An industrial switch on the tower doesn't trouble me either.
The objection might be that it's a point of failure for every other
device on the tower. The sync/media converter thing could be also.

How do not have a switch up if you have any form of a SyncInjector
there? “the non-POE side of the injector” needs to go somewhere,
unless you are saying that every POE port has a corresponding fiber
port that would mate with a fiber strand coming down the tower and have
a router with a bunch of SFPs to match.
The S16 is a good model, just add Sync. Extremely simple. No fiber
terminations at the top. (we use MST’s which are a cheap reliable way
to not have to do the tower top terminations) The next models of 16
will have additional SFP ports. I assume when UBNT APs have SFPs is
when the additional SFPs would appear on the S16 type device.
VLANing using a single fiber coming down the tower is a simple task.

What I keep hearing from customers is that they want to run a
multistrand cable up the tower and have an all in one box at the top
which they terminate the cable into, hook up power to it, and then run
short jumpers to their radios. I've heard this from enough different
customers that it seems like a common desire.
They all seem to want the box to do media conversion and power
injection and sync, with remote control and not much more. When
quizzed about just doing a switch and an injector up top, they all
expressed how this was unacceptable.
At this point I'm looking at feasability. I'm not sure if this will
ever see the light of day, a lot depends on the amount of R&D
required.

Forrest,
For what it is worth, when we went Fiber (MST) up the tower, we run
UBNT S16s up there which is simple and working well, and GPS pucks on
the ePMP, or Syncbox 12 (or Junior) for devices that need sync. We
have a handful of 450s, 25 320s, and a dozen or so 900s where we use
the SyncBox.
Been very pleased so far with the reliability of the S16 POE. We VLAN
APs in one group and BH’s each on their own VLAN, and bring it down
the fiber. If we have other devices with fiber, we bring them down on
their own fiber (off the same MST). Of course there is core router
with fiber inputs only being used (with the exception of the
sitemonitor which I may have to buy a media converter for just to
isolate the electrical connection into the router.
So, as far as anything up top, I would think it would have to be some
form of switch, or it would be quite kludgy.

I've torn a couple apart that use a fairly easy to use chipset. But
only available in commercial temperature range.
Some of the battle here is figuring out the vendors who do this type
of stuff. I want to avoid switches since I want this as transparent
as possible, but I might end up having to go there. I have another
secret weapon in my arsenal but I'm hoping I don't have to go there
since that's more software and software takes time.

Yeah, maybe I should be clearer what I'm looking at.
I'm looking at various options to build a tower-top box to simplify
the fiber up the tower with syncronized radios at the top.. Think a
multiport ubiquiti fiberpoe with sync over power and a gps receiver
built in, along with tower-top management.
I don't want to include a switch up top - most people want as little
as possible up there, and I'd rather keep the whole thing as simple
as possible - I'd rather just use a copper-to-sfp chipset, but I
haven't found any which I feel comfortable integrating. So I need
to tear some more of the units apart to figure out what chipsets are
available.

Haven't had one fail due to cold yet that I know of. That's a
switch, so maybe it's more complicated than you're going for.

I want to buy another selection of gigabit copper to sfp converters
for reverse engineering purposes. Ideally some which are known to
work well and especially any which don't fail in non climate
controlled environments.
What is everyone using?
