Outdoor RB711 or 4xx with optical fiber using mediaconverter

Hi,

do you have a solution for the RB7xx or 4xx outdoor using optical fiber, with a media converter on the outdoor enclosure?

indoor router<—rj45 -->mediaconveter<----fiber -----> (mediconveter<—rj45—> RB7xx or 4xx) outdoor


I see that most of the media converter is working at 5V or 9V DC. So I need some kind of DC-DC converter on the outdoor enclosure, to get the power from the PoE cable at 12 or 24V and convert to 5 or 9V.

What do you use?

That runs @ 24VDC.
