This is actually in the category of what I'm expending a fair bit of R&D on right now.
The challenge comes cost. 150watt per port is very expensive to do when factoring in the DC-DC conversion. 20W is easy. 50W is a bit harder. 150W gets very expensive quickly. As a result, I'm thinking somewhat modular, i.e. pick/choose. I also have to be mindful of the competitors in the space, in that I want to be different in the right ways. The power injection/switching space is quite crowded. -forrest On Sun, Oct 5, 2014 at 2:35 PM, Matt Jenkins via Af <[email protected]> wrote: > Our infrastructure sites look like this: > > Shielded Cables -> 8 or 24port shielded patch panel > -> APC PRM24 with WB Surge Modules > -> PoE Injectors > -> Switch / Router > > PoE Injectors are attached to a Masterswitch. > > > <pipe dream> > I know this probably is not feasible but.... > What I would REALLY like is an active PoE midspan injector (8/24 gigabit > port).
