Nothing actually has to be done to seal it because, Trango includes a 
rubbery gel sleeve that compresess between the passsthru metal plate and the 
case, with a tight fitting hole. In most cases that can be good enough.

But to answer your question it depends what Fiber cable type and Power type 
you use.  We generally dont run a dedicated power cable through that same 
hole as fiber. We power the radio through one of the CAT5 ports, which has a 
great paththrue grommit type. That way its one less cable to run, and we get 
a redundant data path to the radio. The radio can be POE powered from either 
CAT5 port. There are reasons that you might choose the management vs data 
CAT5 port, dependant on the circumstances.

(It should be noted that both teh data and fiber port can be both used as 
seperate PVLANs, if desired)

So when just fiber going through the Metal base plate, there is not much to 
seal, UNLESS you do not have fiber cable adequate to survive the elements. 
What we often do is we use 3ft of  Flex tubing from the APEX to an outdoor 
junction box, and then patch in fiber there. It can be a hassle finding a 
cheap outdoor junction box. (So we made our own, for half the cost.)

If using direct buriel multi-pair Loose tube, you can run the cable to the 
outdoor junction box and terminate with a fan out kit to a LC jack patch 
panel.  Then use a short patch cable to extend to the APEX.
This type install is rock solid, once its done. But its a pain working with 
Fan-out kits on a windy dirty roof. (If on a tower should probably be done 
on ground first, but on roofs it would not fit through access holes in walls 
and such)

There is also indoor/outdoor Fiber that has an overall outer layer, and then 
each inner layer also has its own individual outer jacket. This type cable 
is cheaper, and can have LC connector connected directly to it, without the 
hassle of a Fanout kit. This cable is also significantly thinner, and can 
fit through APEX passthrough. In these cases, the cable can be run directly 
into the APEX without any junctions inbetween.

We always run Fiber that has two pair (two tx and two rx) so if one fiber 
breaks, there is an immediate spare. There is room to slip both pair with 
conectors inside the APEX, I think.

It should be noted that Indoor and Outdoor fiber are not the same. It is not 
just to prevent physical breaks from getting stepped on, or Firecode/UV of 
sleeve. The mor important issue is that it has a different Temperature 
rating for Cold.  If you use indoor fiber outdoor in cold, it can crack 
internally due to cold. It should be noted that allthough Outdoor fiber and 
Fan-out kits will often have a different part number for its outdoor temp 
rated version. But most patch panels and stuff wont have an outdoor temp 
version.

So, fo this reason, sometimes people perfer to put the fiber inside Flex, so 
its one more level of temperature insulation. Actually we use something 
called Liqui-tight, the grey stuff tthat can be bought just about anyware 
like HomeDepot.

We debated for quite a while, whether we should use sealed FC type 
connectors inside the outdoor enclosure. The outcome was LC patch panels 
were easier to find, and LC patch panels will survive the elements just fine 
in most cases.

As well, its also possible to run long fan outkits, and just run the thin 
inner fibers up through the 3ft of Liqui-tight to the APEX. That will 
survive the elements, if using outdoor temp version. BUT we chose NOT to do 
that because we were afraid that if we performed maintenance and needed to 
disconnect the fiber from the APEX, that the weight of the liqui-tight might 
break the fiber or pull loose from connector, if not careful.
That is why we used a patch panel inside the Junction box, and patch cables 
to the APEX.

We rarely ever run Conduit the whole fiber cable path, its to much of a 
pain. We'd rather use a fiber cable that is of a type that wont easilly 
break. But depending on your install location, you may disagree for your 
situation.  But if you use conduit for the run,  we recommend Liqui-tight, 
its not all that expensive and is easy to run, because you just carry it up 
in the spool.

If you are worried about water intrusion, but dont want to use conduit, you 
can just cut a 6-10" peice of liquitight and screw that to the APEX base 
plate. (They make adapter to integrate to that size I think)
