Thread-topic: 802.3da MPOE Voltage Change Proposal

Hi Jason,

I am glad that you are proposing to increase voltage to 57V.

I think this is right technical solution and will help market to adapt IEEE802.3da. I hope it will be accepted.

Best Regards

Arkadiy

Following comments by Arkadiy in the last two drafts, I have reconsidered his proposal to increase the maximum MPSE voltage. Please see the attached presentation. I would like the Task Force to consider making the changes outlined in the slide deck during our meeting tomorrow morning.
