I’ve never seen such an animal.  Inside a cabinet I’d normally say the buffer 
tube itself is good enough protection.  

 

We’ve been using a FiberOne cassette system which has a door on the rear.  OSP 
cable goes into the panel, and the buffer tubes all end up behind the door.  I 
don’t know how they compare to Clearfield.

 

I’d also wonder if there’s a cover or housing you can screw onto the back side 
of the rack behind your cassette system.  Just cover the buffer tubes with 
steel.

Maybe something like this:

There’s a way I terminated loose tube drop cable.  In the drop cable scenario 
it’s furcation tubing over the 250um and a heat shrink tube to join the 
furcation tube with the buffer tube, and then a bigger heat shrink tube to join 
the drop cable jacket to the smaller heat shrink. Then obviously an SOC or what 
have you goes at the end of the furcation tube.  It works out well for the drop 
cable.  For a similar thing with the buffer tubes you could source a roll of 
2.5mm to 3mm ID tubing of whatever kind of plastic you like.  If you get clear 
tubing you could still see the color of buffer tube.  A 3mm ID tubing would 
have a 5mm OD.  A bundle of twelve 5mm tubes would have a 20mm OD.  Almost 
twice as big as a 144F OSP cable itself, but a 4:1 heatshrink tube should be 
able to squish down on all of it.  The adhesive heat shrink is quite stiff 
after shrinking so it would prevent that joint from bending much…..which is 
desirable I think.  Never done that, but I think it would work.  I’m gonna 
circle back to why though?  You got monkeys playing in the fiber cabinet?

Subject: [AFMUG] Buffer tube breakout kit

 

I'm looking for a kit to break out / protect individual buffer tunes on their 
way to a clearfield patch and splice cassette.  Just something to clamp on the 
end or the cable and protect the buffer tubes on the way to the cassettes 
inside the cabinet, not to breakout the individual fibers.  Like a spider kit 
except just to feed the buffer tubes into.  Anyone know of anything like this?
