two can be connected to the Non-PoE device separately.

Remember that while a PoE Injector combines data and power and sends it on a single cable, a PoE Splitter separates data and power and sends each on separate cables. So the PoE Splitter is the reverse of a PoE Injector.

The TRENDnet TPE-104GS is a popular Gigabit PoE Splitter. Let’s look at the main specs, advantages, and limitations of this device.

Main Specifications of TRENDnet TPE-104GS PoE Splitter:

  • PoE Splitter: Splits a Gigabit Data (+) PoE signal into Gigabit Data (&) Power separately
  • User selectable output power: 5V, 7.5V, 9V, 12V
  • Dip switch and LED indicators for power selection and indication
  • Input: Connection from PoE switch or PoE Injector
  • Output: Power: 2 to 2mm, 2 to 2.5mm jumper power cables to connect to the Non-PoE device; Gigabit Ethernet data port
  • Compatible with 802.3af PoE network connections
  • Gigabit Ethernet Ports x 2 (input and output), Power output port x 1
  • PoE Input: 48V DC, 0.38A
  • Operating Temperature: 0-45 Deg. C
  • Warranty: 3 years

Advantages of TRENDnet TPE-104GS:

  • Supplies power and data separately to Non-PoE devices like Routers, Access Points, Bridges, Extenders, IP Cameras, IP Phones etc. (that doesn’t support PoE).
  • 802.3af PoE Switch (input) is commonly available.
  • It’s a compact unit.
  • Ideal for connections between a PoE Switch and a Non-PoE network device located on a remote location without easy access to a power plug.
  • Saves on installation and equipment costs, and reduces the time required to install a Non-PoE device at a remote location.
  • There is no need to connect a separate power supply to the Gigabit PoE Splitter as it is a passive device.
  • Built-in mounting points make installation on walls/ceilings easier.
  • Supports Gigabit speeds of up to 2000 Mbps (full-duplex).
  • Compact device, easy to conceal.
  • Simple to install and not much maintenance.
  • The Non-PoE device that is connected via this splitter need not be Trendnet. It can be of any make.

Limitations/Tips:

  • The PoE splitter has to be installed close to the Non-PoE device like the camera or access point.
  • In some cases, it maybe difficult to conceal the unit.
  • This unit supports only the PoE standard and not the more recent PoE+ standard.
  • The user-selectable output voltage ranges from 5 to 12V, so this device cannot be used to power equipment that requires higher voltage.
  • Network Cables (Cat 5E/6) are not supplied with the splitter.
  • Tip: It’s a good idea to ensure the PoE switch is grounded properly.
  • Tip: Check the power requirements of the Non-PoE device you want to power using this splitter. If it is 5, 7.5, 9, or 12V, you could use the splitter to power it.
  • Tip: The voltage selector should be set to the required voltage before any power is applied to the PoE splitter through the cable. Not afterwards.
  • Tip: If you want to connect a PoE-enabled device on the remote end, you don’t need the splitter.
