AF24 DC/Fiber adapter

[petecarlson]

How about an AF24 DC/Fiber adapter that fits inside the AF24 case or could be pole mounted next to it. Isolated DC-DC converter for -/+48VDC and an SFP port? A pole mounted version with selectable POE output could be used on a lot more then the AF24 which might expand the market for the device.

Not sure I follow what your suggesting? Maybe a diagram.

Like a two port DC powered wisp switch (WS-12-250M). One port gig copper, one sfp cage. DC powered. Perfect if it were designed to fit inside of the AF24, perhaps replacing the back door.

I just looked through the smaller wisp switches you are developing and it looks like the WS-12-250M would fit the bill for more dense AF24 sites. A bit overkill if I'm only putting up one AF24 though.

Maybe I am just slow or maybe because I only had a coupe hours sleep but I still do not get it?

I think he wants a Tower Switch to run fiber and DC up the tower to his AF units

I had suggested something like this to UBNT.

Basically a 2 part unit. A fiber to ethernet convertor.

Remote unit: Tower mounted, DC input jack (24 volt to 48+ volts) (unit has it's own internal regulator for itself)
Takes fiber connection in jack, outputs an Ethernet POE cable to the UBNT (or other) radio.
You would need 2 versions of this, a 1 GigE POE one, and a 100 Mbps POE one.
POE output power would be what you put into the unit!

The Base unit:
With mounting ears on it.
DC input jack (or AC transformer unit), takes Ethernet input jack to Fiber output jack. (This could be powered also by 12-48 volts, if the unit had an internal regulator for itself)

These units could be used in many sites, at many voltages!


This would be useful for those long tower runs, or on a "Hot" AM radio tower, or on a remote hill site where you have a super long run to get to it!
DC cabling would be externally connected by whatever means is necessary!

You guys will love our Tower Switch line!!!!

Chris has a preterminated hybrid cable planned for the tower switch that will send power plus fibre up the tower from the IDU to the ODU. So it sounds like you want a dumbed down tower switch with only one copper port that puts out whatever PoE you put into the IDU. Do you want it to use the same hybrid cable or do you want to roll-your-own?

I would guess that would have to be determined by the install?
In most cases you could use the hybrid cable, except say a Hot AM tower, where you would have to use pure non-conductive fiber over the tower insulator, and then use the already installed AC/DC tower lighting on the tower to get your power to the unit.

Not sure why you say this, a composite cable (fiber for data and copper for DC power) will not interfere with them or it with them.
Now there were some trademark things UBNT filed that looked like they were attempting to send DC power in the form of photons(light) across fiber then convert said light to DC on the far end but I know nothing about how that worked out for them? Seems like an expensive large heavy device to me?
