I thought it was due to being more resistant to moisture.  I also wonder if the goop in the tube cushions the fiber from being crushed.

Over never heard that comment of loose tube being better for underground. Do you know the reasoning?

    My only reason for sticking with the loose tube drop cable vs the
    900um tight buffer is that it's my understanding that loose tube
    is better for underground.  Maybe I should get past my prejudice
    against tight buffered fiber.

    My guys got good at using a AFL Fast Connect with a 3mm boot and
    getting the distances right to just have the loose tube ending
    inside the boot. Sometimes a piece of heatshrink over the end of
    the boot as well. The loose tube is fairly rigid but it work OK
    in our fairly large NIDs .

    Now we are using tight buffer flat drop  so it just has 900um
    right in the cable. But we also switched to fusion splicing a
    pigtail at the NID so don't use a field install connector any
    more either.

        I'm kind of winging it because I haven't found an example to
        follow.  Is
        there a better way to do this?

        That's the orange bare fiber inside 16" of clear 900um
        furcation tube.
        The connector is an SOC made for 900um cable.  The furcation
        tube is
        pushed about 3/4" into the end of the buffer tube and then a
        piece of
        heat shrink ties the pieces of tubing together.

        It seems durable enough, but it's a lot of finicky pieces. 
        Took about
        10 solid minutes to do this.  I'm sure with practice I can
        shave that
        down, but it just seems like there has to be an easier way.

        In a moment I'll send a pic of why I'm bothering.....
