TRENDnet Unveils Power Efficient Ethernet Switches with GaN Technology
TRENDnet, a global leader and award-winning provider of reliable networking, surveillance, transportation, and power solutions, is announcing today that it has launched PoE++ switches featuring GaN power technology. GaN (gallium-nitride) technology delivers power with increased efficiency with a smaller carbon footprint.
TRENDnet's first two network switches featuring GaN power technology are the 6-Port 2.5G GaN Power PoE++ Switch with 10G SFP+ Ports (TPE-BG5062), and the 9-Port 2.5G GaN Power PoE++ Switch with 10G SFP+ Port (TPE-BG5091). Both switches feature high-efficiency GaN internal power supplies, and deliver up to 95 watts of PoE power per port, ideal for power hungry PoE devices, such as advanced security cameras, high-power access points, digital signage, and access controls.
GaN power technology enables power devices to support better power density, downsizing, thermal capability, and energy conversion efficiency. The result is smaller form factor power supplies with more efficient power delivery. A GaN power supply has up to a 40 percent less footprint compared to traditional power supplies. The increased power efficiency also helps to reduce heat generated by an internal power supply, reducing or eliminating the need for cooling fans.
TRENDnet's 6-Port 2.5G GaN Power PoE++ Switch with 10G SFP+ Ports (TPE-BG5062), and the 9-Port 2.5G GaN Power PoE++ Switch with 10G SFP+ Port (TPE-BG5091) are available now. They can be purchased online on the TRENDnet Store, and worldwide through authorized distributors, resellers, and retail partners. Visit TRENDnet at ISC West 2025 at Booth #12115for a hand-on look at these new GaN switches and more.

"GaN power devices offer great dielectric strength, switching speed, current density, and operating temperature, while reducing on-resistance. High-speed switching can often produce considerable EMI, but with GaN technology, EMI is lowered due to reduced voltage usage and current overshoot," said Evan Davis, senior manager of solutions engineering at TRENDnet. "Ultimately, GaN technology enables us to design and produce smaller PoE switches with a higher power output, but that run much cooler than previous models."Both of TRENDnet's GaN power PoE++ switches feature 2.5GPoE++ ports, which are compatible with existing Cat5e or better cabling, and10G SFP+ ports for ultra-fast connection speeds and long-distance fiber applications. These switches are also backwards compatible with 10/100/1000Mbpsnetwork devices. The sturdy metal housing is both rugged and lightweight, and both switches support over current and short circuit protection.

PoE is the domain of RJ45.
You need to use RJ45 for PoE. Fiber is for your backbone connections. I cant think of any PoE devices that use SFP anyway.
However, a SFP+ port seems to be very limited in available power (some data says 1.5 W but I find transceivers comsuming up to 3 W). This means that power transmission wasn't considered when the standards were created.
Now, I want you to read this next part very slowly. Be very careful to consider each word
These adapters convert an ELECTRICAL signal, to an OPTICAL pulse. OPTICAL pulses CANNOT transmit electricity. The RECIEVER inside the switch has a fiber connection, which accepts OPTICAL PULSES, not ELECTRICITY. SFP+ DOES NOT SUPPORT PoE.
There are no end point devices that support SFP. You need to use a RJ45 connection on both ends, no converters, to transmit power appropriately, or you must use PROPRIETARY solutions.
There is no PoE via SFP/SFP+The available power is for the TRANSCIEVER to convert the ELECTRICAL signal to OPTICAL pulses. It is NOT for running external devices.
You CANNOT run PoE over SFP+ ports, no matter how many converters you stick in them. I dont know how I can make this any clearer.
The ONLY way you can power a PoE device that you are connecting to SFP+, is to use an external media conversion box with its own power supply to convert the signal and add power to the ethernet connection. This is no different to having a switch on the other end of the SFP connection.
So, like I said above, SPF+ is ONLY for the backbone of your network. You cannot run PoE devices off of it. You will need a switch, or the box above, and run RJ45 from the switch to your POE device. It doesnt matter how many converters you shove into it, SFP+ does NOT support POE and cannot transmit power.
