Re: [WISPA] Fiber/Copper Combo Wire
There is no reason one couldn't do a custom POE that was AC. A couple thoughts... To maintain a max input of 48VDC, (to be under the low voltage codes), and to deliver 50W topside, is going to require a 14-16AWG wire pair and a 48V 60W supply at the bottom. I suspect that you will need to get some DC-DC converters in various sizes to run the equipment up there... os10ru...@gmail.com wrote: Isn't POE DC?

Re: [WISPA] Fiber/Copper Combo Wire
I'd worry about what would happen as the load varies, specifically if the load gets substantially less which could lead to the device getting overloaded.
