Hi Gui Kang,

PSE devices is only responsible for supplying power over the ethernet cable and don't do anything with the data. So as long as your PHY switch and data transformer can support 10G data rate, the system capable to support 10G. PSE devices are usually picked based on power levels and number of ports. Thanks.

Best regards,

Penny

Thanks Penny.

Here's follow-up question:

We also checked the TPS23880EVM document. In page 2 of that document, it says:

“Two IEEE802.3bt (draft) 4-pair ports with 1000BASE-T (gigabit Ethernet data pass-through)”

That means that the EVM supports only 1Gb Ethernet.

Do you have similar or higher version of PoE EVM (Evaluation Module) that design to run in 10GbE?

In case none, do you plan to create one? Or can you recommend TI third party partner that has EVM that support 10GbE?

Thanks,

Conrad
