PoE on 10GBlox?

Does 10GBlox - Compact 10GBASE-T Switch(SKU: BB-10G-A-1) support POE? Or do you have a similar product that can do so?

10GBlox is currently only available to previous customers. We ended up retiring the design due to thermal issues. It has been superseded by UbiSwitch. Neither support PoE.

We do sell PoEBlox that can support PoE.

If you share a little more about your requirements, I might be able to suggest other off-the-shelf hardware you can use with our products to achieve PoE on a 10Gbps ethernet connection in a compact form factor (which is, I assume, why you’re asking about PoE on 10GBlox).

Please advise me the product.

Do you mean to power the 10Gblox by PoE, or the 10Gblox to provide PoE to other devices?

Is 10gb power other device.

If you only need PoE on 1 Gbps ports and only need passive PoE, we use this adapter: MikroTik Routers and Wireless - Products: RBGPOE . You could also try using it with the 10 Gbps ports, but that’s untested.

Also be aware that this is passive PoE (i.e. high voltage all the time, no negotiation). If you connect any active PoE device (802.3af/at/bt), you may damage it when connected to the passive PoE adapter.

Im looking the 10gbe POE using something like this for connection instead of using RJ45.

You can use the PoE injection that @peci1 suggested and just use one of our cables to go from Molex PicoBlade to RJ-45.

The footprint of the POE Injector is too big. If I had various devices that need to be powered on, then I don’t think will work. Other than that, I wish that the POE of the switch can be auto-negotiated, therefore is no need to worry about the user plug in Non-POE Device.
Any recommended product for this?

Ok, so you need active PoE. That’s something that you usually need the switch to do. I believe there are some active PoE injectors but they’re not going to be smaller than what @peci1 has suggested.

PoEBlox which integrates active PoE (up to IEEE 802.3bt (Type 3)) is probably the best solution for you.

Hi, Josh.
I think the POEBLOX doesn’t fit my requirements. I’m looking for an active POE with 10000Base(10gbE).

BTW, Thanks for your help.

10GBE Switch
This will be great if integrate the POE Function. Because I’m using in robotic payload. The footprint needs to be as small as possible. We need a 10gbe switch with POE to power the device and transfer back the data with a maximum 10gbe speed.

Understood, I agree it would be a super useful product. I’ll add this to our development backlog.

We do have a copper 10G Baseboard in development for UbiSwitch. This board will breakout 8 gigabit ports and 3 10G copper ports.

I think we can add PoE functionality to that quite easily. We’ll aim for release April 2024.

Hi, Josh!
Great to hear from you.
Is the copper port you mentioned is the picoblade? Can we use picoblade on 10gbe port switch and RJ45 on the device for the POE Function? The switch should be able to work on non-POE and POE devices. I think it will be a great product, especially for the robotic payload development company.
Hope to hearing soon for the product announcement.

Since we are adding PoE to the wires, we have to consider the current rating of the connector we use for ethernet.

If we are transmitting 90W of PoE (IEEE 802.3bt (Type 4)), with approximately 48V, that’s 1.875A of current.

IEEE 802.3bt (Type 4) uses four pairs, two pairs for V+ and two pairs for V-. This means each two pairs carries 1.875A. Two pairs = 4 wires, so that 1.875A is split across 4 wires, so 0.46875A per contact.

Molex Picoblades can handle 1A per contact, so we should be well within range.


With that all said, we will probably not use Molex PicoBlade. We’re more likely to use Molex PicoClasp on this board. Molex PicoClasp is essentially the same as Molex PicoBlade, but the terminals are locking which makes them a bit more resistant to vibration.

Yes. Hope to hear from you soon. Thanks

Hi Josh.
May I know any suggestions for this Switch to add on POE Function?

It depends on the type of PoE. If it’s just passive PoE (IEEE 802.3af) then you can use a simple injector to inject a voltage onto the ethernet lines. If it’s active PoE (IEEE 802.3at, IEEE 802.3bt (Type 3), IEEE 802.3bt (Type 4)), then you’ll need something that can handle the autonegotiation.

There’s a good range here.


I can’t find anything directly embeddable. This is probably something we’ll develop once our PoE range starts being released.
